Flexural tests on epoxy-jointed precast prestressed concrete piles

The flexural behaviour of an epoxy-jointed precast prestressed concrete pile is discussed and compared with the performance of an unjointed pile and another pile with a welded joint. It is shown that the epoxy-jointed pile was capable of developing most of the ultimate capacity of the unjointed pile and had a stiffness comparable to the unjointed pile but higher than a welded jointed pile.
