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。
Using MIDAS to compare and analyze the single steel structure model of Shanxi Science and Technology Museum and the static calculation results of the steel and concrete model, and the difference of the steel structure responses in the two models under the earthquake load. In the steel structure and concrete overall design checking, The seismic response of the steel structure section increases greatly compared with the seismic response of the single steel structure model. The plastic time-history analysis of large earthquakes gives the seismic response of the whole structural model under the action of strong ground motion acceleration recording and the state of the out-hinged hinge. The structure still has a significant reserve of strength and deformation under the action of a large earthquake. The design goal of repair. The non-linear buckling analysis method of ANSYS structural system is used to analyze the overall stability of the steel structure with different models. The continuous sliver contribution to the lateral stability of the plane truss is quite obvious.
