The use of optical fiber for measuring strain and or temperature is increasing in civil engineering. Optical known to be relatively cheap, compared the more traditional sensors commonly used, can, depending on chosen technology, give a complete distribution along instrumented element, which can very interesting case an element with variable dimensions length said element. Therefore, static pile...

This study aimed to investigate whether the seismic fragility and performance of interaction soil-pile-structure (ISPS) were affected by different parameters: axial load, a section pile, longitudinal steel ratio pile implanted in type sand (loose, medium, dense). In order better understand ISPS phenomena, series nonlinear static analysis have been conducted for two cases, namely: (i) fixed syst...

Pile foundations are relatively vulnerable to lateral loads. During liquefaction-induced lateral spreading, this vulnerability is particularly conspicuous due to a loss of strength and stiffness in the liquefied soil. A nonlinear effective stress analysis incorporating an elastoplastic constitutive model based on Finite Difference Method (FLAC2D program) was used to numerically simulate shake t...

The dynamic responses of pile–liquefied composite soils are complex, and the bearing capacities single piles or pile groups in liquefiable remain unclear. For friction piles, resistance determines vertical capacity pile. In a pile–soil system, it is very important to study changes during vibration. Based on shaking table test, this investigated foundation–liquefied soil system under simulated h...

It is proposed to use a single base platform in the Persian Gulf considering its low depth and more appropriate environmental conditions in comparison to North Sea and Mexico Gulf where this kind of platform is very popular. The pile of platform is responsible for transmission of environmental loads resulted from waves, currents, wind and dead loads to foundation of platform. Using SACS 5.3 sof...

To investigate the treatment effect of micro-piles on uplift deformation red-bedded soft rock subgrade, an in-situ static load test slurry injected steel pipe with different length was carried out, bearing capacity and characteristics were analyzed, transfer function pile lateral friction resistance modified consideration length. A numerical simulation method considering variable shear stiffnes...

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...
