【摘要】 以砖混结构作为研究对象,探讨了采用基底滑移隔震技术后的减震效果及其地震反应的特点。为此,运用FORTRAN编制的结构隔震动力时程分析程序,对其进行计算。以2～8层砖混结构建筑为算例,分别考虑了不隔震(传统抗震)、基底滑移隔震两种方案,对其输入El-Centro波,并且选取不同的摩擦系数,进行了大量的比较计算分析,得出了一些有益的结论。更多还原

【Abstract】 The seismic reduction effectiveness and earthquake response of BC structures adopting base-isolation is studied.A FORTRAN program to dynamic time history was used to analyze the character of the nonlinear structure.The BC structure from 2 to 8 storey adopting two techniques respectively:traditional technique(foundation-fix),base-isolation,was analyzed as an example.The El-Centro earthquake wave was imposed on the structure as an excitation with different friction coefficient.Some useful results are obtained through lots of comparative analysis.更多还原
