A modified strain wedge model for analyzing the lateral response of reinforced concrete piles in sand is proposed in this paper. To address the limitations of the strain wedge model, the relationship between the lateral displacement of the pile and the soil strain is modified. This modification comprehensively considers the effects of the global compression of the soil and the local angle of the pile on the soil strain. The validity and accuracy of the proposed model are verified by published centrifuge test results and field test results. Finally, the effects of pile materials, pile geometry, and pile head boundary conditions on the lateral response of reinforced concrete piles in sand are discussed. • A modified SW model is proposed to analyze the plasticity development of RC piles subjected to lateral load in sand. • The model modifies the relationship between pile displacement and soil strain using layer-by-layer area equivalence. • The effects of material, geometry and boundary of piles on the plastic behavior of RC piles are discussed using this model.
