Numerical assessment of soil structure interaction problems require heavy computational efforts because of the dynamic and iterative (nonlinear) nature of the problems. Furthermore, modeling soil-structure interaction may require ﬁner meshes in order to get reliable results. Latest computing technologies must be utilized to achieve results in reasonable run times. This study focuses on development and implantation of a parallel dynamic ﬁnite element analysis method for numerical solution of soil-structure interaction problems. For this purpose ﬁrst, an extensible parallel ﬁnite element analysis library was developed. Then this library was extended with algorithms that implement the parallel dynamic solution method. Parallel dynamic solution algorithm is based on Implicit Newmark integration algorithm. This algorithm was parallelized using MPI (Message Passing Interface). For numerical modeling of soil material an equivalent linear material model was used. Additional numerical veriﬁcation of the implemented equivalent linear material model was shown by comparisons with EduShake software. Several tests were done to benchmark and demonstrate parallel performance of implemented algorithms.
