Abstract:For better durability and more rapid construction of reinforced concrete marine structures, the authors designed composite beams that consist of channel-shaped precast concrete forms reinforced with FRP and inner reinforced concrete. In this study, static flexural and shear tests were conducted to ascertain basic mechanical properties and estimate design methods of these types of beams. The flexural capacity coincided well with the values calculated by a conventional design method. The shear capacity was calculated on the conservative side by 20 to 30 percent by using the Niwa equation. No dislocation occurred between the form and inner concrete up to the level of the design load. However, dislocations were observed between them at shear stresses of more than 22 kgf/cm 2, and therefore shear connectors (studs) were needed for their prevention.
