Abstract

Abstract

In combination with the actual project, the design schemes of large-scale prefabricated concrete composite beams were compared and analyzed by using hollow partially precast steel reinforced concrete beams (HPSRC beams). Based on the experimental research, the method of rational selection of the cross section and calculation method for HPSRC beam was proposed. The calculation results showed that the HPSRC beam could effectively reduce the height of the prestressed reinforced concrete beam, reduce the structural weight and simplify the on-site construction process. Furthermore, the finite element analysis model was selected to simulate the two-stage construction process of HPSRC beam,and the stress and deflection of the two-stage construction can both meet the requirement of current standards.
