The number of high-rise buildings has greatly increased in Korea, and storey height is a significant component of tall residential buildings due to the limited city area. To reduce storey height, the wide beam has been adopted in some projects in Seoul such as Trump World, Galleria Palace, and Richencia. The joints between the wide beam and the core wall were too narrow to place the reinforcement, however. This paper investigates a newly developed structural system called the innovative, technical, economical, and convenient hybrid system (iTECH system). The iTECH system has an asymmetric steel assembly with web openings, where the top plate is welded on top of inverted structural "tees" whose cut is referred to as a "honeycomb" type. Both sides of the web and the slab are filled with cast-in-place concrete. The shear capacity was experimentally evaluated and verified, with parameters determined by factors that shared the shear strength of the iTECH beam. The steel web, inner concrete panel, and outer concrete panel contributed to the shear strength of the iTECH beam. The shear stirrup did not contribute much to the shear strength, however, and therefore a design equation using the steel web and inner concrete panel was suggested.Key words: composite beam, shear capacity, monotonic test, high-rise building.
