RESEARCH ON SHEAR CRACK LOADING OF STEEL REINFORCED CONCRETE SPECIAL-SHAPED COLUMNS

摘要：

according to the experimental research on 12 small shear span ratio specimens of steel reinforced concrete (SRC) special-shaped columns under low cyclic reversed loading; the shear crack loading of the specimens can be obtained. The influence of shear span ratio, axial compression ratio and loading direction on shear crack loading are analyzed. And through compiling computer program, the influence of the flange of SRC special-shaped columns on the shear crack loading are researched,and the flange enhance coefficient to the shear crack loading is given. According to the analysis result and considering the influence of shape steel, the formula of shear crack loading is established. The formulas calculation results are satisfactory well with the experimental results. All this may be helpful to the designation of SRC special-shaped columns.
