针对石家庄省会体育中心体育场结构方案,取三种计算模型进行分析比较:下部混凝土结构分缝单独计算、上部钢结构罩棚单独计算模型;下部混凝土结构分缝与上部钢结构罩棚不设缝整体计算模型;下部混凝土结构分缝与上部钢结构罩棚分缝分段整体计算模型。同时考虑抗震性能化设计,针对结构构件重要程度的不同区别对待。而且体育场的平面尺寸较大,由于罩棚和看台均处于露天环境,温度应力需要引起足够重视。
According to the structure plan of the stadium in Shijiazhuang provincial capital sports center, three calculation models are adopted to analyze and compare: the lower part of the concrete structure is calculated separately and the upper part of the steel structure canopy is calculated separately; the lower part of the concrete structure and the upper part of the steel structure ; The overall calculation model of the sub-section of the lower concrete structure and the sub-section of the shed of the upper steel structure. At the same time consider the seismic performance of the design, the importance of different structural components for different treatment. And the larger the size of the stadium, due to the shed shed and stands are in open air environment, temperature stress needs to be given enough attention.
