Soil-structure interaction analysis is one of the most challenging problems in field structural engineering. In this paper, two aspects less discussed literature, namely: (ⅰ) effect considering all three components near-field earthquake excitations instead just horizontal component, and (ⅱ) elimination part inter-story drifts caused by foundation rocking, have been investigated. Theoretical bot...

In this study, through series of shaking table tests and statistical analysis, the efficiency of Uniform Tuned Liquid Column Damper (UTLCD) in structures resting on loose soils, considering soil-structure interaction was investigated. The soil beneath the structure is loose sandy soil. The Laminar Shear Box (LSB) as a soil container was adopted and the scaled form of the prototype structure nam...

This study evaluates the movement of a frame built on soft soil under seismic excitation taking into account soil-structure interaction. First, was evaluated using finite element method, then, by substructure method which modelled springs and dampers in linear nonlinear study. Rheological models were determined impedance functions, calculated numerical program CONAN. These dynamic impedances ar...

Structural engineers commonly design superstructures as fixed at the base and transmit reactions to infrastructure in order foundation system estimate displacement of soil while disregarding change seismic response that this induces. In article, was transformed into equivalent springs, linear range compared quantified, obtaining results such increased periods, amounts steel reinforcement beams ...

Soil - structure interaction behaviour of pile foundation is complex for heavier structures which suffer large lateral load due to wind, wave action etc., in addition the vertical and oblique load. The parameters involved determining capacity are its structural geometry, soil properties ground condition. different horizontal compared sloping ground; it even under loading unloading conditions. I...

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...

SSI and site amplification effects are investigated as influences on the seismic fragility of existing reinforced concrete moment-resisting frame dual frame-wall system buildings supported shallow foundations without interconnecting beams. We build upon a holistic methodology that accounts for soil–foundation–structure interaction using modular approach. calculate curves based nonlinear dynamic...

Abstract Until recently, the behavior of connected piled raft foundation was not fully understood in seismically active region due to complex dynamic soil–pile–foundation structure interaction. This concern arises when soil deposit-supported foundations are stratified or heterogynous and subjected high ground motion intensity. In current study, a series numerical analyses using ABAQUS software ...

In common buildings the soil-structure-interaction (SSI) is governed by the elastic behavior of the building. The best conditions to see the soil effect predominate would be a dynamic rigid body movement of a massive building. For this reason measurements were carried out on an old anti-aircraft tower from World War II on typical Viennese soil conditions. The dynamic properties of the soil coul...
