[提要]通过对两个缩尺比为1∶25的多层钢筋混凝土框架剪力墙结构隔震与非隔震模型的模拟地震振动台对比试验,研究了隔震与非隔震结构在地震作用下的自振特性、阻尼比、地震反应特征、破坏形态和破坏机理。试验研究结果表明,与非隔震结构相比,隔震结构具有明显的减震效果。

Abstract:Based on the shaking table test of 1∶25 scale model of the isolated and nonisolated building constructed of reinforced concrete frames and shear walls, the dynamic properties, damping ratios, seismic responses, damage feature and cracking pattern of models are recorded and analyzed. Test results show that isolated structure has obvious efficiency comparing with nonisolated structure. The viewpoints can be referred in design of isolated building and in code compilation.
