Abstract:

In order to study the force resistance properties of cast-in-situ hollow concrete floor structure, the current FEM software, ANSYS, was adopted to analyze the difference of force resistance between this floor structure and solid slab. Some stress distribution traits of this floor structure were made, and the differences of stress and displacement distribution figures between these slabs were compared so that some laws of internal force distribution of the hollow floor system were summarized. Based on these results, the characteristic of punching shear resistance was further analyzed. The results show that the crack pattern is taken into consideration; it can be realized that the force of the punching shear resistance must be related closely to the number of hollows crossing the punching cracks. These analyzed conclusions provide theoretical reference for the improvement of design method of this floor structure.
