Effect of Opening on Behavior of Raft Foundations Resting On Different Types of Sand Soil

Abstract

In this paper, the elasto-plastic finite element analysis is carried out using the three-dimensional PLAXIS program to study the effect of opening position and type of soil on behavior ofraft foundations under columns loads. The analysis has been done for raft foundations with middle, edge, and corner opening positions and the results are obtained for three different types of soil which are loose sand, medium dense sand and dense sand soil. The effect of opening positions and type of soilon behavior of raft foundations is presented in graphical form and it is discussed.
