项目摘要
This project will closely analyze structural deficiencies that lead to total collapse and non-repairable damage of reinforced concrete buildings due to earthquakes. There will be specific concentration on buildings that have or can benefit from using shear walls. The main focus of this project is to study in detail the series of failures that lead to total loss, and to evaluate the economic benefits of adding shear walls. Research will be conducted at GNS Science located in Lower Hutt, under the mentorship of Dr. S.R. Uma, a renowned expert in the field of earthquake engineering and structural response. In depth engineering reports will be made available that focus on structural failure details from the 2010 and 2011 Christchurch earthquakes. The outcomes of this project will lead to improved recognition of dangerous buildings, improved accuracy of computer modeling, and greater understanding of the economic benefits of retrofitting dangerous structures. New Zealand is an optimal location to study seismic performance because of the Christchurch earthquakes which destroyed many structures and because of the detailed engineering reports that have been produced since. This project will help develop nonlinear structural analysis skill and technique to accurately simulate localized failures in concrete structures. Nonlinear computer simulation of structures is a still-developing tool for engineers to study how a building behaves as a whole under dynamic loading. In the United States, nonlinear modeling techniques are being used to evaluate the seismic risk of structures that were built before modern buildings codes and structural analysis tools. Even with recent advances in nonlinear modeling techniques, it is difficult to accurately simulate the total collapse of buildings like the Pyne Gould building in Christchurch which killed 182 people in 2011, because of the multitude of smaller local failures that lead to the global collapse. Understanding the deficiencies of concrete structures and taking steps to retrofit them must allow for, at a minimum, life-safety of building occupants, minimal loss of building functionality, and economic viability. By improving understanding of retrofit options and trade-offs, this project will inform decision-making about the identification and improvement of dangerous RC shear wall structures in the U.S. and around the world. This award is funded in collaboration with the Royal Society of New Zealand.
该项目将密切分析导致钢筋混凝土建筑物因地震而完全倒塌和不可修复损坏的结构缺陷。将有具体的集中在建筑物,有或可以受益于使用剪力墙。本项目的主要重点是详细研究导致总损失的一系列破坏,并评估增加剪力墙的经济效益。研究将在位于Lower Hutt的GNS Science进行,由S.R.博士指导。他是地震工程和结构反应领域的著名专家。将提供深入的工程报告,重点介绍2010年和2011年基督城地震的结构故障细节。该项目的成果将提高对危险建筑的识别,提高计算机建模的准确性,并更好地了解改造危险结构的经济效益。新西兰是研究抗震性能的最佳地点,因为基督城地震摧毁了许多建筑物,而且此后产生了详细的工程报告。这个项目将有助于发展非线性结构分析技能和技术,以准确地模拟混凝土结构的局部故障。结构的非线性计算机模拟是一个仍在发展的工具,工程师研究如何作为一个整体的建筑物在动态载荷下的行为。在美国,非线性建模技术正被用于评估在现代建筑规范和结构分析工具之前建造的结构的地震风险。即使非线性建模技术取得了最新进展,也很难准确模拟建筑物的整体倒塌,例如2011年在基督城造成182人死亡的Pyne Gould大楼,因为许多较小的局部故障导致全球倒塌。了解混凝土结构的缺陷并采取措施对其进行改造,必须至少考虑到建筑物占用者的生命安全、建筑物功能的最小损失和经济可行性。通过提高对改造方案和权衡的理解,该项目将为美国和世界各地危险RC剪力墙结构的识别和改进决策提供信息。该奖项是与新西兰皇家学会合作资助的。
