摘要
介绍了位于天津的满月塔的工程概况并提出了圆钢拉杆预应力的结构体系。用ANSYS建立了满月塔的三维有限元模型。通过静力分析设计了拉杆、梁以及柱构件。针对预应力的施加方法设计了新型的拉杆连接节点和梁贯通型梁柱节点。对满月塔进行了模态分析和地震响应分析,并通过与悬臂梁模型的对比分析了满月塔的动力特性。
General situation of the full-moon tower is introduced, and the structural system with prestressed tension rods is put forward. Using ANSYS program,the 3D model of the tower is established. The tension rod, beam and column components are designed based on static analysis. According to the application method of prestress, new types of tension rod joints and beam-through beam-column joints are designed. Mode and earthquake response of analysis are carried out on the structure. Compared with the cantilever model, the dynamic characteristic is researched.
