| Abstract: | The element stiffness matrix and element damping matrix of velocity|depended da mper in member|story model are presented. On the basis of program HBTA,an updat ed version of HBTA is programmed which can make nonlinear analysis for seismic m itigation structure with velocity|depended dampers. The seismic response of a s teel frame model is analyzed by HBTA,and the results are compared with those fr om SAP2000. Time|history analysis for a reinforced concrete structure under int ensive earthquake excitation is performed, and different effects of different a nalytical models for viscoelastic damper are compared. |
