Research on Reinforcing Methods of Continuous Steel-Concrete Composite Beams with Web Openings

Abstract:

By considering the four secondary moment functions ,which are developed according to virtual plastic stress distribution at the perforated section of continuous composite beam. reinforced opening proved to be necessary and reliable .Several reinforcing methods are reserched. mechanical properties are compared with FE results in different reinforced continuous composite beam.The result indicates that the bending and vertical shear capacity of continuous composite beam with web opening can be effectively enhanced to a certain extent. In addition,stiffness and local stability at web opening area are also increase. Effective reinforcing method is presented and can be used in engineering practice.
