屈曲约束支撑加固框架核心筒结构的抗震分析
Seismic analysis of frame core tube structure reinforced by buckling restrained brace
摘要
Abstract
The random function expression of non-stationary ground motion processes was used,the Amin-Ang intensity modulation function and the Kanai-Tajimi power spectrum model were selected to generate a set of 144 representative samples of random seismic motion.This method only used one basic random variable to simulate the generation of hundreds of random seismic motion samples,which could achieve high engineering accuracy.Two types of buckling restrained braces(BRB),herringbone and V-shaped,were selected to reinforce a frame core tube structure in the Beichuan area of Sichuan Province,which was affected by the update of seismic codes.The seismic performance and energy information of the original structure and its two reinforced structures were analyzed.The results showed that the seismic reinforcement effect varied with the same layout position and different support forms.This method is far superior to the simulation effect of traditional artificial random ground motion.关键词
