BEHAVIOR OF PARTIALLY ENCASED COMPOSITE COLUMNS MADE WITH WELDED H-SECTION STEEL

The paper describes and presents the results of nine stub-column tests performed on partially encased composite (PEC) columns made with welded H-section steel. 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 behavior of PEC columns. The failure of all columns was 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 did not occur before the peak load in the links. The additional longitudinal bars had no a remarkable effect to the strength of the composite columns. Finally, an equation was proposed to predict the ultimate axial capacity of the partially encased composite column.
