摘要

某项目为重点设防类建筑物,属一般不规则结构,为减小地震反应,布置了金属阻尼器,以消耗地震能量,达到抗震设防目标。采用SAP2000对结构进行结构弹塑性时程分析,罕遇地震作用下,各个阻尼器基本进入塑性,耗能能力作用明显。在金属软钢阻尼器加设后,产生了很好的抗震作用,结构安全度得到了大幅提高。
        This project is the key fortification building, which belongs to the general irregular structure. In order to reduce the seismic response, the metal dampers are arranged to consume the seismic energy and reach the seismic fortification target. The elastoplastic time history analysis of the structure is carried out by SAP2000. Under the action of rare earthquakes, the dampers basically enter into plasticity, and the energy dissipation capability is obvious. After the addition of the metal soft steel damper, a good seismic action was achieved, and the structural safety was greatly improved.
