A comparative study of soil-structure interaction in the case of frame structures with raft foundation

Abstract

Design and modelling of raft foundations and selecting the value of coefficient of vertical subgrade reaction are still actively discussed topics in geotechnical and structural engineering. In everyday practice, soil–structure interaction is mostly taken into account by using the theory of ‘beam on elastic foundation’, in which the soil is substituted by a certain set of coefficients of subgrade reaction. In this study, finite element analysis of a building was performed using a geotechnical software (Plaxis 3D), which is capable of modelling the subsoil as a continuum, and a structural software (Axis VM), which uses the concept of ‘beam on elastic foundation’. The evaluation of the results and recommendations for everyday engineering practice are introduced in this paper.

3D Numerical Modeling of Large Piled-Raft Foundation on Clayey Soils for Different Loadings and Pile-Raft Configurations

1 Introduction Piled raft is a geotechnical foundation consisting of three elements raft, piles, and soil domain. The piles can be used to reduce the settlement of the raft foundation (Burland 1977). Also, several studies suggested that the piles in piled raft can be used to carry some part of the superstructure load. The distribution of among load among the piles, raft, and soil depends on their relative stiffness. On the basis of the dimensions of the raft and piles, the piled raft can be classified as a small piled raft ( B r < L p ) and large piled raft

Seismic Base Isolators For A Silo Supporting Structure

Abstract

A 3000 tones capacity silo, located in a seismic area with ground acceleration ag = 0,20g and TC =1,0s, was designed in a classical solution The supporting structure has an octagonal shape in planview, and columns with “Maltese cross sections”. The main lateral resisting system is made up of centric bracings with cross-section class I.

The technological project has required two silos and the solution was to support them on a common raft foundation. The stresses and strains due the seismic action led to material consumption that exceeded the agreed budget. In order to reduce the costs, two versions of isolator positions were studied: base isolators (at the connection between infrastructure and superstructure) and at the silo’s bearing level on the supporting structure.

A number of eight vertical seismic isolators were used and in order to limit the horizontal displacements due to wind action and for small intensity earthquakes special devices were introduced

Comparing the state of stresses and deformations and also the cost analysis regarding the positioning of the isolators, the second solution was chosen as the most feasible.
