武汉火车站雨棚结构由于跨度较大,施工的先后顺序和施工过程中临时支撑的设置对结构施工过程中的稳定性和施工结束时的结构位移、构件内力有较大影响。结合施工条件,设计了一套完整的施工方案,并采用有限元软件ANSYS对该施工方案进行了模拟计算分析,证实了该施工方案的可行性与可靠性。
Due to the large span of the canopy structure of Wuhan Railway Station, the order of construction and the temporary support during the construction process have a great influence on the stability in the process of construction and the structural displacement and internal force of components at the end of construction. Combined with the construction conditions, a complete set of construction scheme was designed and the construction scheme was simulated and analyzed by the finite element software ANSYS. The feasibility and reliability of the construction scheme were confirmed.
