Using the wave forces obtained from ANSYS AQWA, the structural analysis of the gravity substructure for 5MW offshore wind turbines is carried out through ANSY Mechanical. Moreover, the comparison of natural frequency between the wind turbine and the gravity substructure is made to investigate the resonance. It is found that the suggested gravity substructure can be an effective substructure for 5MW offshore wind turbines.

To evaluate the prestressing loss of tendon caused by deflection angle, test is conducted with the variables of a deflection angle and a diameter of deviator head. Results show that the prestressing loss increases when the delfection angle increases but the diameter of deviator head gives no significant influence on the prestressing loss.

As the weight is increased by the quantity and size of the members in large scale structures, precast column-beam joints should be designed in consideration of the assembly process. This paper was presented a way to reflect the construction difficulty such as interference of rebar at the end of beam when you design rebar joints and calculation of the length of the embedded steel.

This study aims to apply multistage homotopy perturbation method (MHPM) to SDOF space truss to obtain a semi-analytical solution. For the purpose, a nonlinear governing equation is derived in consideration of geometrical nonlinearity, and homotopy equation is formulated. The result of carrying out dynamic analysis on a simple model is compared to a numerical method of 4th order Runge-Kutta method (RK4), and the dynamic response by MHPM concurs with the numerical result.

Semi-rigid pavement is one of excellent paving methods adopting merits of asphalt-concrete and concrete paving. However, conventional paving methods were mainly used on the new constructed roads. Therefore, in this research we have examined the possibility of using the semi-rigid pavement on occupied roads. Also, confirmed the early-open possibility of pavement by applying the rapid hardening binding material to semi-rigid pavement.

This study investigates engineering characteristic of recycled aggregate concrete which incorporated various amount of recycled aggregate(0%, 30%, 50%, 100%). For the purpose of the investigation of engineering characteristic, compressive stress and air content, slump were evaluated. Evaluated results of compressive stress was shown that compressive stress and slump decreased depending on amount of recycled aggregate increased. On th other hand, air contents increased depending on amounts of recycled aggregate decreased.

The purpose of this paper is to establish specifications, to provide design database for the construction of the sea pools(30m x60m x 1.2m). When water overflows by high waves, 3D-analysis by SAP2000 software is required for designing of sea pools in order to settle the problems that the degradation of the concrete durability.
This result of analysis show that the strngth of concrete over 60MPa and the distance of 4m plie is more advantageous, then that of 2m.

The demand of underground structure such as box culvert for electric power transmission is increasing more and more, and the service life extension of these structures is very important. Then, the service life due to carbonation at the cover depth was calculated by in situ information and the Monte Carlo simulation in a probabilistic way. Additionally, the accelerated carbonation test for the cracked beam specimen was executed and the crack effect owing to the carbonation process on the service life of box culvert was numerically investigated via Monte Carlo simulation based on the experimental results.

In this study, using the general-purpose structural analysis program, prediction of thermal crack of ultra-high-strength concrete(UHSC) columns were investigated. Parameters were column shape and column size of UHSC columns that have higher temperature rise than normal strength concrete. Thermal crack behaviors according to UHSC column shape were investigated.
