Expansive soils shrink and swell with drying wetting cycles. The shrink-swell capacity of expansive can result in differential movement beneath foundations which is a very common cause foundation problems. Ribbed slab, often called waffle one the efficient inexpensive solutions for use under light structures resting on soils. This paper presents numerical analysis that used to calculate displac...

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...

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 this paper, the influence of foundation configuration (raft or separate footings) on tunnel–soil–framed building interaction is investigated using geotechnical centrifuge testing. Tunnelling-induced soil movements and deformation fields, framed displacements structure shear distortions (with associated modification factors) are illustrated. Framed stiffness footing bearing capacity also eval...

The use of piled raft foundation in building and infrastructure constructions is increasingly popular because its effectiveness reducing overall differential settlements. Parameters influencing the performance need to be comprehended order optimize design system. Most current available literature focused on subjected a uniform distributed load sandy material. This parametric study aims provide ...

In order to get a more safety and economic foundation, finite element method was performed for piled mat cap strip by the software of STAAD. Through analysis, plate distribution region bending moment shear stress were researched; meanwhile, considering compatibility deformation plate, how chose design value researched. The result showed that: single is not representative, average 9 plates (3x3 ...

Abstract The main problem of road construction on saturated soft soils is due to their low bearing capacity and large settlement. One the solutions such problems install piled box culverts-geofoam. In this study, pile culvert-geofoam was modelled as raft foundation. This experimental study conducted by making a prototype file foundation gradually loaded with maximum vertical load 20 kN. Differe...

In this work, based on experimental observations and exact theoretical predictions, the kinetic scheme of RAFT polymerization is extended to a wider range of reactions such as irreversible intermediate radical terminations and reversible transfer reactions. The reactions which have been labeled as kinetic scheme are the more probable existing reactions as the theoretical point of view. The ...
