One of the key issues in structural and geotechnical engineering is that most parts buildings are usually analysed separately then outputs used foundation designs. In this process, some effects neglected. study, soil–structure interaction (SSI) foundations concrete was evaluated using direct finite element method (DFEM). 3D models were developed to analyse with different stories constructed on ...

Soil-structure interaction (SSI) effects are usually omitted in the seismic vulnerability analyses of buildings. However, it has been proved that they might notably affect their performance. In fact, European codes establish should be included certain structures: with considerable second order (p-Δ) or mid/high-rise These characteristics shared by reinforced concrete (RC) buildings Portugal, wh...

In this paper, a dynamic analysis of an offshore wind turbine (OWT) considering soil structure interaction (SSI) is performed. The design these highly expensive structures tends to find the best compromise between cost and safety. To do so, coupling reliability-based optimization numerical model OWT required. An extension some RBDO methods such as Optimum Safety Factor (OSF), Hybrid Method (HM)...

The effect and behaviour of soil - framed-structure interaction (SSI) under dynamic load conditions are presented in the paper. All civil engineering structures involve various types structural elements that direct contact with soil. Hence, a new thin-layer interface element, based on concept finite element method, is formulated. formulation elaborated using combination degrees freedom top bott...

The Peak Ground Acceleration (PGA) is extensively used in earthquake engineering practice to describe the ground motion characteristics for establishing seismic vulnerability curves. However, a single parameter not enough excitation and does allow expressing complex relationship between structural damage movement. Motivated overcome these shortcomings, several ANN-based models were proposed pre...

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...

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...

Aboveground liquid storage tanks are often found on weak compressive soil due to their proximity harbours and rivers. These conditions lead a high probability of significant soil-structure interaction (SSI) under earthquake loading. In strong earthquakes, the transient partial separation tank base from supporting medium (uplift) chaotic sloshing cause damage wall. This experimental research det...

Abstract Simplified procedures, capable of predicting the main effects soil-structure interaction (SSI), involving minimum computational effort are desired in engineering practice. Besides, user-friendly approaches can be incorporated into guidelines or practical recommended procedures. Nevertheless, approximate solutions need to carefully validated through rigorous analytical numerical methods...

This paper investigates the influence of scour erosion on mode shapes National Renewable Energy Laboratory (NREL) 5 MW offshore wind turbine (OWT) in varying soil conditions, where modes are derived from and wave-induced accelerations. A numerical model, which considers aerodynamic hydrodynamic loading with soil-structure interaction (SSI) servo-dynamics, is developed. The superstructure modell...
