摘　　要：根据《建设工程抗震管理条例》规定,重点监视防御区乙类建筑应进行减震设计。以7度(0.1 g)地区一栋学生宿舍为例,通过合理的选择与布置阻尼器增加结构的附加阻尼,消耗由地震所产生的地震能量,减轻地震对结构的作用。计算结果表明:设置速度型阻尼器后,该结构在多遇地震下楼层层间剪力与层间位移角明显减小,在设防地震作用下阻尼器可正常工作,在罕遇地震作用下阻尼器变形性能良好,起到很好的耗能作用,达到结构抗震性能目标。According to the regulations on seismic management of construction projects,the seismic reduction design should be carried out for Class B buildings in key surveillance and defense areas.Taking a student dormitory in a 7-degree(0.1 g)area as an example,the additional damping of the structure is increased through reasonable selection and arrangement of dampers,which consumes the seismic energy generated by the earthquake and reduces the effect of the earthquake on the structure.The calculation results show that the shear force and drift angle between floors of the structure are obviously reduced after setting the velocity damper,and the damper can work normally under the action of fortification earthquake,and the dampers have good deformation performance under the action of rare earthquake,which plays a good role in energy dissipation,and achieves the goal of structural seismic performance.
