Earthquake Analysis of Buildings Including Site Properties

1985年9月的墨西哥地震清楚地表明，基础材料的动力特性对建筑体系的行为有重大影响。该项目的目的是开发计算方法和微机程序，使工程师能够对建筑物进行地震反应分析，包括场地放大效应。分析方法通过对墨西哥城受损建筑的详细研究得到了验证。对某建筑进行了维修前后的振动试验，并与计算机分析结果进行了比较。在伯克利开发的TABS程序被修改为包括一个新的基础模型，并用于几个已知基础属性的结构选择。分析结果与墨西哥地震时的观测结果进行了比较。制定了基础建模指南，可用于其他地点。最后，将现场响应程序传输到MS-DOS微型计算机上。

The September l985 Mexico earthquake clearly demonstrated that the dynamic properties of the foundation material have a significant effect on the behavior of building systems. The purpose of this project is to develop computational methods and microcomputer programs which will allow engineers to conduct earthquake response analysis of buildings, including the site amplification effect. The methods of analysis are verified by detailed studies of buildings which have been damaged in Mexico City. Vibration tests are conducted on one building before and after repair and the results are compared with computer analysis. The TABS program developed at Berkeley is modified to include a new foundation model and used for several structures selected in which the foundation properties are known. Results of analysis are compared with observed behavior during the Mexico earthquake. Foundation modeling guidelines are developed which can be used for other sites. Finally, the site-response program is transferred to the MS-DOS microcomputers.
