SHEAR FORCE AND HORIZONTAL RELATIVE DISPLACEMENT RELATIONSHIP OF L-SHAPE SHEAR CONNECTOR SUBJECTED TO STRUT COMPRESSIVE FORCE IN STEEL-CONCRETE COMPOSITE STRUCTURE

Abstract

  This study examines the relationship between shear force and horizontal relative displacement of L-shape shear connector by means of beam type test method. An equation for maximum shear force of the specimen which takes into account the effects of size of the shear connector and the concrete strength was proposed. It was found that shear force-horizontal relative displacement relationship can be represented by a unique enveloped curve by normalizing shear force by maximum shear force and horizontal relative displacement by the height of the shear connector. The predicted maximum shear forces and shear force-horizontal relative displacement relationships were found to agree with the experimental results.
