Over 200 instrumented buildings in the Los Angeles area were shook by the Whittier 1987 (Magnitude 6.1) earthquake. The data recorded in these buildings contains a wealth of information and many valuable lessons for design engineers and code writers. Six steel frame buildings from five to twenty stories in height will be investigated under this project. Using very detailed analytical models and systems identification techniques the effects of the nonstructural elements and cladding on the response of those buildings will be ascertained. The nonlinear behavior, effective periods, effective damping, torsion and the effectiveness of current modeling practices are among those items that will be considered. This study would provide a careful evaluation of the current ability to model the response of steel buildings including the effects of real and accidental torsion and irregularities.

1987年的惠蒂尔地震（6.1级）震动了洛杉矶地区200多座仪器建筑。这些建筑中记录的数据包含了丰富的信息和许多对设计工程师和代码编写者有价值的经验。在这个项目下，将调查6座5到20层高度的钢框架建筑。使用非常详细的分析模型和系统识别技术，将确定非结构元件和包层对这些建筑物响应的影响。非线性行为、有效周期、有效阻尼、扭转和当前建模实践的有效性将在这些项目中被考虑。这项研究将提供一个仔细的评估目前的能力，模拟钢结构的反应，包括实际和意外扭转和不规则的影响。
