Experimental study on seismic performance of self-centering prefabricated RC frame beam-column joint with pre-pressed disc springs
摘要
Abstract
To assess the seismic performance of prefabricated RC frame beam-column joints with pre-pressed disc spring self-centering devices,a quasi-static test was performed on the joint.The joint adopts disc spring self-centering devices to provide restoring force,employs rotational friction damper to dissipate seismic energy,and is assembled through friction-type high-strength bolt connections.The main design parameters are the self-centering ratio α and the moment regulation coefficient β,with value ranges of 1.00-2.38 and 1.2-2.34,respectively.A total of four beam-column joints were fabricated to verify the feasibility of the joint configuration,investigate the hysteretic performance and energy dissipation mechanism of the joints under low-cycle reversed loading,and quantitatively evaluate their self-centering capability.Test results demonstrate that the force-displacement curves of the joints display flag-shaped hysteretic behavior.The installation of rotational friction dampers enables the beam-column joint to form a concentrated energy dissipation mechanism,thereby protecting the beam and column components from damage.The disc spring self-centering device effectively controls the residual deformation of the joint and enhance its recoverable function.The energy dissipation mechanism of rotational friction dampers originates from the adhesion effect and the plowing effect between the contact surfaces.With the self-centering ratio α controlled at 2.38 and the moment regulation coefficient β at 1.42,when the loading drift ratio of this type of beam-column joint reaches 0.03 rad,the controllable plastic hinge rotation can reach 0.028 rad,while the residual drift ratio can still be controlled within 0.002 rad.The beam and column components can remain in a damage-free or low-damage state.关键词
