某砖混住宅轻钢结构加层抗震设计研究

摘要

为了探讨利用无比轻钢加层后结构的抗震性能，以无比轻钢结构加层后的某砖混结构为研究对象，对无比轻钢结构提出了一个简化的计算模型．采用底部剪力法计算出加层后在水平地震作用下各层地震剪力，运用结构力学求解器计算出加建层结构各柱的内力，然后对柱的承栽力作了验算．结果表明，在水平地震作用下各柱没有发生破坏．因此，无比轻钢结构的抗震性能好，具有良好的应用前景．%In order to investigate seismic performance of adding storey structure with web light-weight steel, based on research object of adding storey with web light-weight steel on brick-concrete structure, a simplified calculation model is put forward with web light-weight steel. The earthquake shear forces of each floor was calculated with equivalent base shear method, and after figuring out the internal forces of the column of the adding storey with SM Solver, checking calculation for the capacity of the columns has been finished. The result shows that columns are not destroyed under horizontal earthquake action. Therefore, WEB light steel has good seismic performance; it will be used in more storey-adding projects in the future.
