Abstract

To control the inter-storey displacement,this paper does systematic researches on response characteristics of storey-adding structure spanning existing building with steel frame under minor and major earthquake by using direct step-by-step integration method and investigates anti-seismic effect of storey-adding structures by means of friction energy-dissipation devices.The results indicate that the friction energy-dissipation devices effectively control displacement response and acceleration response,and the shear forces in frame column are significantly decreased,which makes optimal structural design possible.
