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...

The aim of the present paper is to evaluate the influence of the Soil- Foundation- Structure Interaction (SFSI) effects on the component demand modifier factor of concrete gravity beams based on ASCE 41-06 standard. To this end, the beam on the nonlinear Winkler foundation approach is employed which is a simple and efficient method. At first, four sets of 3-, 6-, 10- and 15-storey concrete mome...

An efficient and modular numerical prediction model is presented to predict vibrations and re-radiated noise in buildings due to metro trains. The approach comprises of three weakly coupled problems: the dynamic vehicle-track-tunnel-soil interaction problem, the dynamic soil-structure interaction problem and the calculation of the acoustic response inside the rooms. The three-dimensional dynami...

In existing buildings, it may be necessary to repair, adapt, renew, relocate or demolish buildings and building parts that have come the end of their usage period due spatial, functional, technical economic obsolescence. After applications extend service life is great importance analyze dynamic behavior under soil-structure interaction earthquake loads obtain accurate results. this study, seism...

regarding the importance of the prevention of hazards and adverse environmental impacts in industrial and populated areas such as southern parts of tehran city, the response of impulsive period ground-supported tanks were assessed. having considered the study area's soil properties, the response of ground-supported tanks was modelled. regarding the soil properties of southern parts of tehran, t...

numerical modeling of machining processes is of significance in the parametric analysis and optimization of their performance. in this paper, a finite element-based model of abrasive waterjet (awj) cutting of a ductile material is presented with the help of an explicit, nonlinear finite element method. in this model, both solid-solid interaction and fluid-structure interaction are considered. t...
