Experimental Study on Reinforced Concrete ShortLeg Shear Walls with Dual Binding Beams

Abstract:

Pseudo static tests are conducted on the same four fourstory 1∶3 scaled shortleg shear wall specimens with dual binding beams in a bid to investigate how concrete stochastic characteristic affects the structural responses.Structure design,material preparation,specimen construction and loading system are fabricated strictly so as to eliminate other uncertain factors.Loaddisplacement curves,strain curves and partial relative displacement curves are obtained.Moreover,the bearing capacity,stiffness,and ductility are discussed.Strains variability,displacements variability and redistributed inner forces behavior of three typical crosssections are studied.Finally,failure characteristic of different specimens is contrasted.It is concluded that coupling of concrete randomicity and nonlinearity has notable effects on structural responses.

Key words:shortleg shear walls with dual binding beams (DW); redistribution; randomicity
