Abstract
The purpose of this study was to evaluate structural safety and economic efficiency of prestressed hybrid beam using T-shape steel member which was developed to build large span educational facilities. Hybrid beam specimens were manufactured with 16.0m long and load was uniformly distributed by 12.0kN steel hexahedrons. In this study, honeycomb beam design process was introduced to T-shape section steel beam design. Vibration condition of specimens were analyzed by Korea Building Code 2009 and AISC Steel Design Guide Series-11. As a result, the prestressed hybrid beam with T-shape steel member has about 10.4% of cost reduction effect.
