摘要

在错层框架结构中,错层高度和错层结构形式是影响结构错层区域受力性能的两大主要因素。本文针对常见的规则错层及对称变维错层结构,通过弹性和弹塑性时程分析,研究了在多遇及罕遇地震作用下不同错层高度的错层结构错层区域所受剪力的变化规律,进一步简化错层区域剪力的计算公式,提出了考虑结构非线性影响的这两类错层结构错层区域剪力的增大系数。

Abstract

In the split-level structure, the split-level height and form are the main factors influencing the loading capability of split-level region. In this paper, the regular split-level and symmetric trans-dimensional structure with uniform mass distribution were analyzed. Under frequent and rare earthquake excitations, the changing rule of shear force of the split-level region with different split-level height was studied through elastic-plastic time-history analysis. The shear force equation for the split-regen was further simplified. Considering the nonlinear influence, the magnifier of shear force for the split-level region was proposed.
