Available in PDF, EPUB and Kindle. Book excerpt: This state of the art report from an international task group (TG44) of CIB, the International Council of Building Research Organizations, presents a highly authoritative guide to the application of innovative technologies on response control and seismic isolation of buildings to practice worldwide. Many countries and cities are located in earthquake-prone areas making effective seismic design a major issue in structural engineering. Reassuringly, structural response control and seismic isolation have advanced remarkably in recent years following numerous studies internationally. Several major conferences have been held and reports have been written but little has been issued on the application of the technologies to good structural engineering practice. Plugging that gap, Response Control and Seismic Isolation of Buildings presents researchers in structural engineering (dynamics) and construction management with up-to-date applications of the latest technologies.

This book was released on 2021-12-15 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seismic resilience of new and existing structures is a key priority for the protection of human lives and the reduction of economic losses in earthquake prone areas. The modern seismic codes have focused on the upgrade of the structural performance of the new and existing structures. However, in many cases it is preferrable to mitigate the effects of the earthquakes by reducing the induced loads in the structures using seismic isolation and response control devices. The limited expertise in the selection and design of the appropriate system for new and existing structures is the main challenge for an extensive use of seismic isolation and response control systems in practice. This document aims to provide a practical guide by presenting a collection of the most commonly used seismic isolation and response control systems and a critical evaluation of the main characteristics of these systems. Comparisons of the key parameters of the design processes for new buildings with seismic isolation are presented, while the application of seismic isolation systems and response control systems for the retrofitting of existing structures is also examined, followed by various case studies from Greece, Japan, Mexico, New Zealand, and Turkey.

Download or read book Seismic Control Systems written by S. Syngellakis and published by WIT Press. This book was released on 2013 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthquakes remain largely unpredictable and potentially catastrophic, a matter of continuous concern to communities in affected zones. Scientists and engineers have made a considerable effort to mitigate their consequences through the design of effective protective devices. New concepts have recently been developed to address the requirements for better structural performance and a more effective use of new materials at a lower cost.This book disseminates knowledge and increases awareness on this very critical subject and thus ultimately contributes to a safer structural design against earthquakes. It comprises a number of articles taken from recent editions of Transactions of the Wessex Institute covering a wide range of topics within the subject of seismic protection through vibration control devices.The first four papers provide a very comprehensive review of existing seismic control designs highlighting their variety, the effectiveness of their performance, as well as the extent of their use for the protection of various types of structures world wide. Most articles deal with anti-seismic devices implementing passive control of structural response through seismic isolation and energy dissipation. Testing and modelling energy-dissipating systems are also extensively covered in the book.It is also important to understand how existing structures fitted with seismic control devices perform against earthquakes. Two such case studies are included in the book; a roof isolated from the top of an existing structure and a bridge supported on both isolating and damping systems. Finally, new analytical approaches for optimising the performance of tuned mass dampers are detailed in two companion papers.

Download or read book Seismic Isolation Structural Health Monitoring and Performance Based Seismic Design in Earthquake Engineering written by Azer A. Kasimzade and published by Springer. This book was released on 2018-08-13 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book features chapters based on selected presentations from the International Congress on Advanced Earthquake Resistance of Structures, AERS2016, held in Samsun, Turkey, from 24 to 28 October 2016. It covers the latest advances in three widely popular research areas in Earthquake Engineering: Performance-Based Seismic Design, Seismic Isolation Systems, and Structural Health Monitoring. The book shows the vulnerability of high-rise and seismically isolated buildings to long periods of strong ground motions, and proposes new passive and semi-active structural seismic isolation systems to protect against such effects. These systems are validated through real-time hybrid tests on shaking tables. Structural health monitoring systems provide rapid assessment of structural safety after an earthquake and allow preventive measures to be taken, such as shutting down the elevators and gas lines, before damage occurs. Using the vibration data from instrumented tall buildings, the book demonstrates that large, distant earthquakes and surface waves, which are not accounted for in most attenuation equations, can cause long-duration shaking and damage in tall buildings. The overview of the current performance-based design methodologies includes discussions on the design of tall buildings and the reasons common prescriptive code provisions are not sufficient to address the requirements of tall-building design. In addition, the book explains the modelling and acceptance criteria associated with various performance-based design guidelines, and discusses issues such as selection and scaling of ground motion records, soil-foundation-structure interaction, and seismic instrumentation and peer review needs. The book is of interest to a wide range of professionals in earthquake engineering, including designers, researchers, and graduate students.

Download or read book Seismic Isolation Strategies for Earthquake Resistant Construction written by Mikayel Melkumyan and published by Cambridge Scholars Publishing. This book was released on 2018-10-15 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthquakes are catastrophic events that cause huge economic losses due to the vulnerability of the existing building stock. However, collapses of vulnerable buildings can be avoided if preventative measures, such as enhancement of their earthquake resistance, are implemented on time. This book will allow the reader to become acquainted with a number of unique, modern and cost-effective seismic isolation strategies, which can be easily, and in very short periods of time, and without interruption of the use of the buildings, implemented with high efficiency in existing buildings, making them earthquake proof. An important aspect here is that the book’s seismic isolation strategies are demonstrated on real examples of existing buildings with different structural systems, such as reinforced concrete frame buildings with shear walls and stone buildings with load-bearing walls. The cost-effectiveness of the suggested strategies is further proved by comparative analyses carried out for buildings both with and without seismic isolation systems.

