In order to obtain the best fabricated floor structure for construction projects, based on the non-linear finite element software ABAQUS, the PC floor and cast-in-place floor slabs of the C30 floor slab scheme of the Jiangyin Jinyi Project were fully simulated. Through the comparison of the two simulation results, it is found that the stress concentration at the center of the cast-in-place floor structure under the full static load is significantly greater than that of the PC floor structure; unlike the uniform force of the PC board, the most vulnerable position of the cast-in-place floor structure is The longer side is not the uniform force of the overall floor structure; after checking the ultimate bearing capacity, strength and deflection of the PC floor structure, it is found that the ultimate bearing capacity of the PC floor structure is 9.187 kN/m and the deflection is 0.049 mm, which are far less than The theoretical value of the design of the floor structure shows that it is feasible to select the PC floor structure in the assembly type of construction engineering, and it is recommended to popularize and apply it in engineering practice.
