Abstract

In the case of H-shaped section bracing, the flexural buckling strength can be improved by increasing the cross section over the middle portion. For example, the increase in sections is accomplished by welding additional plates. The compression tests in inelastic ranges were conducted on the pin-ended columns reinforced H-shaped section by welding plates. The buckling behavior and the mode are examined for the members having a variety of proportion. It is found that the corresponding buckling strength can be larger than the column curve of the design standard for steel structures.
