Abstract:
Three-dimensional (3-D) elastic finite element (FE) analysis of isolated edge connections in multistory flat plate structures subjected to lateral loads is conducted. The floor slabs and columns are simulated using 20-noded solid isoparametric elements. The parameters studied are the slab aspect ratio and the square column dimension, within practical ranges. The salient advantages of using 3-D analysis are discussed. The transfer mechanism of unbalanced moments from the columns to the slabs is investigated using 3-D stress distributions at the column-slab interfaces, and at the so-called slab critical section. The contributions of various slab stress components to moment-resisting mechanism are compared with the results of another elastic model as well as with the predictions of the ACI eccentric shear model at ultimate.
