OPTIMAL SHAKEDOWN ANALYSIS OF LATERALLY LOADED PILE WITH LIMITED RESIDUAL STRAIN ENERGY

Reliability Based Optimal Design of Laterally Loaded Pile with Limited Residual Strain Energy Capacity

Abstract—In this study, a general approach to the reliability based limit analysis of laterally loaded piles is presented. In engineering practice the uncertainties play a very important role. The aim of this study is to evaluate the lateral load capacity of free-head and fixed-head long pile when plastic limit analysis is considered. In addition to the plastic limit analysis to control the pla...

Analysis Method for Laterally Loaded Pile Groups Using an Advanced Modeling of Reinforced Concrete Sections

A Boundary Element Method (BEM) approach was developed for the analysis of pile groups. The proposed method includes: the non-linear behavior of the soil by a hyperbolic modulus reduction curve; the non-linear response of reinforced concrete pile sections, also taking into account the influence of tension stiffening; the influence of suction by increasing the stiffness of shallow portions of so...

Laterally Loaded Single Pile Response Considering the Influence of Suction and Non-Linear Behaviour of Reinforced Concrete Sections

A hybrid BEM-p-y curves approach was developed for the single pile analysis with free/fixed head restraint conditions. The method considers the soil non-linear behaviour by means of p-y curves in series to a multi-layered elastic half-space. The non-linearity of reinforced concrete pile sections, also considering the influence of tension-stiffening, has been considered. The model reproduces the...

Laterally loaded rigid piles in cohesionless soil

In this paper, limiting force profile for laterally loaded rigid piles in sand and is differentiated from the on-pile force profile, from which elastic-plastic solutions are established and presented in explicity expressioins. Nonlinear responses of the piles are characterized by slip depths mobilized from mudline and the pile-tip. At the states of tip-yield and rotation point yield, expression...

Dynamic shakedown and degradation of elastic reactions in laterally impacted steel tubes

This paper reports some interesting observations on the response of laterally impacted steel tubes which in some respects have been considered to undergo an elastic shakedown. In an experimental study on the behaviour of axially compressed tubes under lateral impacts, it has been noticed that, after full development of plastic deformations in the impacted bodies, the structural system ceases to...
