Through conducting a comparative experimental study of small-aspect-ratio isolated structure models on multi-layered soft soil foundations and rigid foundations, this paper investigates the influence soil–structure interaction (SSI) effects seismic response structures foundations. An energy balance equation for systems considering SSI is proposed, impact dissipation analyzed in depth. The analy...

A three-dimensional finite element analysis was carried out for the influence of soil-structure interaction (SSI) on seismic response an isolated continuous bridge with a friction pendulum system (FPS). SSI modelled using soil resistance vs deflection nonlinear springs (following p-y curves). The dynamic behaviour and bridges different coefficients FPS were investigated six measured ground moti...

Modular expansion joints (MEJs) are used for accommodating large relative displacements of adjacent bridge segments and for completely eliminating pounding. However, the minimum total gap that an MEJ needs to avoid pounding is not well investigated. To provide guidance for the seismic gap of MEJs, the maximum relative displacement of adjacent bridge segments subject to strong earthquakes was st...

An investigation of Soil-Structure Interaction (SSI) effects on the seismic response Regional Administration building in island Lefkas, Greece is performed, based earthquake recordings from two accelerometric stations installed at basement and ground surface a certain distance structure, representing free-field station. The observed deviation between records explored by means hybrid numerical—a...

The structural damage due to recent seismic events in Nepal has led a dire need for studies considering soil-structure interaction (SSI) as the majority of designers still adopt conventional design principles. These damages may be result fixed base method’s failure take into account underlying soil properties. Post $$M_w$$ 7.8 Gorkha earthquake, revised National Building code NNBC 105:2020 clas...

As inferred from earthquake engineering literature, considering soil structure interaction (SSI) effects is important in evaluating the response of transmission line towers (TLT) to dynamic loads such as impulse loads. The proposed study investigates SSI on TLT behavior. Linear and non-linear models are studied. In linear model, represented by complex impedances, dependent frequency, determined...

It is conventional to assume that the role of soil-structure interaction (SSI) beneficial buildings under seismic loading. However, lessons learned from recent earthquakes revealed this assumption could be misleading, and SSI may have different effects on response structural systems. In study, an enhanced numerical model developed verified using ABAQUS software assess impact high-rise frame-cor...

This paper includes the investigation of soil–structure interaction (SSI) effect on seismic response 20 and 30-story reinforced concrete moment resisting frames (MRFs) rested a piled raft foundation using direct approach. After that, study is conducted to show impact cellular instead designed solid dynamic building. A introduced select best gap size for raft. The soil model assumed as single la...

This paper investigates the application of Artificial Bee Colony (ABC) method for the optimization of Tuned Mass Dampers (TMDs) employed for high-rise structures including Soil Structure Interaction (SSI). The model is a 40-story building, and Newmark method is utilized for the structure response to Bam earthquake data. The objective is to decrease both maximum displacement and accelerati...

it is well-known that the behavior of soil-structure systems can be well described using a limited number of non-dimensional parameters. this is the outcome of researches based on the premise that the foundation is bonded to the ground. here, it is shown the concept can be extended to systems with foundation uplift. a set of non-dimensional parameters are introduced which controls the main feat...
