Abstract

In order to study the flexural properties of steel plate-ultra-high performance concrete (UHPC) composite beams, the static test of the flexural properties of a steel sheet-UHPC composite beam was first carried out. Then, Abaqus finite element software was used to simulate the whole process of static loading of the specimen, and different ways were used to simulate the studs in the composite beam. The most appropriate model was thus selected. Finally, based on the calibrated finite element model, the parameters of the steel plate-UHPC composite beam were analyzed, the main parameters included: UHPC compressive strength, steel plate strength, and stud spacing and layout. The results show that in the finite element simulation analysis, the surface-surface contact finite element model is used, and the simulation analysis results are in good agreement with the measured values, which can better reflect the change law of deflection, strain, and slip in the steel plate-UHPC composite beam and be used as a reference for the subsequent finite element simulation analysis of steel plate-UHPC composite beams. The influence of each parameter on the ultimate bearing capacity of steel plate-UHPC composite beam in descending order is as follows: steel plate strength >UHPC compressive strength > stud spacing. In the structural design, it is necessary to pay attention to the selection and arrangement of studs in the shear section, while the studs in the pure section can be relatively weakened.
