结构物对随机地震激励的响应分析

本文对结构物在随机地震激励下的弹性响应做了分析.以框剪体系的结构物为对象,导出了实用计算公式,并编制了FORTRAN语言程序及实例验算.根据结构物的使用要求,赋以不同的动力可靠性(首次偏移概率),从而可以得出体系的最大水平位移的包络线及内力变化规律.     

AN ANALYSIS ON RESPONSE OF STRUCTURE TO RANDOM EARTHQUAKE EXCITATION

In this paper the response of elastic structure to random earth-quqke excitation isanalysed.For a frame-wall system. practical calculating formulas are derived and aprogram in FORTRAN language is made. The program is checked with a numericalexample. The envelope of the lateral displacement of the system and the variation regularityof the internal forces are determined from given values of dynamic reliability (firstexcursion probability) based on the requirement of the operation of the structures.
