| 摘 要： | 利用大型结构分析软件ETABS建立了包含和不包含钢管支撑的钢筋混凝土框架计算模型,分别采用底部剪力法、反应谱分析和时程分析3种方法对2种模型进行了对比计算分析.结果显示:在纯钢筋混凝土框架结构中合理设置钢支撑,可以达到增加框架结构的侧向刚度,明显降低结构侧向变形,而基底剪力仅略有增加,且可实现多道设防的效果.

| Abstract: | Computer models of frame with steel - bracing are made,seismic - performance of the models are calcaulated by adopting base - shear method,spectrum analysis,and time history analysis based on ETABS. The results show that including steel - eccens into models will increase story - stiffness,decrease top - point displacement of frame structure significantly,but the base - shear increase a little,reach the require of more defences in seismic concept design of buildings. |
