地铁上盖钢框架整体结构的抗侧力性能试验分析
|
摘要
传统地铁上盖钢框架整体结构的性能分析角度单一,忽略了对框架结构的荷载与位移之间的关系分析,导致分析结果的可靠性较低,对地铁上盖钢框架整体结构的抗侧力性能进行试验分析。利用某地铁的上盖建筑所采用的结构设计和工程概况等信息数据,对地铁上盖钢框架结构的抗侧力数据进行计算,根据计算结果分别从框架刚度、侧向刚度、荷载与位移之间的关系等方面对地铁上盖钢框架整体结构的抗侧力性能进行试验分析。试验结果表明,所提方法可以较好的对框架刚度、侧向刚度理论分析结果的正确性进行验证。在建设地铁上盖时,它的承受荷载和层间角位移最好要小于它的极限荷载和最高位移值。试验分析结果为地铁上盖建筑提供了良好的参考依据。
The performance analysis angle of the traditional steel frame structure is single and the relationship between the load and the displacement of the frame structure is neglected, which leads to the low reliability of the analysis results. In this paper, the lateral force resistance of the whole structure of steel frame with top cover of subway is tested and analyzed. Based on the information data of structural design and engineering survey of the upper cover building of a subway, the lateral force data of the steel frame structure are calculated. According to the calculation results, the frame stiffness and lateral stiffness are calculated, respectively. In this paper, the lateral force resistance of the steel frame structure with steel cover is tested and analyzed in terms of the relationship between load and displacement. The experimental results show that the proposed formula The results of theoretical analysis of frame stiffness and lateral stiffness can be verified by the method. In the construction of the upper cover of subway, its bearing load and interstory angular displacement should be less than its limit load and maximum displacement value. The result of the test provides a good reference for the construction of the upper cover of the subway.
