Numerical modeling of single closed and open-ended pipe pile embedded in dry soil layers under coupled static and dynamic loadings

Abstract For the design of a deep foundation, piles are presumed to transfer axial and lateral loads into ground. However, effects combined generally ignored in engineering practice since there uncertainties precise definition soil–pile interactions. Hence, for technical discussions interactions due dynamic loads, three-dimensional finite element model was developed evaluate soil pile performance based on 1 g shaking table test. The static consisted 50% allowable vertical capacity capacity. were taken from recorded data Kobe earthquake. current numerical takes account material non-linearity pile-to-surrounded contact surfaces. A ground acceleration adapted simulate seismic effects. This research emphasizes modeling by adapting MIDAS GTS NX software. will, turn, present main findings single under load. Consequently, results first validated then used further investigations. predicted slightly higher displacement horizontal directions than table. shear stress–shear strain relationship predicted. Positive frictional resistance closed-ended captured during 5 s when low values applied and, consequently, decreased became negative. Internal external open-ended pipe pile. Overall, with time until they reached last step minimum value. As result, evaluation study can be as guide analysis preliminary practice.
