摘要
结合西安某框架结构小学项目设计,该工程采用剪切型金属阻尼器作为耗能部件;利用PKPM-JZ模块对该项目进行计算分析,采用规范规定的能量法对减震结构附加阻尼比进行计算,同时对普通抗震结构与减震结构的经济性指标进行对比;结果表明采用该方案的消能减震结构从成本上较普通抗震结构有所提升,但在高烈度地区消能减震结构可更好地满足建筑使用功能的需求,同时也能达到预设的结构抗震性能目标。
Combined with the design of a frame structure primary school project in Xi’an,which uses shear metal dampers as energy dissipation part;The PKPM-JZ module is used to calculate and analyze the project,and the additional damping ratio of the damping structure is calculated by the energy method specified in the code.Meanwhile,the economic index of the ordinary seismic structure and the damping structure are compared.The results show that the energy dissipation structure adopted in this scheme has a higher cost than the ordinary seismic structure,but the energy dissipation structure can better meet the requirements of building function in high seismic fortification intensity area,and at the same time,it can also achieve the preset seismic performance objectives of structure.
