단부보강 철골보(Eco-girder)의 휨성능 평가

When column-beam connection is designed under distribution load, the beam height is decided bending moment which was occurred in both side. In this case, the beam height becomes large because beam is designed by both side moment which are 2 times than center moment. If both side of H shape beam are reinforced to certain length for solution, the economic beam design is possible by center moment In this study, we would like to analysis stiffness change theoretical through changing of section area
