This book was released on 2014 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hurricane impacts have caused significant damage to residential and commercial structures, producing billions of dollars in insured losses. Numerical models are widely used by insurance companies in the prediction of loss cost. Several such loss projection models have been developed by private industry, and the State of Florida sponsored development of a non-proprietary hurricane loss model, known as the Florida Public Hurricane Loss Model (FPHLM). This model resulted from a multi-university effort to quantify the damages and cost of repairs for structures that have been subjected to hurricane force winds. The original FPHLM focused on single-family residential housing. The model is now extended to cover commercial-residential buildings ranging from multi-story apartments to the high rise condominiums typically found lining the beaches of South Florida. This paper proposal focuses on the development of the exterior vulnerability component of the commercial-residential model, and provides a description of the strategies to probabilistically quantify physical exterior damage for two models: low-rise and mid/high rise commercial-residential structures.

Available in PDF, EPUB and Kindle. Book excerpt: This collection focuses on the development of novel approaches to address one of the most pressing challenges of civil engineering, namely the mitigation of natural hazards. Numerous engineering books to date have focused on, and illustrate considerable progress toward, mitigation of individual hazards (earthquakes, wind, and so forth.). The current volume addresses concerns related to overall safety, sustainability and resilience of the built environment when subject to multiple hazards: natural disaster events that are concurrent and either correlated (e.g., wind and surge); uncorrelated (e.g., earthquake and flood); cascading (e.g., fire following earthquake); or uncorrelated and occurring at different times (e.g., wind and earthquake). The authors examine a range of specific topics including methodologies for vulnerability assessment of structures, new techniques to reduce the system demands through control systems; instrumentation, monitoring and condition assessment of structures and foundations; new techniques for repairing structures that have suffered damage during past events, or for structures that have been found in need of strengthening; development of new design provisions that consider multiple hazards, as well as questions from law and the humanities relevant to the management of natural and human-made hazards.

This book was released on 2013 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Florida Public Hurricane Loss Model is a catastrophe model commissioned by the State of Florida with the primary purpose of predicting insured losses of residential buildings due to hurricanes. The model has been in a state of ongoing development since 2001, and is contributed to by several universities around the state of Florida. The model is comprised of three main components. The Meteorological Component predicts and models hurricane behavior. The Vulnerability Component predicts and models building damage given specific wind conditions. Lastly, the Actuarial Component takes data from the other two to predict and analyze economic losses. This paper presents several updates to the Vulnerability Component of the model. First, a more realistic cost analysis is presented, created based on information gathered from actual building contractors as well as RS Means. The new cost analysis includes updates such as unit costs that scale with repair size, considerations for actual roof repair methodology, and various other factors specific to the particular building requirements and market conditions of Florida. Second, an analysis of Contents (as well as ALE) vs. Building damage curves (aka Type 2 curves), which allow the Vulnerability Component of the model to be validated independently of the Meteorological Component, is presented. A procedure for their use in model validation is also given, along with a brief sample validation which illustrates the usefulness of the Type 2 curves in uncovering hidden issues with the model. Finally, a brief study analyzing the effects of the changes made to the wind provisions of ASCE 7-10 is presented. The study shows that the changes implemented in ASCE 7-10 will have little effect, in the case of low-rise, personal residential buildings, on actual building practices in the state of Florida.

Book excerpt: Focusing on fundamental principles, Hydro-Environmental Analysis: Freshwater Environments presents in-depth information about freshwater environments and how they are influenced by regulation. It provides a holistic approach, exploring the factors that impact water quality and quantity, and the regulations, policy and management methods that are necessary to maintain this vital resource. It offers a historical viewpoint as well as an overview and foundation of the physical, chemical, and biological characteristics affecting the management of freshwater environments. The book concentrates on broad and general concepts, providing an interdisciplinary foundation. The author covers the methods of measurement and classification; chemical, physical, and biological characteristics; indicators of ecological health; and management and restoration. He also considers common indicators of environmental health; characteristics and operations of regulatory control structures; applicable laws and regulations; and restoration methods. The text delves into rivers and streams in the first half and lakes and reservoirs in the second half. Each section centers on the characteristics of those systems and methods of classification, and then moves on to discuss the physical, chemical, and biological characteristics of each. In the section on lakes and reservoirs, it examines the characteristics and operations of regulatory structures, and presents the methods commonly used to assess the environmental health or integrity of these water bodies. It also introduces considerations for restoration, and presents two unique aquatic environments: wetlands and reservoir tailwaters. Written from an engineering perspective, the book is an ideal introduction to the aquatic and limnological sciences for students of environmental science, as well as students of environmental engineering. It also serves as a reference for engineers and scientists involved in the management, regulation, or restoration of freshwater environments.

