Experimental study on seismic behavior of monolithic precast reinforced concrete shear wall substructure
摘要
Abstract
To examine the seismic performance of the proposed monolithic precast RC shear wall structures,a fullscale three-story substructure was tested under reversal cyclic loads.The test specimen contains four types of connections,namely,the ‘ dry connections’ and the ‘ cast-in-situ elbow RC joints’ to connect precast RC walls at the same story,and the ‘ shaped steel shear keys’ and the ‘ shaped steel boundary elements’ to connect the walls at different stories.The test results demonstrate that the specimen performs well in terms of the seismic resistance.The coupling beams play the role of the first defense against the lateral force.When the test was finished,apparent shear failure damages were observed in most coupling beams.These coupling beams had a considerable energy-dissipating capacity.The ‘dry connections’ yielded gradually,which are deemed as the second seismic defense measure.With the increase of lateral deformation,some ‘dry connections’ fractured at the welding joints,and wall pieces lost confinement in the section plane and punched significantly to the slabs.The steel members and the vertical reinforcements in the post-cast corner walls yielded subsequently at the drift ratio of 1/150 and 1/100,respectively.When the drift ratio reached 1/75,the specimen still has enough bearing capacity and the integrity of assembled members remained.It is concluded that this monolithic precast RC shear wall structure has a similar seismic performance to the one completely cast-in-situ.关键词
