某商业综合楼结构竖向设置斜柱,结构体系复杂,应用ANSYS有限元分析程序对其进行计算分析。通过计算得到了结构静荷载和动荷载作用下的内力和位移,以及结构的频率和振型特点。分析表明:与常规结构相比,斜撑及与之相连的构件受力明显增大,X向刚度要小于Z向刚度,结构振动的控制方向为X方向。 A commercial building structure vertical inclined column, the structural system is complex, the application of ANSYS finite element analysis program to calculate and analyze. The internal forces and displacements caused by the static and dynamic load of the structure are obtained by calculation, and the characteristics of the structure frequency and mode shape are also obtained. The analysis shows that compared with the conventional structure, the stress on the bracing and its connected components increases obviously, the X direction stiffness is less than the Z direction stiffness, and the control direction of the structure vibration is the X direction.
