摘要

采用HBTA2.5程序,对一变刚度钢管混凝土短柱隔震结构进行了弹塑性时程分析。分析结果表明,其隔震装置的水平变形和耗能能力可以大大减轻地震对结构的影响。提出钢管混凝土短柱隔震结构在工程应用将有很好的发展前景。
Elasto-plastic dynamics analysis for the structure with variable stiffness base isolator made of CFST short columns is performed through the program HBTA2.5. The structure is assumed to be under bi-directional earthquake waves. According to the results, the seismic response of the structure is significantly reduced by the distortion and energy dissipation ability of the base-isolation system. Summarily, the variable stiffness base isolator with CFST short columns has good prospects in engineering practice.
