| For prestressed reinforced concrete structures, cracking is allowed at the serviceability limit, and the crack width should be controlled by deformed reinforcing bars and prestressing forces. There are many research results relating to the flexural crack widths in RC beams; however it is not clear in PRC beams especially the effect of creep and drying shrinkage on their crack width. Experimental study using PRC, RC and PC beams are carried out to investigate it. In this paper deformation and crack widths of PRC beams under the sustained flexural load will be discussed with the data of creep and drying shrinkage of concrete without reinforcement. |
