Abstract
Response of individual piles to externally applied loads is one of the most complex soil-structure interaction problems in the field of foundation engineering. For any realistic analysis of this problem, it is essential to 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 and results are presented for the problem of axially and laterally loaded piles, taking into account elasto-plastic nature of the soil for both cohesive and cohesionless soils. The results indicate that the flexural behaviour of laterally and axially 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.
