摘要
在确定地震波的最不利输入方向的结构地震分析中 ,最困难的就是确定最不利输入方向的标准 .为此 ,在研究和评价基础上 ,对用屈服面函数判断得到截面最不利受力状态和用截面主轴弯矩最大值来设计或检算这两种方法进行了进一步的探讨 。
The most difficult problem is to determine the standard of critical angle in seismic analysis of complicated structures.Based on reviewing the predecessors' work on this problem,two methods,which are used to judge critical phase of sectional force by yield surface function or maximum moments of two section principal axies and to disign or examine the structure,are discussed deeply in this paper.The range of safety coefficients is promoted under the case of superposed static loads.
