Substructure Pseudo-Dynamic Test Study for a Structure Including Soil–Pile–Structure Dynamic Interaction

An improved Penzien model is proposed in this paper as a simplified of soil–pile–structure interaction. The dynamic nonlinearity soil under earthquake excitation simulated by ANSYS free-field and added to the original model. uses finite element software 2021 simulate soil. then used calculation numerical substructure. A substructure pseudo-dynamic test based on carried out. realization verifies feasibility effectiveness method, which provides convenient method for study interaction general laboratories. Soil structure reduces acceleration structure, response exhibited hysteresis phenomenon because nonlinear characteristics influences velocity displacement are very complex. conclusions reasonable, proves that using feasible.
