[摘要]应用MIDAS对比分析了山西科技馆单体钢结构模型与钢结构和混凝土整体模型静力计算结果,以及地震荷载作用下两种模型中钢结构响应的差异,在钢结构与混凝土整体设计验算中,钢结构部分的地震响应与单体钢结构模型的地震响应相比增长很大。大震弹塑性时程分析给出了整体结构模型在强震地面运动加速度记录作用下的地震响应以及出铰状态,结构在大震作用下仍具有显著的强度与变形能力储备,达到大震可修的设计目标。应用ANSYS结构体系非线性屈曲分析方法以不同模型对比分析了钢结构的整体稳定性,其中连续檩条对平面桁架侧向稳定性贡献相当明显。

Abstract:The steel structural model of Shanxi Provincial Science Museum is analyzed with MIDAS software, and compared with the analysis result of the combined steel-concrete structure model of the museum, subject to the static load and the seismic load respectively. In order to obtain the differences of the structural response from these two models. The results show that the steel structure seismic response in combined structure model increases faster than that of the steel structural model. The seismic response of the ground acceleration and the plastic hinge during the ultimate earthquake are recorded by conducting the elastic-plastic time-history ultimate seismic analysis, showing that the structure owns the apparent strength and the displacement capacity saving, and reaches the objective of rehabilitation after ultimate seismic. The structural steel overall stability is analyzed by using the nonlinear buckling analysis in ANSYS package software for the different models, illustrating that the continuous purlin clearly contributes a lot to the lateral stability of the in-plane truss.
