Abstract

Abstract

In order to study the influence of key parameters such as steel strength, concrete strength, steel flange thickness, steel web thickness, column height, stud spacing, and stirrup spacing on the bearing capacity and failure mode of L-shaped steel special-shaped columns, a total of 5 sets of comparative members were designed for the finite element analysis under axial compression. The failure mode, load-displacement curve, stress distribution of profiled steel and concrete, etc. were obtained to analyze the performance of the special-shaped column under axial compression. The results showed that the structure of the special-shaped column with L-shaped steel was reasonable. With the increase of steel strength, steel ratio and concrete strength, the bearing capacity gradually increased. When the column height changed from 3 meters to 5 meters, it had little effect on the ultimate bearing capacity of special-shaped columns. The effects of stud spacing and stirrup spacing on the bearing capacity could be ignored.
