摘要: 根据历年来的地震震害调查显示,四川地区古建筑木结构连接部分的典型震害为柱脚滑移。为预测古建筑木结构在地震作用下的柱脚滑移量,判定其震害的损伤度,以柱础连接为对象,将柱础连接简化为水平弹簧和转动弹簧,建立了柱础动力学方程;并在求解过程对不规则的地震激励进行简化,代以峰值激励进行作用,引入等效刚度和修正系数对方程进行修正,从而提出了不同激励下的最大柱脚滑移量和最大结构倾斜度解析表达式。

Abstract: According to the investigation of earthquake damage over the years, the slippage of the column foot is a typical damage of the column base connection part of ancient timber structures in Sichuan areas. In order to predict the slippage of the column foot and determine the degree of earthquake damage of ancient timber structures, the column base connection is chosen as the research object. The connecting part is simplified into horizontal and rotating springs, then the dynamic equations of structures are established accordingly. In the solution process, the irregular seismic excitation is simplified, and the peak excitation is used as the constant input. The equivalent stiffness and the correction coefficient are introduced to modify the equation and the solution results, and finally the expressions of the slip distance of the column foot, the maximum slip distance and the maximum inclination angle of the column are obtained.
