9416530 Tajirian The objectives of this project are to study the response of base- isolated structures using computer simulation and to evaluate their current design code provisions in light of the strong-motion data obtained during the Northridge earthquake. The response of four isolated structures located in Los Angeles area instrumented by the California Strong Motion Instrumentation Program SMIP) will be estimated using simplified techniques and recorded ground-motion data, and compared with the recorded structural responses. In addition, a detailed analysis of the University of Southern California Hospital structure will be carried out. A three- dimensional, non-linear model of this building with a simplified soil-structure interaction model will be created and used to the assessment of the predictability of the response of base-isolated structures subjected to moderate ground motions, and the effects of soil-structure interaction in the response of base-isolated structures. This is a Northridge Earthquake Project.

9416530 Tajirian本项目的目标是使用计算机模拟研究基础隔震结构的响应，并根据北岭地震期间获得的强震数据评估其当前的设计规范规定。 采用简化的方法和记录的地震动数据对位于洛杉矶地区的四个隔震结构的响应进行了估算，并与记录的结构响应进行了比较。 此外，还将对南加州大学医院的结构进行详细的分析。 将建立该建筑物的三维非线性模型和简化的土壤-结构相互作用模型，并用于评估基础隔震结构在中等地面运动下的响应的可预测性，以及土壤-结构相互作用对基础隔震结构响应的影响。 这是北岭地震项目。
