摘　　要：为了研究扭曲柱工程中的结构设计难点,采用SAP2000,PMSAP和EPDA等软件进行了扭曲柱工程中的楼板应力分析和屈曲分析,同时与缩尺模型地震模拟振动台试验结果进行了对比。结果表明:斜柱及斜撑构件竖向角度变化处会产生较大水平分力,水平分力会传递给与其相连的梁、板。设计时,此区域采用型钢混凝土梁,适当增大此区域楼板配筋,可以显著提升结构整体性能。In order to study the structural design difficulties in twisted column engineering, softwares such as SAP2000, PMSAP and EPDA were used to carry out the stress analysis and buckling analysis of the floor in twisted column engineering. At the same time, the results were compared with the scale model seismic simulation shaking table test results. The results show that oblique columns and diagonal bracing members will produce a large horizontal force when the vertical angle changes, and the horizontal force will be transmitted to the connected beams and plates. This area adopts steel-reinforced concrete beams, and appropriately increasing the floor reinforcement in this area can significantly improve the performance of overall structure.
