Based on the study of chloride migration coefficient and hydration heat evolution, it was found that the use of ternary blended cement was effective to achieve desired service life and minimum crack index. On the other hand, a high level of compressive strength is required for marine concrete mix design.

Recently, the rotational solar tracker system is presented for the high electric efficiency. The horizontal rotation tracker is the structure for rotationg horizontally the most important part. However, it is difficult to secure the safety and maintenance in solar tracker systems. Therefore, this study suggests the reasonable structure type for horizontal rotational solar tracker through the strength reinforcement of the structure to ensure stability.

In this study, the experiments were carried out in order that flexural behavior evaluated High-strength Concrete Beams reinfrced with FRP plates according ro replacement ration of recycled aggregate. As a result, maximum load was higher than existiong of unreinforced when the reinforced with FRP plates and no decrease in load about increased fo replacement ration of recycled aggregate. Some specimens was greater than ACI 440-2R referemce value.

The goal of the study is to investigate vibration reduction effects in the ground due to the train-induced vibration using wave barriers. Rubber-based material has been selected for wave barriers and various barrier depths have been considered during numerical analysis. Result shows that the reduction effects are increased with proportional to the barrier depth, as one expected. Finally, results can be applied to design wave barriers for reducing transferred train-induced vibration to near structures.

A composite precast slab will be an economical alternative in case of constructing on a extremely cold region like antarctic. Side ratio optimization of the slab should be performed to solve the difficulties of using construction equipments and moving materials. Optimized side ratios by FEM and orthotropic plate theory are calculated and the results can be used to design the composite precast slabs.

The domestic research of the steel plate concrete structures have been focused on the nuclear structures that usually reqire large strength. This research tried to establish some basic design information of SC structures using non-cement concrete. This paper studied on the compressive characteristics, effective length factors subjected to the concentrated compression loadings. The effective length factors were calculated by Euler Column Theory rather than using Plate Buckling Theory. The strains which are requird in calculating the effective length factor were measured to caculate the effective length factor at the yield of surface steel plate, the buckling of surface steel plate and the failure of concrete.
