摘　　要：文章以某带斜柱的框架-核心筒结构为例,通过对该结构进行多遇地震下的弹性计算和罕遇地震下的弹塑性计算,分析了结构整体和斜柱的受力性能;分析结果表明,在大震作用下,结构整体及斜柱具有较好的承载和变形能力,能够达到期望的性能指标;通过抗震性能分析找出抗震薄弱构件,并采取有针对性的构造加强措施以指导结构设计,可供类似工程参考。Taking a frame-core tube structure with inclined column as an example ,and through per-forming the elastic calculation under frequent earthquake and the elastic-plastic calculation under rare earthquake ,the bearing capacities of the whole structure and the inclined column are analyzed .The results show that the w hole structure and the inclined column have good bearing and deformation ca-pacities under the rare earthquake and meet the desired performance indicators . The weak seismic member is found out by seismic analysis to guide the structural design .The presented study can pro-vide a reference for similar projects .