Download or read book Seismic Response of Base Isolated Buildings Considering Pounding to Moat Walls written by Armin Masroor Shalmani and published by . This book was released on 2013 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seismic isolation offers a simple and direct opportunity to control or even eliminate damage to structures subjected to ground shaking by simultaneously reducing deformations and acceleration demands. A base isolation system decouples the superstructure from the ground resulting in elongation of fundamental period of the structure and reducing the accelerations transferred to superstructure during ground shaking. However, increasing the fundamental period of the structure is mostly accompanied by increased displacement demands. In base isolated structures, this large displacement is concentrated at base level where seismic isolation devices are installed and designed to handle these large deformations without damage. A typical base isolated basement design requires a space in which the building is free to move sideways without hitting the surrounding structure. This space is commonly referred to as the "moat". Structural design codes such as ASCE 7-05 that regulate the design of buildings incorporating seismic base isolation systems require the minimum moat wall clearance distance equal to the maximum displacement at the base of the structure under the Maximum Considered Earthquake (MCE), although the superstructure is designed for design basis earthquake (DBE) level. Despite the cautious regulation for moat wall gap distance, pounding of base isolated buildings to moat walls has been reported in previous earthquakes. In conventional structures, the pounding problem between adjacent structures of buildings and highway bridges has been a major cause of seismic damage, even collapse, during earthquakes in the past several decades. Current design specifications may not adequately account for the large forces generated during impact in base isolated buildings. This study investigates the pounding phenomenon in base isolated buildings from both experimental and analytical perspectives by conducting shake table pounding experiments, developing effective models for impact to moat walls and evaluating the adequacy of code specifications for the gap distance of moat walls. A series of prototype base isolated moment and braced buildings designed by professional engineers for the purpose of this project is presented and one of the models was selected for a quarter scale shake table test with moat walls. The pounding experiments indicate that the contact forces generated during pounding can induce yielding in the superstructure and amplify the response acceleration at all stories of the building. The response amplification and damage depends on the gap distance, moat wall properties, and impact velocity. A detailed finite element model of the test setup is developed in OpenSees. An analytical study on the dynamic behavior of the moat walls resulted in proposing a new impact element. Numerical simulation using the proposed impact element compares well with experimental results. A series of collapse studies using the Methodology in FEMA P695 was conducted for both prototype models at various gap distances. The collapse probability of base isolated models used in this study and the effect of moat wall gap distance on the probability of collapse for base isolated structures is investigated. These studies verify that pounding to moat walls at the required gap distance by ASCE7-05 result in acceptable probability of collapse for the flexible and ductile moment frame models examined. However, the braced frame shows a notable drop in collapse margin ratio because of pounding to moat wall at the required gap distance and requires increasing the gap distance by 17%. to have an acceptable collapse probability.

Download or read book Performance of Innovative Controlled Buildings Under Resonant and Critical Earthquake Ground Motions written by Izuru Takewaki and published by Frontiers Media SA. This book was released on 2018-11-23 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: This eBook is the fourth in a series of books on the critical earthquake response of elastic or elastic-plastic structures under near-fault or long-duration ground motions, and includes six original research papers which were published in the specialty section Earthquake Engineering in ‘Frontiers in Built Environment’. Several extensions of the first eBook, the second eBook and the third eBook are included here. The first article is on the comparison of earthquake resilience of various building structures including innovative base-isolation systems and control systems. Pulse-type ground motions and resonant harmonic ground motions are used for investigating the earthquake resilience of those innovative building structures. The second article is concerned with the performance of an innovative seismic response controlled system with shear walls and concentrated dampers in lower stories. The resonant one-cycle sine waves and resonant harmonic waves are used as the input ground motions. The third article is related to the robustness evaluation of a base-isolation building-connection hybrid controlled building structure under the critical long-period and long-duration ground motion. The multi impulse is used as a substitute for a long-period and long-duration ground motion and the model reduction to a single-degree-of-freedom (SDOF) system is conducted to propose a simple response evaluation method. The fourth article is an extension of the previously proposed energy balance approach to a damped bilinear hysteretic SDOF system under a double impulse as a substitute for a near-fault ground motion. The energy absorption through viscous damping is incorporated appropriately in the energy balance and the application of the proposed method to actual recorded ground motions is presented. The fifth article is on the robustness evaluation of base-isolation building-connection hybrid controlled building structures considering uncertainties in deep ground. The earthquake ground motion amplitude at the earthquake bedrock is evaluated by the Boore’s stochastic method in 1983 including the fault rupture and the wave propagation into the earthquake bedrock. Then the phase angle property at the earthquake bedrock is investigated by introducing the concept of phase difference which is defined for each earthquake type. A wave at the ground surface nearly resonant to the base-isolation building-connection hybrid controlled building structure is produced by considering uncertainties in deep ground. The sixth article is concerned with the critical response of nonlinear base-isolated buildings considering soil-structure interaction under a double impulse as a substitute for a near-fault ground motion. The complicated model of a nonlinear base-isolated building on ground is modeled into an SDOF system after a few model reduction processes. The approach presented in this eBook, together with the previous eBooks, is an epoch-making accomplishment to open the door for simpler and deeper understanding of structural reliability and resilience of built environments in the elastic-plastic and nonlinear range.
