摘要
本文分析了新型钢棒-铅棒组合隔震的减震效果.选取了El-centro、Tar-tarzana和人工波等3条合适的地震波,采用时程分析方法,对8度地区多遇地震和罕遇地震情况下的传统抗震结构和新型钢棒-铅棒组合隔震结构的内力和位移时程变化进行了研究,对比了这两种结构的加速度、楼层剪力及层间位移反应,并对隔震构件钢棒、铅棒作用于隔震层的减震效果进行了分析.结果表明,与传统抗震结构相比,采用新型钢棒-铅棒组合隔震技术的隔震结构的减震效果显著,其减震率可达50%以上,与最为成熟的叠层橡胶隔震技术相比,其减震效果也非常显著,且新型钢棒-铅棒组合隔震技术更加经济,可在实际工程中推广使用.
The damping effect of the new steel bar-lead rod combined isolation was analyzed in this paper.selected the three suitable seismic waves El-centro,Tar-tarzana and the artificial wave,the internal force and displacement time history change of the traditional anti-seismic structure and the new steel bar-lead rod combined isolation structure were studied by the analysis method of time history under the cases of the frequent earthquake and the rare earthquake in the 8 degrees areas.The responses of the acceleration,the shear force and displacement between storeys between the above two structures were compared and the damping effect of the new steel bar-lead rod isolation component acted on the isolation layer was analyzed.The results show that compared with the traditional anti-seismic structure,the damping effect of the isolated structure used by the isolation technology of the new steel bar-lead rod combination is remarkable,its damping ratio reaches to 50% more than,and compared with the most mature laminated rubber isolation technology,the damping effect is also very significant,and the new steel bar-lead rod combined isolation technology is more economic and can be widely used in practical engineering.
