In seismic performance based design context, engineers are faced to a difficult task estimate the response of soil-structure interaction (SSI) systems. To accomplish this successfully, all sources random and epistemic uncertainties should be taken into account. However, uncertain parameters have not same influence on model response; sensitivity analysis is therefore required. This article treat...

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...

Integral Abutment Bridges (IAB) are defined as simple or multiple span bridges in which the bridge deck is cast monolithically with the abutment walls. This kind of bridges are becoming very popular due to different aspects such as good response under seismic loading, low initial costs, elimination of bearings, and less maintenance. However the main issue related to the analysis of this type of...
