The pile foundation is adopted to transfer the load from the structure to the soil when the structure is embedded in a weak soil stratum. Soil-pile system has a nonlinear behavior, thus, it is more complicated to understand. This study focuses on the numerical investigations of interaction soilâ��pileâ��structure system (ISPS) and interaction soilâ��pile system (ISP) under lateral loads. The nonlinear static analysis is carried out considering the lateral capacity of ISPS and ISP system under lateral loading using the pushover analysis, with a parametric study. The results show that in most cases, the lateral capacity of the fixed system is low compared to lateral capacity in ISPS system when increasing the axial load, pile diameter and length of the pile in all types of sand. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2021. %J Lecture Notes in Civil Engineering %L scholars15894 %O cited By 0; Conference of 6th International Conference on Civil, Offshore and Environmental Engineering, ICCOEE 2020 ; Conference Date: 13 July 2021 Through 15 July 2021; Conference Code:253689 %R 10.1007/978-981-33-6311-3₁₁₅ %D 2021 %A K.
