【摘要】 参照框架-剪力墙协同工作模型的基本思路,建立了钢框架-混凝土核心筒混合结构的二维弹塑性地震反应分析模型和计算方法.然后在此平面二维分析模型的基础上,加入钢框架和混凝土核心筒之间的横向钢梁的空间约束作用.对于钢框架和核心筒之间的横向梁的空间效应,可以用弹性的竖向弹簧和转动弹簧来模拟,在考虑竖向弹簧的作用的基础上,再考虑转动弹簧的作用,建立了该混合结构的拟三维弹塑性地震反应分析模型及相应的计算方法,最后编制相应单元程序,与大型结构非线性动力反应分析程序 DRAIN -2D 相结合,给出该混合结构的拟三维弹塑性地震反应分析方法.文中还通过算例对比分析了上述二维、拟三维弹塑性地震反应分析方法的计算结果.更多还原

【Abstract】 According to the cooperating model of the frame-shear wall structures,a two-dimensional elastic-plastic analysis model and the corresponding calculation method is determined to analyze the seismic response of the steel frame-concrete tube hybrid structures.Then,based on the above method,the spatial restrain effects of the transverse beam between steel frame and concrete tube are considered.For the spatial re- strain effects of the transverse beam between steel frame and concrete can be simulated by the vertical spring and reverse spring,considered both of them,a pseudo-three-dimension elastic-plastic seismic response a- nalysis method is also established.At last,the corresponding analysis program is complied on the basis of the large special computer program DRAIN-2D and added to DRAIN-2D as the program,then the pseudo- three-dimension elastic-plastic seismic response analysis method of the hybrid structures is given by using the determined analysis model.Furthermore,the results of the two-dimensional,three-dimensional elastic-plastic seismic response method are also compared and analyzed by some cases更多还原
