Download or read book The Seismic Rehabilitation of Historic Buildings written by Antonio Aguilar (Architect) and published by Government Printing Office. This book was released on with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Preservation Brief provides information on how earthquakes affect historic buildings, how a historic preservation ethic can guide responsible retrofit decisions, and how various methods of seismic rehabilitation can protect human lives and historic structures. The Brief provides a description of the most common vulnerabilities of various building construction types and the seismic strengthening methods most often needed to remedy them. A glossary of technical terms is also provided at the end of the Brief. Undertaking the seismic rehabilitation of a historic building is a process that requires careful planning and execution, and the coordinated work of architects, engineers, code officials, contractors, and agency administrators. Project personnel working together can ensure that the architectural, structural, financial, programmatic, cultural, and social values of historic buildings are preserved, while rendering them safe for continued use.

Download or read book Seismic Risk and Post earthquake Recovery of Older Tall Buildings with Welded Steel Moment Frames written by Francisco Alfonso Galvis López and published by . This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the existing tall buildings in the United States use seismically non-conforming welded steel moment frames (WSMFs) of the kind that experienced premature brittle fractures during the 1994 Northridge earthquake. Despite their known vulnerabilities, the vast majority of existing tall WSMF buildings have neither been evaluated nor retrofitted. To support the development of risk management policies for these structures, this study tackles the main impediments to robust quantification of risk and post-earthquake consequences in tall WSMFs by developing (1) a high-fidelity model to improve the nonlinear simulation of fracture-critical connections, (2) a detailed database of a realistic portfolio of tall WSMF buildings to increase the resolution of seismic risk assessments, (3) a screening method for pre-earthquake evaluation of tall WSMF buildings, (4) a damage evaluation method to inform post-earthquake re-occupancy and safety cordon decisions, and (5) a state-of-the-art assessment of earthquake damage, repair cost, and recovery time of tall WSMF buildings. This research presents a new computational model capable of reliably simulating fracture and post-fracture response of welded beam-to-column connections. This model uses a fiber-section element that simulates the welded flanges with single fibers and the shear tab bolted connection with multiple fibers. The flange fibers use a uniaxial stress-strain model that characterizes fracture resistance using a low-cycle fatigue damage rule based on the weld toughness--measured in terms of Charpy-V-notch (CVN) fracture energy--and weld defect size (a0). This stress-strain model also enables a realistic simulation of the connection behavior after flange fracture by capturing crack opening and closure. The stress-strain model is implemented in the OpenSees software as a uniaxial material called, SteelFractureDI. The parameters of SteelFractureDI are calibrated using a comprehensive database of 100 large-scale beam-column connection tests that were digitized and compiled as part of this study. SteelFractureDI is capable of predicting the instant of flange fracture within one half-cycle from the observed instant for 80/100 tests, compared to the 48/100 obtained with state-of-practice rotation limits (ASCE/SEI 2017). Moreover, the proposed connection model provides a more realistic distribution of flange fractures than conventional plastic hinge models due to the proper simulation of post-fracture behavior that avoids fictitious concentrations of drift. The resolution of the proposed connection model is best exploited in structural models that consider the unique features that dominate the seismic behavior of buildings. Thus, we collected a database of the structural characteristic of 89 tall steel moment frame buildings in San Francisco, which are representative of the construction practices in the western U.S. from the 1960's through early 1990's. The information in this database facilitates the creation of high-fidelity nonlinear structural models for several buildings in the database. The seismic response and collapse safety of these building are evaluated using nonlinear response history analyses (NLRHA) under suites of earthquake ground motions at various intensities. This study shows that the collapse safety varies significantly across the portfolio, from collapse risks that are comparable to that expected for current-code buildings to risks that are up to 35 times higher. Furthermore, the estimated performance of WSMFs is especially sensitive to the toughness and quality of the welded connections. These findings motivate broader coordination between structural engineers and public building departments to collect and synthesize data on weld metal toughness. The rigorous collapse metrics from this study enable the development of a rapid screening method to classify the risk of a tall WSMF building as moderate, high, or exceptionally high. This screening method empowers engineers to estimate the relative risk of a tall WSMF building using only basic information on the framing configuration and properties available from structural drawings and linear structural analyses, avoiding time-consuming nonlinear simulations. The screening method is intended to have sufficient specificity to identify the unique building features that influence collapse safety, while being simple enough to expedite the structural evaluation of tall buildings. This screening method can inform preventive decisions, such as whether a building should be prioritized for seismic retrofitting. In high-seismic regions, an earthquake may occur before buildings are retrofitted. Thus, this study also addresses the key post-earthquake issue of determining whether damaged buildings are safe to reoccupy, prior to and during repairs. Using the results of sequential NLRHA on eight WSMF models, we quantify the relationship between an "unsafe" designation using current evaluation guidelines (FEMA 352) and the damaged building's collapse safety. The results show that the FEMA 352 guidelines have two main shortcomings. First, the PGA=0.25g trigger for structural inspection is dangerously misleading for four of the eight frames in this study because more than 30% of the simulations that have a PGA

This book was released on 2003-03-20 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adobe, or mud brick, has been widely used as a building material in the American Southwest, including California. The vulnerability of many original adobe structures to damage or destruction from earthquakes has been of great concern. The guidelines presented here address the practical aspects of this problem and represent the culmination of 12 years of research and testing on the seismic retrofitting of adobe buildings. These guidelines can assist in the planning of seismic retrofitting projects consistent with both conservation principles and established public policy.

Download or read book Between Two Earthquakes written by Sir Bernard M. Feilden and published by Getty Publications. This book was released on 1987-10-01 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook addresses three areas of concern for the museum administrator concerning the protection of historic buildings, monuments, and archaeological sites located in seismic areas. It proposes pre-disaster measures such as taking accurate and complete documentation (photogrammetry is discussed in one of the 13 appendixes), risk awareness, planning, maintenance and inspections, etc. Second, when an earthquake strikes, the immediate emergency steps necessary to protect life and property are indicated; and after the earthquake, the strengthening of valuable cultural property (based on the Modified Mercalli Intensity Scale, also in an appendix) should be included in the general program of prevention maintenance along with the repairs discussed in detail applicable to each architectural element, and to the site as a whole.
