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.

Comprehensive Study

The test results of nine stub-column tests performed on partially encased composite (PEC) columns made with welded H-section steel are described and presented. The H-section steel is stiffened with transverse link and concrete is poured between the flanges of the steel section. The axial comprehensive study has been conducted on all specimens to investigate the ultimate axial capacity of PEC columns. The failure of all columns is due to local buckling of the flanges along with concrete crushing. Closer link spacing improves the ductility of the columns; however, the measurements show that in general yielding do not occur before the peak load in the links. The additional longitudinal bars have no a remarkable effect to the strength of the composite columns. Finally, an equation is proposed to predict the ultimate axial capacity of the partially encased composite column.
