摘要:Laterally loaded pile is a famous case of soil-structure interaction problem which was intensivelystudied by many researchers before. The techniques used to predict the behavior of laterally loaded piles weredeveloped with increasing of the available computational capabilities from closed mathematical formulas to finitedifferences technique and finally linear finite elements technique. Recently, very sophisticated 3D elasto-plastic nonlinearfinite element models were used to accurately predict that behavior. Unfortunately, those sophisticated modelsare too complicated to be used in practical design. Hence, the aim of this research is to introduce a much simpler andpractical approach to predict the behavior of the laterally loaded concrete piles considering the nonlinear effect ofconcrete cracking. Special calculating tool based on finite elements is developed to carry out a parametric study of thebehavior of a set of 24 piles with different aspect ratios, reinforcement ratios, relative stiffness and head constrains. Thevalidity of the calculating tool is checked against case history field tests. The results of the parametric study show threedifferent failure modes according to the flexibility of the pile. Comparing the results with the formulas of ECP (202/4)shows the matching in the ultimate lateral capacity, while the ultimate lateral deformations are about (127 to 132%) ofthe code prediction.
