Concrete piles that were poorly constructed or analyzed in their soil analyses may have structural geotechnical defects. To examine such defects, an experimental study was conducted to investigate how a defective reinforced concrete pile behaved. These installed and subjected compression axial load the sand had relative densities of 30%,60%, 80%. The tests performed using four model piles: one ...

Abstract Slurry ratio is a crucial link in the construction of bored pile, which directly determines quality pile. In order to determine key performance parameters slurry required form piles deep sand layer, relying on Huizhou north station engineering, an orthogonal test proportioning was designed and carried out, SPSS statistical analysis software used carry out bivariate correlation multivar...

The AASHTO code of practice for design of bridges shows that the ductility level for foundation is given equal to one. Bridges are classified in three classes. For class of essential and normal bridges a question for not to use ductility level due to the importance of bridges’ costs is become an important item in different countries particularly in Middle east. This paper aimed to study on pe...

This paper examines the thermal resistances of energy piles and surrounding soils. A field-scale bored pile was installed through stiff sandy clay dense sand instrumented to measure temperatures on external walls heat exchanger pipes, at pile-soil interface, in soil. The radial temperature gradients between pipes interface soil, were used evaluate soil resistances, respectively. same order magn...

Abstract Model study was carried out in the laboratory to know effect of uplift loads on vertical piles, batter piles and pile groups. Mild steel having 22 mm outer diameter 1 thickness were considered for study. Different slenderness ratios 18, 28, 38 various angles such as 0°, 15°, 25°, 35°, 45° Sand poured at a fixed relative density mild tank. The experimental shows that group attain maximu...

Abstract Laboratory tests were carried out on non-piled rafts, single piles, surface contacting and non surface-contacting piled rafts which made of aluminum instrumented with strain gauges deflection gauges. The foundations installed in dry sand contained a large metal tank to minimize boundary effects. Maintained loads applied each foundation until failure was closely approached. In parallel,...

The offshore wind turbine (OWT) is a high-rise structure that extremely sensitive to dynamic loads such as wind, waves, and earthquakes. Therefore, in order avoid resonance, it important accurately calculate the natural frequencies of OWT at design stage. integrated finite element model DTU (Technical University Denmark) 10 MW established based on OpenSees software. correctness superstructure s...
