Application of pile-raft foundations, which are known as “compound foundations”, is a suitable alternative in the case of heavy load structures. The interaction behavior of pile raft foundations makes these systems very complex to analyze. Different methods have been proposed to determine the bearing capacity of piled raft systems and distribution of loads between the components, i.e. pile grou...

Recent investigations have shown that the influences of Soil-Structure Interaction (SSI) may be detrimental to the seismic response of structure, and hence neglecting this phenomenon in analysis and design may lead to an un-conservative design. The objective of this paper is to quantify the effects of nonlinear soil-structure interaction on the seismic response of a low-rise special moment fram...

A multiscale approach [1] that couples the finite-element method (FEM) and discrete-element (DEM) is employed to model analyse earthquake fault rupture-soil-foundation interaction (FR-SFI) problem. In approach, soil constitutive responses are obtained from DEM solutions of representative volume elements (RVEs) embedded at FEM integration points so as effectively bypass phenomenological hypothes...

The simultaneous effects of soil and existing structures are known as the site-city interaction (structure-soil-structure). The impact of site-city interaction on structure behavior is effective. Thus, this interaction in some regions decreases the responses while increases in other areas. In addition, the site-city interaction of many parameters including the soil type, density rate, height of...

in order to mobilize shallow soil to participate in the interaction of piled raft foundation sufficiently, the concept of piled raft has been modified to new type of foundation named composite piled raft. in the system of composite piled raft, the short piles made of flexible materials is used to strengthen the shallow soft soil, while the long piles made of relatively rigid materials is used t...

In this study, the monotonic and cyclic behavior of an offshore wind turbine with a monopile foundation installed in sand layer were evaluated centrifuge. A simplified was modeled, lateral load applied to tower under displacement control. The loading test ultimate capacity bending moment profiles different levels. During loading, variations moment-rotation responses, stiffness, moments along pi...
