TEST ON SEISMIC BEHAVIOR OF I-SHAPED SECTION SUPERIMPOSED SEMI-PRECAST REINFORCED CONCRETE WALLS
To evaluate seismic behavior of the superimposed semi-precast RC wall structures,two full-scale (I)-shaped cross section specimens consisting of the perpendicular walls and the T-shaped edge elements were tested under cyclic reversed loads.The test results indicate that inelastic deformation of the semi-precast RC wall concentrated near the horizontal connections of the wall and foundation,while damage of the wall panel is relative minor; the test specimens have enough strength and stiffness; with opening of the horizontal gap between the wall and foundation,part of the longitudinal reinforcing bars ruptured,resulting in decreasing of the ductility,however,the specimens have enough deformation ability,and the maximal drift requirement of Chinese seismic design code could be fulfilled; since no axial load was conducted to the specimens,obvious shear slip between the wall and foundation was observed during the test; the specimens have steady hysteresis behavior,and the hysteresis loops present obvious pinching character due to the horizontal shear slip; the cast in place T-shaped edge member could work well with the superimposed walls,while concrete in the edge member was damaged severely,since the concrete strength is lower.
