【摘要】 利用结构动力分析和非线性有限元理论,采用杆系模型和折算弹性模量,研制了非线性时程分析程序,对钢骨高强混凝土框架结构进行动力分析,研究了不同地震波作用下的钢骨高强混凝土框架结构顶层位移反应,说明钢骨高强混凝土框架结构的底层仍然是薄弱层.更多还原

【Abstract】 Based on the essential assumption of planar linkage model,nonlinear seismic responses of steel encased highstrength concrete frame structure are analyzed.A calculating program has been established by use of mechanical model and applying temporal analytical method.Converted elastic modulus is used in the program in order to analyze plastoelastic seismic responses of steel encased high concrete frame structure.更多还原
