中文摘要:
      钢框架壁板由于在宏观上参与了整体建筑结构的受力,为钢框架构件承担部分外荷载,使得壁板结构在受力性能方面需要进一步改善。加劲肋壁板可以保证其与外框架的连接状况较好,改善整体构件的受力性能。为此,提出钢框架加劲肋壁板结构的受力失稳性能研究。采用动力学分析方法计算壁板结构位移值,依照位移值大小判断壁板结构是否处于稳定状态,获取壁板结构稳定性。利用实例测试分析钢框架加劲肋壁板结构的受力失稳性能,发现滞回曲线形状拥有梭形滞回曲线的特点,整个结构受力后具有塑性变形性能与抗震性能;骨架曲线反映出实验试件承载力支持第一阶段壁板结构弹性设计所需且提供第二阶段弹塑性抗震设计所需以及延性要求,本文检测模型能够判断钢结构建筑壁板结构失稳性。
英文摘要:
      The mechanical properties of the panel structure must be improved because the steel frame panel contributes to the stress of the whole building structure and bears some part of the external load of the steel frame members. The rib-stiffened panel can achieve a good connection with the outer frame and improve the mechanical performance of the whole structure. Therefore, the mechanical instability performance of the steel frame rib-stiffened panel structures is investigated in this study. Here, the dynamic analysis method is used to calculate the displacement of the panel structure. The stability of the panel structure can be judged according to the displacement value; thus, the stability of the panel structure can be ensured. The example test results denote that the hysteretic curve shape exhibits the characteristics of the shuttle hysteretic curve, and the whole structure exhibits plastic deformation performance and aseismic performance after being subjected to tension; the skeleton curve denotes that the bearing capacity of the test specimens can satisfy the requirement of elastic design with respect to the wall panel structure in the first stage and achieve the elastic-plastic seismic design and ductility requirements in the second stage. The proposed detection model can judge the instability of the steel panel structures.
