摘要
通过对某砖混结构进行建筑隔震设计,建立该结构的有限元计算模型,研究并分析其在基本地震加速度作用下的结构反应和罕遇地震作用下的隔震层层间位移反应。计算结果表明:砖混隔震结构在设计基本地震加速度作用下,隔震结构层剪力与非隔震结构层剪力相比满足计算要求;罕遇地震作用下,隔震层最大位移满足支座最大容许位移的要求。
Through the seismic isolation design of a brick masonry building, the calculation model of the finite element of the brick masonry isolated building is established. The comparison of structural behavior under the action of basic earthquake acceleration and displacement response of isolation layer under the action of rare earthquake are researched and analyzed. The calculation results show that the comparison of the shear of isolated structure layer and non-isolated structure layer meet the requirements of calculation under the action of basic earthquake acceleration; the maximum displacement of isolated structure layer meet the requirements of maximum allowable displacement of supports under the action of rare earthquake.
