Response of Raft Foundation on Varying Stratum
نویسندگان
چکیده
The effect on raft foundation of a barrage due to varying stratum has been examined using finite element analysis. The raft foundation is completely resting on soil media and surrounded by soil and rock media. Eight noded brick elements have been used for three-dimensional modeling and meshing of the rock, soil, cut-off, pier, beam and abutment but raft foundation has been meshed using plate element. The relevant amount of soil and rock around and bottom of the raft foundation has been modeled to simulate the in-situ conditions. The raft foundation of a typical barrage has been analyzed using the representative load cases. Analysis of the barrage raft foundation has been carried out and the influence of soil properties has been studied at the region of transverse sections, which exhibited the response in terms of moments and deformation with significant difference.

A comparative study on pile group and piled raft foundations (PRF) behavior under seismic loading
Study on the seismic behavior of piled rafts and pile groups while the same amount of construction material and excavation is used in their construction, are the main objective of this research. The process where the raft interaction with soil can affect the seismic response and stress distribution is also discussed in the current study. By means, ABAQUS software was applied for the finite elem...
متن کاملBehavior of Piled Raft Foundation on Heterogeneous Clay Deposits Using Random Field Theory
In the case of problematic soils and tall buildings where the design requirements cannot be satisfied merely by a raft foundation, it is of common practice to improve the raft performance by adding a number of piles so that the ultimate load capacity and settlement behavior can be enhanced. In this study, the effect of spatial variability of soil parameters on the bearing capacity of piled raft...

In the recent years, non-connected piled raft foundation has been considered as an economical and practical deep foundation in the situation that high shear and concentrated loads may occur at the connection of the raft and pile head. This paper was presented an experimental study of a square foundation on the effects of parameters such as S/D, L/D and etc. in two cases of connected or non-conn...

In order to mobilize shallow soil to participate in the interaction of piled raft foundation sufficiently, the concept of piled raft has been modified to new type of foundation named composite piled raft. In the system of composite piled raft, the short piles made of flexible materials is used to strengthen the shallow soft soil, while the long piles made of relatively rigid materials is used t...
متن کاملGeotechnical Interaction of Piled Raft Foundations: Two Case Studies
Application of pile-raft foundations, which are known as “compound foundations”, is a suitable alternative in the case of heavy load structures. The interaction behavior of pile raft foundations makes these systems very complex to analyze. Different methods have been proposed to determine the bearing capacity of piled raft systems and distribution of loads between the components, i.e. pile grou...
