Recently hybrid beam system is widely used because it has many structural advantages such as short construction period and low story height etc. Generally steel wide flange beam exposure type and embedded type hybrid beams are constructed. Even though exposure hybrid beam is easily constructed, the fire proofing protection process is necessary because steel wide flange beam cannot resist to fire itself. Story height reduction type hybrid beam, which is introduced hybrid beam in this paper, does not need fire proofing protection process because it is constructed as a fully embedded type hybrid beam. Developed construction process and actual construction cases of story height reduction type hybrid beam were introduced in this study.
