This book was released on 2008 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seismic vulnerability of nonstructural components and equipment with their expensive recovery and/or replacement costs has been demonstrated during past earthquakes. The limited data collected from past earthquakes and the relatively scarce research in this field are not sufficient to completely characterize the seismic behavior of nonstructural components and develop effective mitigation measures. This is a serious deficiency considering that the investment in nonstructural components and building contents is far greater compared to structural components and framing. In order to address these deficiencies and to better understand the seismic behavior of nonstructural components, the University at Buffalo Nonstructural Component Simulator (UB-NCS), composed of a two-level testing frame, has been commissioned to subject nonstructural components to realistic full-scale floor motions. The UB-NCS testing platform can subject nonstructural systems to 3g acceleration, 100 in/s velocity and " 40 in displacement amplitudes. This new equipment provides improved experimental capabilities for more realistic qualification testing and fragility assessment of nonstructural systems. Full-scale, anchored or self-supported equipment and building contents, with attachment points at one or two consecutive building levels can be tested. Most important, equipment and combined nonstructural systems that may be sensitive to both accelerations and/or interstory drifts can be rigorously evaluated under realistic loading conditions to evaluate interdependencies among nonstructural components and the interaction with the primary structural system. The actual testing capabilities and limitations of the UB-NCS were evaluated through an extensive series of tests. The fidelity of the testing facility to reproduce, under controlled laboratory conditions, full-scale seismic floor motions expected in multistory buildings, and other random and harmonic motions was demonstrated. In order to archive a satisfactory equipment performance, an off-line compensation procedure was developed and recommended for testing of full-scale nonstructural specimens. In order to more broadly assess the seismic performance of nonstructural components, systems and equipment, independent of building or ground motion, an innovative set of testing protocols taking full advantage of the UB-NCS testing capabilities is proposed. The proposed protocols complement, and in some cases extend, the capabilities of current nonstructural qualification procedures such as the AC156 seismic qualification protocol and the fragility testing methodologies proposed in FEMA 461. In particular, new capabilities are provided for testing nonstructural systems with multiple attachment points that may be displacement and/or acceleration sensitive by simultaneously applying interstory drifts and absolute floor accelerations. The unique testing capabilities of the UB-NCS are demonstrated through a series of experiments assessing the seismic performance of a full-scale composite hospital emergency room containing typical nonstructural components such as architectural finishes, piping systems and life support medical equipment. In these tests, the seismic performance of individual nonstructural components and medical equipment was evaluated as well as the dynamic interactions and interdependencies between nonstructural systems and contents. The seismic behavior of displacement sensitive partition walls and acceleration sensitive wall mounted patient monitors were closely examined. The input motions for these tests included the loading protocol developed as part of this dissertation and simulated building floor motions.

Book excerpt: Façade design is a challenging task, in which multidisciplinary issues and aspects should be optimally considered and addressed. This is especially the case of building façades exposed to seismic events, impacts, or fire. Special attention and major efforts are required for the detection and application of new technologies in the generation of modern, adaptive façade systems. This book presents a selection of research contributions to provide a comprehensive overview of façade design. It discusses the experimental analysis and numerical investigation of existing or traditional façades, as well as the development and optimal application of new technologies for modern adaptive façades and building envelopes.

Book Synopsis National Earthquake Resilience by : National Research Council
Download or read book National Earthquake Resilience written by National Research Council and published by National Academies Press. This book was released on 2011-09-09 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States will certainly be subject to damaging earthquakes in the future. Some of these earthquakes will occur in highly populated and vulnerable areas. Coping with moderate earthquakes is not a reliable indicator of preparedness for a major earthquake in a populated area. The recent, disastrous, magnitude-9 earthquake that struck northern Japan demonstrates the threat that earthquakes pose. Moreover, the cascading nature of impacts-the earthquake causing a tsunami, cutting electrical power supplies, and stopping the pumps needed to cool nuclear reactors-demonstrates the potential complexity of an earthquake disaster. Such compound disasters can strike any earthquake-prone populated area. National Earthquake Resilience presents a roadmap for increasing our national resilience to earthquakes. The National Earthquake Hazards Reduction Program (NEHRP) is the multi-agency program mandated by Congress to undertake activities to reduce the effects of future earthquakes in the United States. The National Institute of Standards and Technology (NIST)-the lead NEHRP agency-commissioned the National Research Council (NRC) to develop a roadmap for earthquake hazard and risk reduction in the United States that would be based on the goals and objectives for achieving national earthquake resilience described in the 2008 NEHRP Strategic Plan. National Earthquake Resilience does this by assessing the activities and costs that would be required for the nation to achieve earthquake resilience in 20 years. National Earthquake Resilience interprets resilience broadly to incorporate engineering/science (physical), social/economic (behavioral), and institutional (governing) dimensions. Resilience encompasses both pre-disaster preparedness activities and post-disaster response. In combination, these will enhance the robustness of communities in all earthquake-vulnerable regions of our nation so that they can function adequately following damaging earthquakes. While National Earthquake Resilience is written primarily for the NEHRP, it also speaks to a broader audience of policy makers, earth scientists, and emergency managers.

Book excerpt: Gilt immer noch, dass ein Bauwerkseinsturz der beste Lehrmeister für den Fortschritt des Bauens ist? Oder, anders formuliert: Ist Bauen dann, wenn wir das Bewährte verlassen und Neues wagen, "Experimentieren"? Über die Ursache von Schadensfällen und Einstürzen, die oft mit dem Verlust von Menschenleben verbunden sind, wird nicht gern öffentlich gesprochen. Aber aus Fehlern kann man lernen. Die Lehren und Erfahrungen aus den Schadensauswertungen führen zu mehr Sicherheit und oft zum Innovationsschub. Die Kenntnis der Schadensursachen ist Voraussetzung für ihre zukünftige Vermeidung. Mit diesem Buch liegt eine systematische Zusammenstellung von über 400 Versagensfällen vor, die in besonderer Weise betrachtet werden: Sie werden nach dem Zeitpunkt ihres Auftretens im Lebenszyklus der Brücke, z. B. im Bauzustand oder im Betrieb, und nach den Schadensereignissen, z. B. Anprall oder Erdbeben, geordnet. Die wichtigsten Ursachen sind: menschliches Versagen, mangelnde Aussteifung, Materialversagen oder Überlastung. Es werden vorwiegend Brückeneinstürze, die in der Literatur wenig oder nach dem Urteil des Verfassers nicht vollständig oder nicht zutreffend behandelt sind, ausführlich analysiert. Mit Akribie gesammelt, kompetent und exzellent aufgearbeitet und mit Mut präsentiert, ergibt dies eine unverzichtbare Erkenntnisquelle für jeden Bauingenieur in der Praxis und für das Studium. Ein Katalog von Regeln wurde erstellt. Seine Beachtung kann helfen, Fehler bei Entwurf, Planung und Ausführung zu vermeiden.
