呼和浩特东站站台雨棚结构设计与分析

摘要

Taking the platform canopy at Hohhot East Station as a project case, this paper introduces the design process of a beam string structure ( BSS). Using SAP 2000 and ANSYS finite element analysis software, the whole BSS and the BSS members were analyzed respectively, and both calculation results could accord well with each other. Combined with the characteristics of beam string structure, the feasible hoisting scheme were put forward which could ensure the safety of beam string structure in the processes of tensioning and hoisting. Finally the bearing joint of the beam string structure was analyzed, and a new type of bearing joint was designed. Through numerical simulation analysis on the joint, it is concluded that the design can meet the relevant requirements.%以呼和浩特东站站台雨棚为工程案例,详细介绍大跨张弦梁的设计过程.应用SAP2000和ANSYS有限元分析软件,分别对张弦梁整体结构和单榀构件进行分析,两者计算结果吻合较好;结合工程特点,提出合理的吊装方案,确保了张弦梁张拉和吊装过程的安全.最后对张弦梁支座节点进行了分析,设计出新型支座节点,并对节点进行数值模拟分析,结果满足要求.
