Seismic Behavior of Multiple-Connection Flat-Slab Assemblies

本研究的主要目的是评估低- 到墨西哥地震中受损的中高层平板建筑 1985年9月19日地震，并检查美国是否足够。 类似建筑物的抗震设计程序。 信息 介绍了墨西哥板柱连接的设计和施工实践， 与墨西哥合作调查员合作收集的。 的 这些连接件的强度、刚度和设计特点是 与美国建筑规范规定的相比。 十二大规模 多节点和单节点板柱组合体 根据美国的实践设计并在实验室进行测试， 评估其在非线性响应范围内的性能， 地震荷载 测试组件包括具有和 没有边梁。

The main objective of this study is to evaluate the performace of low- to medium-rise flat-slab buildings damaged during the Mexican earthquake of September 19, 1985, and to check the adequacy of U.S. procedures for the seismic design of similar buildings. Information on Mexican design and construction practive for slab-column connections is collected incooperation with the Mexican co-investigator. The strengths, stiffnesses, and design features of these connections are compared to those specified by U.S. building codes. Twelve large-scale multiple-connection and single-connection slab-column assemblies are designed according to the U.S. practice and tested in the laboratory to evaluate their performance into the nonlinear range of response under earthquake-type loading. The test assemblies include slabs with and without edge beams.
