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.
