GENERALIZED SOLUTIONS FOR LATERALLY LOADED PILE IN ELASTO-PLASTIC SOIL

Abstract

Response of vertical pile to the action of lateral loads is one of the complex soil-structure interaction problems in the field of foundation engineering. Any realistic analysis of the problem should take into account both the elastic and plastic properties of the soil, as both these states occur along the embedded length of the pile. Herein, analysis of laterally loaded piles is presented taking elasto-plastic nature of the soil into account for both cohesive and cohesionless soils. The results show that the flexural behaviour of laterally loaded pile in an elasto-plastic soil is considerably influenced by type of variation of plastic resistance, soil modulus variation and the boundary conditions at the top.
