［摘要］為了研究扭曲柱工程中的結(jié)構(gòu)設計難點，采用SAP2000，PMSAP和EPDA等軟件進行了扭曲柱工程中的樓板應力分析和屈曲分析，同時與縮尺模型地震模擬振動臺試驗結(jié)果進行了對比。結(jié)果表明：斜柱及斜撐構(gòu)件豎向角度變化處會產(chǎn)生較大水平分力，水平分力會傳遞給與其相連的梁、板。設計時，此區(qū)域采用型鋼混凝土梁，適當增大此區(qū)域樓板配筋，可以顯著提升結(jié)構(gòu)整體性能。

Abstract: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.
Keywords:over-limit high-rise building; oblique column; twisted column; floor stress; buckling analysis
