【Abstract】 A new lead shear energy dissipation device,which was installed in the plastic hinge of a beam-end,was proposed,and it was primarily used in the dissipation of earthquake energy.The analytical results expatiated that this type of device could effectively increase the damping ratio of concrete structure,with outstanding energy dissipation decreased.A numberical model was presented for the calculation of a frame structure during an earthquake,and the results indicated that the composite lead energy dissipation device was effective.更多还原
