摘要
结构设计过程中各种判断二阶效应的理论公式都比较复杂和繁琐。以单层钢框架为例,从放大系数与稳定系数之间的关系出发,推导出的二阶效应荷载判别公式形式简单,概念清楚,应用方便。
During the course of structural design,all kinds of formulas of determining second-order effect are very complicated and miscellaneous.Taking single-layer steel frame as an example,the formula which this article gives according to the relationship between amplification coefficient and stable coefficient is simple and clear,and can be used conveniently.
