摘　　要：目的研究异型柱钢筋混凝土高层框架结构危险部位的受力情况,以及结构整体的静力和动力分析。方法应用ANSYS有限元程序对沈阳五爱市场三期工程的一座20层钢筋混凝土异形柱框架结构的四星级酒店进行建模、计算并进行分析。结果得出该结构在静力荷载下的位移和内力,并进行了模态、地震模拟,得出了结构的前6阶频率、振型和地震作用下节点的时间历程曲线。结论有限元软件可以模拟、分析异型柱钢筋混凝土框架结构,为y型柱设计提供了理论依据。Analysis of the RC frame with special shaped columns of Wuai Market was performed tentativefy using the ANSYS finite element software. The displacements and internal forces under static and dynamic bad were achieved At the same time, a modal analysis of the RC frame was conducted and both the proceeding 6 frequencies and the vibration patterns were obtained. The time-history curve under the action of earthquake can also be obtained. The results are compared so that the dynamic properties of high building can be obtained ,which provides a foundation for further study of the mechanicai properties of frame structure. The study provides a reference for the design of simiiar projects.
