The behaviour of sleeve connection with spiral reinforcement and additional longitudinal bar under direct tensile load

One of the important precast concepts is all the precast elements must be connected for the stability. Therefore, the connection systems of the precast concrete structure must be designed in such a way that its structural performance is equivalent to that of a monolithic concrete structure. In most...
