Evaluation of Tilt-Up-Wall Structural Systems Affected by the Whittier Narrows Earthquake of October 1, 1987

倾斜结构体系是一种流行的商业和工业建筑结构体系。在地震期间，关于倾斜墙系统性能的数据缺乏。这个研究项目建立在早期研究调查收集的数据基础上。研究项目包括建筑分类、建筑分析以及研究结果与实际观测到的惠蒂尔海峡地震中建筑性能的相关性。研究结果将有助于实践工程师设计稳定、经济、轻便、具有足够强度和延性的斜上墙建筑。结论将适用于地震带，但也可以应用于其他侧向载荷，如极端风。

Tilt-up structural systems are a popular construction system for commercial and industrial buildings. There is a lack of data on the performance of tilt-up wall systems during earthquakes. This research projects builds on data collected in earlier research surveys. The research project includes building classification, building analyses, and correlation of research results with actual observed building performance during the Whittier Narrows earthquake. The results of the research project will be useful in aiding practicing engineers in the design of stable, economic, lightweight tilt-up-wall buildings with adequate strength and ductility. The conclusions will be applicable to seismic zones but can also be applied to other lateral loadings such as extreme winds.
