Web openings can be used to pass utilities through beams and to minimize story height. Decreasing building height reduces both the exterior surface and the interior volume of a building, which lowers operational and maintenance cost, as well as construction cost. Recently, using composite structures and PEBS(Pre-Engineered Building System) has steadily increased. Sometimes it requires non-compact section for web to reduce steel usage. According AISC Design Guide, the web opening should be only provided in the compact section. In this study, the changes in buckling load, yielding strength, and the deformation of specimens were evaluated experimentally for the non-compact section steel beam.
