The results of an ongoing FEM parametric study are presented regarding the dependence of the resulting piled raft behavior under lateral load and combination of loads on pile diameter, pile length, arrangement of piles and raft thickness. Taguchi method with Analysis of Variance (ANOVA) was employed to calculate the contribution ratio of these factors on the lateral displacement of piled raft. ...

A Shallow foundation on cohesionless soil cannot support greater weights; piled raft foundations are recommended because they combine the load-bearing qualities of piles and raft. Combined Piled Raft Foundations (CRPF) efficient for tall buildings account both vertical lateral loads. In a pile foundation, raft’s load-resistance is disregarded due to soil-structure interaction. Simplification ma...

The present paper aims to investigate the effects of defective piles in horizontally loaded piled raft foundations. Close real scale foundation models and intact three-piled systems were submitted horizontal load tests. used bored type drilled with 5 m length 0.25 diameter, connected a concrete founded on tropical soil profile at University Campinas research site. Based experimental data, three...

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...

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...

numerous techniques have been presented by different researchers to analyze piled raft. in order to analyze pile foundation, soil can be modeled as spring, continuous medium, or porous media. pile can also be modeled as spring or continuous medium. this study includes three main stages: a short description of different types of analysis methods of pile foundation, writing a computer program bas...

Numerical modelling can simulate the interaction between structural elements and soil continuum in a piled-raft foundation. The present work utilized two-dimensional finite element Plaxis 2D software to investigate settlement, swelling, behavior of foundations during settlement swelling on various profiles under load combinations geometry conditions. field laboratory testing have been performed...
