EXPERIMENTAL STUDY ON THE SHEAR CARRYING CAPACITY OF Z-SHAPED COLUMN

The shear carrying capacity experiment of Z-shaped column was carried out,through the synthetic analysis of both crack expanding condition and failure modes,the shear failure mechanism and shear failure law were studied,it was obfained the effect of the factors,such as axial compression ratio,shear span ratio,stirrup reinforcement ratio and ratio of section height to section thickness of column 1eg,which affected the shear carrying capacity and ductility capacity of Z-shaped column.And based on the results of the experiment,the regression formula,the formula for the structure design and some suggestions on design of practical projects were presented,which provided a reference for structure designer.
