| 摘 要： | 结合一幢多层框架结构应用铅芯叠层橡胶支座(LRB)进行加层改造的工程实例,在对隔震层的抗侧刚度和阻尼比基于能量准则进行优化的基础上,利用Matlab语言编制了能量时程分析程序,考虑地震动三要素和铅芯隔震支座动力特性(屈服位移和第二刚度系数)等影响因素,分析典型地震动作用下设置上述隔震元件LRB加层结构的能量输入、转化及耗散特性.分析结果表明,输入到结构的总能量较加层前有不同程度的增加,但是大部分都由隔震层来吸收和耗散,使得输入到原主体结构的能量较加层前大大降低,减震效果较为明显,证明提出的基于能量的优化准则的合理性与有效性. |
| 关 键 词： | 铅芯叠层隔震支座 框架结构 加层 减震 能量 |
