【摘要】 结合一个实际工程,分析了该结构在隔震加固前后及是否考虑土-结构动力相互作用共4种情况,得出了各种情况下结构的周期、层间剪力、楼层位移、隔震支座性能、地震能量输入与结构能量反应的变化等,并得出了一些结论。更多还原

【Abstract】 In this paper we study four condition with a structure which is wrecked in the wenchuan-earthquake.①unconsidering soil-structure dynamic interaction before strengthening.②considering soil-structure dynamic interaction before strengthening.③unconsidering soil-structure dynamic interaction after base isolated strengthening.④considering soil-structure dynamic interaction after base isolated strengthening.We get some results about period,story shear,story displacement,story acceleration,shear of vibration cushion,displacement of vibration cushion and hysteretic characteristics of vibration cushion.更多还原
