9708627 Sause This project is part of the third phase of a coordinated program of research on Precast Seismic Structural Systems (PRESSS). The PRESSS program, funded by the National Science Foundation has two goals: (1) to develop new materials, concepts, and technologies for precast concrete construction in seismic zones; and (2) to develop comprehensive and rational design recommendations for precast concrete construction in seismic zones. The first two phases of the PRESSS program are near completion. He remaining work to be done to achieve these objectives is the testing of a large-scale precast structure design according to preliminary design recommendations and analyzed using models developed in the earlier phases of PRESSS program. The PRESSS Phase III program requires three components to achieve these objectives: (1) design studies; (2) analytical studies; and (3) superassemblage tests. Englekirk and Nakaki, Inc. and the University of Washington will conduct design studies, Leigh University will conduct analytical studies, and the University of California, San Diego will conduct experiments on the five story superassembage test structure. The objectives of the Leigh University component this project of the PRESSS Phase III program are: (1) to use nonlinear static analysis to predict the monotonic and cyclic lateral force displacement behavior of prototype buildings, and to assess this behavior of the five-story superassemblage test structure using nonlinear dynamic analysis, and assess the behavior; (3) to compare the predicted performance and the experimental performance and assess the models and methods used in the analytical prediction; and (4) to develop design recommendations for precast seismic structural systems. Analytical models of precast structures developed at Lehigh will be used. The dynamic analysis will use a set of earthquake ground motions representing various site characteristics compiled at Lehigh. Comparisons with the performance of the prototype buildings anticipated in design, and with the experimentally observed performance of the five-story superassemblage test structure will be made. The analytical studies will be carefully coordinated with the Phase III design studies and superassemblage tests.

9708627 Sause 该项目是预制抗震结构系统 (PRESSS) 协调研究计划第三阶段的一部分。 由美国国家科学基金会资助的 PRESSS 计划有两个目标：（1）开发地震区预制混凝土建筑的新材料、概念和技术； (2) 为地震区预制混凝土建筑制定全面合理的设计建议。 PRESSS 计划的前两个阶段已接近完成。 为了实现这些目标，他要做的剩余工作是根据初步设计建议测试大型预制结构设计，并使用 PRESSS 项目早期阶段开发的模型进行分析。 PRESSS 第三阶段计划需要三个组成部分来实现这些目标：(1) 设计研究； (2) 分析研究； (3)超组合测试。 Englekirk and Nakaki, Inc.和华盛顿大学将进行设计研究，利大学将进行分析研究，加州大学圣地亚哥分校将进行五层超级组合测试结构的实验。 PRESSS 第三阶段项目的利大学组成部分的目标是：（1）使用非线性静态分析来预测原型建筑的单调和循环侧向力位移行为，并评估五层超级组合的这种行为使用非线性动力分析测试结构，并评估其行为； (3) 比较预测性能和实验性能并评估分析预测中使用的模型和方法； (4) 制定预制抗震结构系统的设计建议。 将使用理海大学开发的预制结构分析模型。 动态分析将使用一组代表理海大学编制的各种场地特征的地震地面运动。 将与设计中预期的原型建筑的性能以及五层超级组合测试结构的实验观察性能进行比较。 分析研究将与第三阶段设计研究和超级组合测试仔细协调。
