FEASIBILITY STUDY OF CFRP CONFINED RC DRIVEN PILES SUBJECTED TO VERTICAL LOADS- NEW CONSTRUCTION METHODOLOGY

Pile foundation is a popular form of deep foundations which is widely used for both land based and water front structures. Piles are generally adopted for structures in weak soils characterized by low shear strength and high compressibility and in case of structures which are subjected to heavy loadings and moments. Load carrying capacity of CFRP confined and unconfined piles were found out using the dynamic formulae and pile load test. Safe load carrying capacity of piles determined from piles load test was slightly higher than the dynamic formulae. The experimental result also shows that surface roughness of specimen is significantly changes the interface friction angle. The shear strength at the interface increases with the increase in surface roughness of the specimens.
