Abstract Large-scale risk analysis is typically performed considering existing fragility curves, calculated in most cases without adequately accounting for local site amplification (SAmp) and soil-structure interaction (SSI) effects. Nevertheless, foundation flexibility effects may lead to a substantial difference the or loss estimates. Including these on city-scale vulnerability challenging du...

Heritage structures are an important part of the history each community as well economic resource. This study aims to investigate earthquake damage and failure mechanism a historic Bazaar located in Kashan (center Iran), which dates back eighteenth century. Numerical models were built by macro method, considering two cases fixed support soil–structure interaction (SSI). To assess structural beh...

Tuned  mass  dampers  (TMDs)  are  as  a  efficient  control  tool  in  order  to  reduce  undesired vibrations  of  tall  buildings  and  large–span  bridges  against  lateral  loads  such  as  wind  and earthquake. Although many researchers has been...

Industrial structures built with different materials and methods play an important role in the sector development of industry increase energy need. Many parameters are considered design application phase industrial to provide service for many years. The aim this study is examine dynamic behavior reinforced concrete chimneys depending on soil-structure interaction (SSI). For reason, a chimney, w...

The response of structures bonded to the surface of a transversely isotropic half-space (TIHS) under the effect of time-harmonic forces is investigated using a coupled FE-BE scheme. To achieve this end, a Finite Element program has been developed for frequency domain analysis of 3D structures, as the first step. The half-space underlying the structure is taken into consideration using a Boundar...

Subsea high pressure/high temperature (HP/HT) pipelines may be significantly affected by the effects of soil structure interaction (SSI) when subjected to earthquakes. Numerical simulations are herein applied assess role deformability on seismic vulnerability an unburied pipeline. Overcoming most contributions existing in literature, this paper proposes a comprehensive 3D model system (soil + p...

the interactive effects of adjacent buildings on their seismic performance are not frequently considered in seismic design. the adjacent buildings, however, are interrelated through the soil during seismic ground motions. the seismic energy is redistributed in the neighboring buildings through multiple structure-soil-structure interactions (sssi). for example, in an area congested with many nea...

starting from two-dimensional (2d) equations of motion, discretized formulations for transient behavior of soil-structure interaction problems have been derived. two different dynamic infinite elements taking into account single and two-wave types are presented in transformed space. by coupling the infinite elements with standard finite elements, an ordinary finite element procedure is used for...

In practice, the slab foundation is used widely in civil engineering. Besides concrete material, fiber applied more popular foundations. Determining ultimate load of foundations a complex problem due to relation soil-structure interaction (SSI) problem, which depends on both structures and subsoil characteristics. ANSYS finite element software reliable effective technique simulate structure mod...
