摘要：

In order to analyze aseismic behaviors of a concrete lintel-column joint with a viscous damper in archaized buildings under seismic actions, 3 specimens were made including two ones with viscous dampers called controlled structures and one without viscous damper called non-controlled structure. The dynamic tests were conducted for these 3 joints. Their failure process and patterns were observed. Their failure characteristics, load-displacement hysteretic curves, skeleton curves, load-bearing capacity and stiffness degradation were analyzed. The test results indicated that the load-bearing capacity of two controlled structures is obviously higher than that of the non-controlled structure, the mean values of their yield load increase value and ultimate load increase value are 27.4% and 22.4%, respectively; meanwhile, the displacement ductility and the energy-dissipating ability of two controlled structures are superior to those of the non-controlled one. Compared with the non-controlled structure, the equivalent viscous damping coefficient of two controlled structures is improved by 27.3%~30.8%; so, the aseismic performance of the controlled structures is superior to that of the non-controlled one. © 2017, Editorial Office of Journal of Vibration and Shock.
