Ultra-high-performance concrete (UHPC) exhibits significantly higher tensile strength compared to normal (NC). In this paper, the application of UHPC precast base plate composite slabs was proposed, leading development a reinforced truss UHPC-NC slab. This approach effectively enhanced crack resistance A finite element model (FEM) for slab developed based on ABAQUS (2016) platform, using appropriate material constitutive relationships UHPC, NC, and steel reinforcement. The validity verified through comparison with relevant test results. Subsequently, effects parameters such as cross-sectional area upper lower chords, reinforcement ratio plate, grade thickness flexural capacity were investigated. Finally, equations calculating proposed. It found that increasing chord improved stiffness some extent, though ductility slightly reduced. On other hand, had limited impact performance. Increasing longitudinal in load-bearing but similarly reduced ductility. As increased, cracking load, yield ultimate load also increased. However, when exceeded C120, improvement became less significant. With an increase cracking, yield, loads rose, decreased. When 60 mm, modest. proposed section agreed well simulation results, providing theoretical numerical support design analysis slabs.