Download or read book Interior Damage Prediction in Residential Buildings Due to Hurricane Induced Rain Penetration written by Timothy James Johnson and published by . This book was released on 2015 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Catastrophe modelers are responsible for estimating and predicting expected physical and monetary building losses under extreme uncertainty. In the case of hurricanes, interior damage might represent the majority of the repair bill so accurate estimates of the interior damage are paramount to a reliable predictive model. Recent studies have shown that wind-driven rain (WDR) is the predominant source of interior related losses even in the absence of visible exterior physical damage. Significant strides have been made in quantifying the external WDR deposition characteristics during hurricane events, and in identifying sources of WDR intrusion through the building envelope. Recent laboratory tests have measured the so-called rain admittance factor (which quantifies the direct impinging rain) and surface runoff coefficients (which quantify the rain surface run-oft) on buildings subjected to hurricane winds and rain. In addition, post-disaster reconnaissance surveys, following hurricanes landfalls in Florida, have shown that soffits are an important source of water penetration, which is not always specifically taken into account in current vulnerability models. Follow-up laboratory tests have measured the amount of the water penetrating through certain types of soffits. These issues of water intrusion are compounded by the fact that a hurricane rotates around any particular building. Therefore the amount of horizontal rain exposure and penetration on any particular facade or component of the building envelope will vary in time as the storm rotates, while the components go from windward to leeward exposure or vice-versa. This dissertation addresses these issues. First, a new vulnerability model for the soffit incorporates experimental data on soffit rain penetration. Second, a new method captures the effect of the storm rotation on the rain deposition and penetration, which is essentially time dependent, into an existing vulnerability model, which simulates both pressure and debris induced envelope breaches but without an explicit time component. Third, a new interior vulnerability model incorporates the new experimental data on building envelope rain deposition and surface runoff. The model succeeds in evaluating the total volume of water penetration though both defects and breaches of the envelope (including soffits), which is then transformed into interior damage. Several implementation strategies were investigated, and the final version was incorporated into version 6.1 of the Florida Public Hurricane Loss Model. This work emphasizes the critical role WDR plays in interior damage as well as provides insights into future mitigation strategies with regard to WDR management.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The core of this model is a Monte Carlo Simulation engine that generates damage information for typical Florida homes, using a component approach. The simulation compares deterministic wind loads, and the probabilistic capacity of vulnerable building components to resist these loads, to determine the probability of damage. In this manner, probabilistic structural damage is identified over a range of assigned wind speeds. Monetary loss associated with structural damage and the likelihood of occurrence for discrete wind speeds will be determined by models under development by other groups in the project.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal residential buildings are vulnerable to significant damage due to hurricane related hazards such as storm surge, wind loads, and inundation. Recent damage to residential buildings caused by hurricanes in coastal areas illustrates poor performance of coastal structures against hurricane related hazards, which indicates that recent standards and building code provisions need to be improved in terms of loading and design requirements. A fundamental problem with current standards is that most follow the deterministic approach to some extent. For instance, both uncertainties regarding flood hazards and building structure characteristics such as elevation, number of stories, and size have not been considered in current flood risk assessment methods, which causes many concerns in terms of validity and reliability. On the other hand, Performance-Based Engineering (PBE) methodology is a well-known design approach to address inherent uncertainties for assessing and mitigating the risk associated with engineering structures. However, with only limited PBE frameworks in hurricane engineering fields proposed during recent years, there is lack of sufficient understanding of different aspects for development of standards needed for hurricane resistant design and retrofit of residential buildings. Furthermore, given the concurrent multi-hazard nature of hurricanes, designers need to address more complex loading conditions and design decisions. Based on the performance of coastal residential buildings in past hurricanes, elevating the lowest floor above the expected Base Flood Elevation (BFE) has been found