EXPERIMENTAL STUDY ON BEHAVIOR OF COMPOSITE BEAM IN LARGE DEFORMATION RANGE UNDER HORIZONTAL UNIDIRECTIONAL LOAD

Loading tests have been conducted on subassemblage with wide composite beams to investigate the bearing capacity degradation of composite beams due to slab damage in the large deformation range. The experimental results show that the slab transfers stress over a wide range and that the axial force acting on the beam affects the occurrence of local buckling. Furthermore, an analytical model is proposed that takes into account its bearing capacity degradation characteristics.
