摘要
利用ANSYS建立的6个空间有限元模型分析了带加强层框筒结构的侧向位移。通过对不同假设下建立的有限元模型的计算得到了框架柱弯曲刚度,普通框架梁等因素在带加强层高层结构抗侧移的贡献情况。讨论了各种计算模型的特点及分析结果的精确性。从三维有限元分析结果看出,在设计带加强层的高层建筑结构时必须用考虑楼层梁和框架柱抗弯作用的计算模型来控制侧向位移。
The sideway of a frame-tube structure is analyzed by the software of ANSYS with space finite element model. By the calculation under the different models which are constructed by 6 different assumptions the effects to reduce sideway which were supplied by stiffness of columns and frame beams can be got. Characters of each model and the accuracy of their results are discussed in this paper. The results of space finite element analysis indicate that when designing a structure with outrigger it's necessary to control the sideway using a calculate model considered the effects of stiffness of columns and frame beams.
