Combined Application of Hybrid Damping Design in Prefabricated Frame Structures
With the increasing development of building industrialization and the promulgation of the regulations on Seismic Management of Construction Engineering,the earthquake prevention and disaster reduction capability of prefabricated and modular building structures has gradually become a research hotspot.The prefabricated frame structure has the characteristics of small lateral stiffness,lightweight,and large lattice deformation,so it is more suitable for the internal damping equipment to realize the response control under the earthquake,to improve the seismic performance of the prefabricated frame structure.Before the displacement damper reaches the yield point,it can provide stable lateral stiffness and bearing capacity to meet the operational requirements.After yield,the damper first enters the state of yield energy dissipation and provides an additional damping ratio for the structure.The velocity damper can work as long as the structure produces relative displacement,providing an additional damping ratio for the structure.It is worth noting that a single and too-high additional damping ratio has no more practical significance,especially in the structural seismic fortification requirements for multi-level and multi-stage structures.This paper integrates these two kinds of energy dissipation devices for hybrid damping to achieve complementary advantages,which has important reference significance for the seismic design of structures requiring prefabricated frame structures to maintain normal use function.
