钢筋混凝土核心筒——钢网壳结构抗震分析

REINFORCED CONCRETE CORE TUBE—STEEL NETS SHELL STRUCTURE SEISMIC PERFORMANCE ANALYSIS

通过对钢筋混凝土核心筒———钢网壳结构进行数值模拟,探讨该体系在地震作用下的协同工作性能。地震时,网壳和核心筒振动不协调,两者之间的连接处容易发生破坏。结果表明,这种上部钢网壳结构,下部钢筋混凝土结构体系,在地震力的作用下,网壳结构的变形比较明显。

Through numerical simulation to the reinforced concrete core tube-steal nets shell structure by, Discusses cooperative work performance of the system under the effects of earthquake. When the earthquake, net shell and the core tube vibration not harmonious, the connection between them prone to damage. The results show that the upper steel nets shell structure, lower reinforced concrete structure system, under the action of forces in the earthquake, nets shell structure deformation is quite obvious.