to be the most effective strategy to reduce direct damage caused by flood and storm surge. However, elevated buildings can be exposed to different levels of wind loads due to unique aerodynamic characteristics, which leads to the need for more stringent design of structural and foundation systems. In addition, past hurricanes have shown that the actual flood levels can be several feet higher than the BFE, which means even pile-elevated houses may still be vulnerable to damage. Therefore, some communities encourage homeowners to add freeboard to the specific BFE in order to mitigate the risk of damage. The amount of freeboard depends on many factors, for which there is no rational approach for building owners and designers to make the most efficient decision. This study proposes a probabilistic framework in order to investigate the combined interaction of hurricane wind and coastal surge flood on typical residential homes upgraded based on various retrofit strategies. The goal of developing such a framework is to contribute to holistic and quantitative approach in evaluating the potential damage to retrofitted, particularly elevated coastal residential buildings. This proposed probabilistic framework consists of four main modules, namely hazard analysis, structural analysis, damage assessment, and loss measurement. A literature review was carried out to evaluate the performance of coastal residential buildings with respect to direct and indirect damage. The result of the literature review on mitigation techniques are discussed according to hurricane wind and flood-related hazards. Identification and quantification of these hurricane-associated hazards is the first step to understanding the behavior of residential buildings and identifying common failure mechanisms and mitigation techniques. The Computational Fluid Dynamic (CFD) analysis was performed to obtain realistic loading scenarios (wind and wave effects) and corresponding engineering demand parameters, respectively. A comprehensive parametric analysis was conducted to understand the effect of various factors, including wind angle, wave type (regular and irregular waves), building elevation, and pier distribution on wind- and wave-induced loads on elevated coastal residential buildings. The CFD models were validated based on available data in terms of wind and wave loadings separately due to lack of current laboratory experiments. The resistance capacities and statistical characteristics for various building components under positive and negative pressures were obtained from experimental tests available in the literature review. The procedure relies on the Monte Carlo Simulation (MCS) to propagate uncertainties through the CFD analysis. Finally, damage assessment and vulnerability analysis were conducted based on selected failure criteria (e.g., HAZUS database) to develop physics-based fragility curves based on four different damage states, and finally obtain loss curves in terms of the building elevation for the selected residential building. A typical wood-frame residential building was selected for the case study to develop the fragility curves for four damage states and the corresponding loss curve based on HAZUS-MH. The building was assumed to be located in the Bolivar Peninsula, where it was heavily impacted by Hurricane Ike as a Category 2 storm. The fragility curves and loss curve were developed for two different scenarios: the building with 8d and 6d common nails used for the connection of roof and floor sheathings. These loss curves predict the expected damage ratio of the building due to combined effects of wind and waves considering the specific house elevation, which can help design professionals and home builders in order to select a reasonable freeboard above the base flood elevation determined based on a probabilistic approach rather than available deterministic methods. This framework can also be utilized in risk assessment and decision analysis of other types of structures against various environmental hazards.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Hurricanes can cause extensive damage to the building and the envelope systems of commercial buildings as documented over the past several decades in the United States. This study focuses on improving the performance of commercial buildings and minimizes losses caused by hurricane hazards. For this reason, the study intends to develop a better understanding of the performance of glass panels as building envelope that helps in performance design methodology.The objective of this study is to make contributions to the Performance-Based Engineering (PBE) design based on fragility information developed from actual hurricane reports. The fragility curves for the failure of glass panels of building envelope caused by wind-borne debris (WBD) give the loss for the exterior of the building, which leads to immediate damage, while the fragility information of wind-driven rain (WDR) through the broken glass panels provides the loss the interior of the building.The approach that will be followed or developed as appropriate can be used in the more practical application of Performance-Based Hurricane Engineering that can result in mitigating building envelope losses due to hurricane effects.
