Traditional marine structures are difficult to construct under the marine environment. These structure have maintenance costs associated with the chloride attack environments. In this paper, a new structure system is proposed to overcome these disadvantages. The connection of precast reinforced concrete girders and bent cap is the main feature of the proposed structure system. To assess the joint performance of the proposed methods, full-scale joint was fabricated and tested under cyclic loading. The key parameters examined were the pile displacement; the strain in the reinforcement; and the crack patterns in the concrete. The test structure behaved stably for cyclic loading. The test structure is analyzed to be safe in all members.

The objective of this study is about hollow core slab with GFRP (Glass Fiber Reinforced plastics) Reinforcing bar instead of using deformed bar. This experiment is planed because using GFRP Reinforcing bar instead of tension bar in existing RC hollow core slab will improve not only on the constructability but also on the durability by solving the corrosion of slab. As the result of the experimental study, GFRP Reinforcing bar and additional deformed bar appear to be superior compared to RC hollow core slab in structural ability.
