Abstract
In this study, the experimental bending behaviors of an H-secti on-steel-beam-attached high-strength steel plate or steel beam were analyzed. Its structural performance was verified by comparing the results of the experiment and the analysis that were conducted. In fabricating an unprestressed composite beam using two members that have different strengths, the generated slip on the joint in proport problem because of the redistribution of force caused by the lose state of the joint. Therefore, when fabricating composite beams, it is important to load them with prestressed forces. Based on the results of the experiment that was conducted, the prestressed composite-steel-beam-attached steel plate or beam has a higher bending resistance and load-carrying capacit
