Experimental study on seismic behavior of reinforced concrete composite shear wall with level splice

Abstract

Quasi-static tests on three reinforced concrete composite shear walls with level splice and one reinforced concrete composite shear wall without level splice under cyclic loading were reported.Quasi-static test on one reinforced concrete shear wall under cyclic loading was reported too.The deformation properties and failure mode were discussed.The bearing capacity,hysteretic loops,skeleton curves,ductility and energy-dissipation were analyzed.Test results indicate that the mechanical behavior of the reinforced concrete composite shear walls with level splice and the reinforced concrete composite shear wall without level splice is the same as that of the reinforced concrete shear wall.The study shows that the reinforced concrete composite shear walls with level splice have good seismic behavior.The detailing requirements of the level splice are reasonable,and the load-carrying capacity of the reinforced concrete composite shear walls with level splice is greater than that of the reinforced concrete composite shear wall without level splice.The prefabricated parts and the cast-in-situ concrete parts of the reinforced concrete composite shear walls can work together very well under loading.
