摘要
在高层建筑结构计算中，若结构的轴力较大而侧向刚度较小时，其二阶效应不可忽略。针对框一剪结构的二阶分析，本文推导出了一个非常简明的基本微分方程，在形式上，此方程只是一阶理论时框一剪结构基本微分方程的简单推广。此方程在应用上特别简便，此外，方程中的“二阶效应系数”正确反映了产生二阶效应的诸因素的影响。文末附有算例。
In the analysis of high-rise building structures, the second order effect is not negligiblewhen the structural axial force is excessive and the lateral rigidity is weak. In this paper, a verybrief basic differential equation is derived for second order analysis of frame-shear wallstructures. In form, it is merely a simple extension of the basic differential equation of frameshear wall structure in first order theory. This equation is very convenient in practical use. Inaddition, 'second order effect coefficient' correctly reflectS affection of various factorsproducing second order effect. An example is provided at the end of the paper.
