Fatigue crack can be a controlling factor in the life of some welding components, such as vertical and horizontal stiffener. In this study, The fatigue tests were carried out on the out-of-plane gusset fillet welded joint. In addition, investigations of three-dimensional fatigue crack propagation of gusset welded joint using the finite element analysis of FEMAP with NX NASTRAN and FRANC3D. The 3D crack growth simulations can be performed to compute stress intensity factor(SIF), which are used to determine crack propagation cycles.

In recent, high performance concrete structures can be developed using Ultra-High Performance Concrete (UHPC) which has mainly high compressive and tensile strength. Therefore, in reinforced concrete (RC) structures, it is possible to reduce structural elements and the cost of construction by reducing the amount of concrete and steel bars. This study compared and evaluated bending performances of RC and UHPC beams respectively and examined the design suitability of UHPC flexural members.

This paper presents a half-precast composite concrete slab using a strain-hardening cementitious composites (SHCC). The flexural characteristics of SHCC-RC Composite slab was evaluated with a conventional reinforced concrete slab and the composite slab was excellent in crack control to compare with the reinforced concrete slab.

Reaction degree of ground granulated blast furnace slag(GGBFS) in cement paste was measured by water-binder ratio and GGBFS replacement ratio, curing temperature with ages using selective dissolution. In result of experimental, when water-binder ratio and curing temperature were high and replace ratio of GGBFS was low, reaction degree was estimated high.

In this study, experimental research was carried out to evaluate the structural performance of the reinforced concrete beam retrofitted by strengthening methods(embedded CFRP rod of hexagon, CFRP Sheet) in existing reinforced concrete buildings.
Test results showed that the maximum load carrying capacity of retrofitted specimens(NER2, NER2-C) were increased by 1.46 ~ 1.67 times respectively in comparison with the standard specimen(NBS).

In this study, we intended to estimate the heat of hydration of carbon nanotubes-cement composites. It was tried to present the basic data of the heat of hydration characteristics of the CNT-reinforced cement composite by the simple adiabatic temperature rise test. The results indicated that adding CNT reduced the heat of hydration of cement composites.

In this research, a total of seven specimens were tested under reversed cyclic loading, controlled by displacement and three times of reversed loads were given at each displacement. The goal of experiments is to identify the seismic and structural performance of pure dry precast concrete beam-column joints using bolt type connection and/or prestressing methods. Two representative results are examined and compared in this paper.

In this study, the investigation of the local damage evaluation method for the SC structure subjected to impact load was carried out. The conventional RC formula and SC formula to calculate wall thickness to prevent perforation were studied and compared. Finally, these results were compared with finite element analysis results using LS-Dyna, and the future direction to develop the reasonable local damage evaluation method of the NPP SC structure was suggested.

The purpose of this study is to evaluate the seismic performance of unreinforced masonry(URM) building more accurately. For that, the nonlinear hysteresis models of preceding research did not validate for dynamic analysis. Therefore, in this study, we compared the results of the shaking table test and dynamic analysis. As a result, nonlinear hysteresis models are expected to be applicable.

The polar crane module in the reactor containment building has been reviewed to reduce the construction period and the workload on high elevation. In this paper, a numerical analysis for a lifting lug of the polar crane module was performed to confirm the structural integrity of the lug. The numerical analysis was also performed to check the structural integrity of the polar crane module. In regards of installation process, the constructability of the polar crane module was reviewed as well. Consequently, it is concluded that the reduction of construction period is possible.

Recently, a noise problem in the apartment has been broadly and socially issued. In this study, a numerical approach, i.e., vibration-acoustic interactive analysis, has been considered to investigate the relationship between damping ratio and the sound level in the apartment. From results, if the damping ratio has a range of 0 to 4 percentage, then the sound pressure level has been decreased. Finally, these results would be helpful to make a decision for developing of a high performance floor slab minimizing inter-layer noise.
