摘要
攀岩馆的主体结构为不规则立方体网格结构,存在扭转不规则、楼板不连续、竖向构件不连续等问题,也是规范未列入的结构类型。通过周期比、扭转位移比、剪重比、应力比等参数的分析,验证了攀岩馆的受力特性;并采用屈曲分析计算了结构整体的弹塑性极限承载力,研究了结构的塑性发展机制。同时,通过罕遇地震弹塑性时程分析研究了整体结构在大震作用下的损伤情况,研究表明该结构体系可以成立。
The main structure of the climbing gym is an irregular cube grid structure, which has problems such as irregular torsion, discontinuous of floor and discontinuous of vertical members. It is also a structural type not listed in the specification. The mechanical characteristics of the climbing gym are verified through the analysis of parameters such as period ratio, torsional displacement ratio, shear-gravity ratio and stress. The elastic-plastic ultimate bearing capacity of the whole structure is calculated by buckling analysis, and the plastic development mechanism of the structure is studied. At the same time, the damage of the whole structure under the action of rare earthquakes is studied through the elastic-plastic time-history analysis of rare earthquakes. The results show that the structure system can be established.
