Research on the Calculation Method of Vertical Seismic Capacity of the Multi-Ribbed Composite Slab

Qi Zhang, Qian Yao, Yin Zhang, Wei Huang, Dong Bo Li

Abstract

On the basis of experimental study on 5 standard slabs’ vertical bearing capacity, the paper makes an in-depth analysis on the ratio of axial compression stress to strength, the ratio of height to thickness and the influence of embedded block on the axial bearing capacity of the slabs. By establishing finite element model of the slab, the paper analysis the influence factors by means of numerical simulation and establishing the theoretical calculation formula of the slab. Compared with the experimental results, it is showed that the accuracy of the theoretical calculation formula can meet the practical requirements, which provides theoretical calculation basis for engineering practice.
