Based On Finite Element Analysis Of Seismic Test Of The Haunched Beam Transfer Floor Of Framed Short-leg Shear Wall Structures

In order to meet the special needs of building function, a small portion of shortlimb shear wall need been arrangemented in the middle of the beam. But the distributionof shear walls makes the beam more complex, and it bears more shear.In this paper, through the experiment, which is two shear wall limb structurespecimens under low cyclic loading, recording the location and process of specimencrack, measuring the lateral displacement and strain of steel bars,and getting in-depthanalysis. On the basis of analysis, this paper draw the conclusion which is failurepattern, stress mechanism, ductility, stiffness degradation and energy dissipationcapacity.what’s more, contrast the experiment results of the five specimens,obtaining thedifferent influence on the teansfer floor when the specimens with different width ofhaunch,different length of wall, different arrangement of short-leg shear wall.The experiment results show that increasing the length of wall has a certain impacton the longitudinal reinforcement of beam, as the joint action of beam and wall.Andthe strain of longitudinal reinforcementin is gentle.But the impact of this fact willbecome little when the wall is too long.Increasing the width of haunch lets thelongitudinal reinforcement force of beam more gentle.It helps delay the cracks of thebeam.Layout forms of wall limb also has great influence on the seismic performance.So one conclusion can be drawn, which is the wall limb layout form of the transferstructure hasn’t good ductility and deformation capacity, but also can have betterseismic performance after the reasonable design.
