ABSTRACT
Hybrid beam with continuous web is a flexible com posite section. Load bearing characteristics significantly depend on the stiffness of the connection between flanges and web. This is presented in the Figure 1. First lim it case is the beam 1 which presents a rigidly connected section. There is no displacem ent between steel and glass. Steel flanges are loaded with moments and high normal forces. This leads to a high load carry ing capacity. Second limit case is beam 3 which consist of unconnected section members. There is a high displacement between steel and glass. All section members are loaded with bending moments only. Because of the low bending stiffness and resistance of flanges, beam 3 has low carry ing capacity and high deflections compared to beam 1. The behaviour of bonded hy brid steel-glass-beam is located in between these two cases as a beam 2. There is a displacement between steel and glass and partial loss of interaction due to adhesive flexibility.
