| Summary: | This paper presents a new research perspective for studying the influence of the web opening location on continuous composite beams. Nonlinear finite element models were established to precisely simulate continuous composite beams. The hole location was taken as the variable parameter, and the optimal web opening location of continuous composite beams was comprehensively analyzed and studied from five perspectives. The results show that the most advantageous location is the sagging bending moment region near the side supports. At this location, the composite beam has a relatively higher ultimate bearing capacity and ductility, and the beam is allowed to develop a certain degree of plasticity before shear failure of the opening. In addition, the web opening brings amplitude modulations at two moments to the continuous composite beam. |
