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.

本研究的主要目的是评估 1985 年 9 月 19 日墨西哥地震中受损的中低层平板建筑的性能，并检查美国类似建筑抗震设计程序的充分性。 有关墨西哥板柱连接设计和施工实践的信息是与墨西哥联合调查员合作收集的。 这些连接的强度、刚度和设计特征与美国建筑规范规定的进行比较。 根据美国实践设计了12个大型多连接和单连接板柱组件，并在实验室进行了测试，以评估其在地震荷载下非线性响应范围内的性能。 测试组件包括带边梁和不带边梁的板。
