【Abstract】 A earthquake resistant design method of steel tall buildings installed with viscoelastic dampers(VED) is studied. The elemental complex stiffness matrix of VED brace is established firstly. The effective damping ratio of steel tall buildings installed with VED is solved. Then, the parametrical design of VED is carried out. A 12-storey building is adopted to confirm the efficiency of the earthquake resistant of steel tall buildings installed with VED.更多还原
