| 摘 要： | 对不同场地条件下、不同周期的摩擦摆基础隔震结构在水平双向和单向地震作用下的隔震支座位移进行了对比分析,表明水平双向地震作用下隔震支座的总位移均明显大于水平单向地震作用下的支座位移。因而,在简化设计中确定摩擦摆基础隔震结构隔震支座位移时,可将水平单向地震作用下的隔震支座位移增大30%,以考虑水平双向地震作用对摩擦摆基础隔震结构隔震支座位移的影响。 |
| 关 键 词： | 基础隔震结构 摩擦摆 支座位移 水平双向地震作用 |

| Abstract: | The analysis on the isolator displacement of the structure isolated by friction pendulum system with different site and period under bilateral and unilateral earthquake excitation is carried out.The maximum isolator displacement under bilateral ground motions is obviously lager than that under unilateral ground motion.In order to considering the influence of bilateral earthquake excitations on the isolator displacement,the maximum isolator displacement can be determined by increasing 30 percent of the isola... |
