质量和刚度非对称结构在水平双向地震作用下的随机反应分析

Analysis of Random Response of Structures with Non-symmetry Mass and Stiffness Distribution under Earthquake Along Two Horizontal Directions

本文在水平地面运动存在两个互不相关主轴假设下,给出了适用于平面刚度无限大的多层建筑的有量纲和无量纲随机反应公式,对影响质量和刚度非对称多层建筑地震反应的一些重要因素做了较详细的分析。

This paper gives the dimensional and non-dimensional random earthquake response formulas of multi-story structures with rigid floorslabs and non-symmetry mass and stiffness distribution and studies some important factors which influence the earthquake response of these structures under the condition of the ground movement in which there are two unrelated principal axes of ground movement.
