Experimental Study of Short Column with Welded H-Sharped Steel Reinforced Concrete under Axial Compresion

Abstract：In order to study Force Performance of new column, the paper describes and presents the results of nine stub-column tests performed on partially encased composite columns made with welded H-section steel. The test studies effect of column about ultimate strength in s steel ratio, wide-thickness ratio of wing, Space of Horizontal bar. Through anglicizing, ultimate strength of short column under axial compression in different steel ratio; influenced factors of ultimate strength of short column and directly effected column about ultimate strength.
