Type: article
Abstract: Using finite element software Abaqus, the ultra-high-performance concrete composite beam (UHPC-NC) was used as an example to simulate the working performance of two types of concrete when working together. By comparing UHPC-NC beams with UHPC beams, it was analyzed how to reasonably use NC and UHPC to fully utilize UHPC's ultra-high performance. By comparing UHPC beams with NC beams, the feasibility of replacing rebar in NC beam bodies was analyzed. Research results show that when the steel fiber volume content of UHPC beams is 2%, the bearing capacity can reach 72.7% of the NC beam with a reinforcement ratio of 1.5%. There is no significant difference in bearing capacity between UHPC beams and UHPC-NC composite beams, but UHPC-NC composite beams have greater economic value
