Tensile forces loss of pre-stressed concrete member will occur with various causes. However, there are differences between calculation results introduced by design code and test results. It is important to reduce the number of errors. In this paper, we suggest measuring of tendon strain from jacking stage. The careful placement plan of strain gauge for PS strand should be considered because of twisted tensile behavior. Later, the experimental investigation would be conduct to make an accurate estimate of tensile forces loss.

In this study, the strut-tie model used for the analysis and design of the anchorage zone of the PSC modular bridge by comparing with the result of the approximate analytical method. The result shows that the bursting force obtained by approximate analytical method were increased about 2 times in comparison with the result of strut-tie model.

In this paper, we present the results of investigations pertaining to the structural behavior of egg-shaped pipe buried underground. Mechanical properties of pvc sample taken from the egg-shaped pipe are tested according to KS M 3006. Test results are used in the finite element simulation for the structural behavior of the egg-shaped pvc pipe buried underground. Maximum stress obtained at the pipe is compared with the maximum strength of pvc pipe material. It was found that the egg-shaped pvc pipe buried underground is safe.

Steel panel dampers are very economical, easy to maintain and widely used as vibration control devices for building structure. However, this dampers are fractured in the center part under repeated loading so that the strength degrades after attaining the maximum resisting capacity. This issue and other many problems had been pointed out by many researchers. In this paper, the performance of steel panel damper has been enhanced by introducing cover plates on the panel on both side so that the lateral out of plane buckling of panel was protected. Thus, the deformation behavior as well as its hysteretic characteristics of a newly proposed Out-of-plan buckling resisting steel damper (BRSD) were studied

The purpose of this study is to develop structral technologies on the lightweight composite slab systems with sound reduction layers in the modular house. In this study, two kinds of slabs with minimum thickness was suggested reducing the floor impact sound. In order to evaluate the structural performance, the flexural strenth tests were carried out on the one-way full scale specimens. From the results of test, we know that the proposed slabs had ductile behavior and would be safe sufficiently.

Even though installing measuring device for safe structure became duty because of structures’ becoming larger, the battery replacement of sensor node is difficult when it is hard to approach such as specific bridges.
This study was done for the examination of the activating possibility wire accelerometer after converting vibration energy occurred from sine wave (±0.2g) to electric energy with cantilevered piezoelectric energy harvester when it vibrates continuously.

To evaluate the decline of the strength and energy dissipation capacity of RC moment frame, which proceeded with corrosion of the reinforced-bar of the element, simulation test is conducted with simulation model which adopted monte-carlo simulation method. For the design of damper, the strength, stiffness degradation and energy dissipation capacity are evaluated by using test results.

Experimental observations and theoretical predictions were presented for a total of 8 reinforced concrete wall with all sides being exposed to ISO standard heating curve. In the modeling of wall axial deformation under constant load at varying elevated temperature conditions, numerical models on heat transfer and spalling were considered along with the mechanical model. Based on the model, preditions on the fire resistance of the bearing wall under the axial load was presented.

The objective of this study is to develop the reinforcing design method of the NPP (nuclear power plant)'s steel plate concrete (SC) wall for enhancement of impact resistance capacity under the aircraft and missile impact loading considered in the design of NPP's facilities. This study investigated the effects of the several parameters that can affect impact resistance capacity of SC wall using finite element analysis method.(e.g., thickness of concrete and steel plate, material strength of concrete and steel, and other reinforcing design method).

This test is accomplished by one for performance evaluation of FRP which takes center stage for new material recently. generally, FRP is CFRP, AFRP, GFRP which are high tensile rebar and light material than steel reinforcement. Therefore, the research about the long-term performance assessment of FRP is needed. we performed fatigue test in this study as part of the test.

This study is to evaluate fatigue resisting capacity of insulated sandwich wall panel under wind-induced fatigue loading. The fatigue loading is calculated based on the probability distribution function (Weilbull and Rayleigh). The serviceability of the insulated sandwich panel was evaluated subjected to the probability-based fatigue loading.

Construction period is one of the most important factors which influence on cost and quality in nuclear power plant construction. As part of continued efforts for the competent reactor type, a dome liner plate module in the reactor containment building is developed to minimize the construction period. This study referred to knowledge and experiences from APR+(Advanced Power Reactor Plus) technical development. The proposed method can be applied to the APR+ in the near future.

The results presented in this paper also provide a summary of an experimental investigation, in which reinforced concrete beams were strengthened with carbon fiber sheets and subjected to fatigue loading. The comparison shoes that the analytical modal provides reasonably accurate prediction of deflections. Although carbon fiber composites were used for the evaluation, the modal is also applicable to other types of fibers.

This study presents the seismic evaluation and prediction of post-retrofitted piloti-type reinforced concrete building with buckling-restrained braces (BRBs) under the successive earthquakes. For seismic assessment before and after retrofit of the BRBs, the fragility analysis is considered. The fragility relationships for the damaged building between ground shaking intensity and damage probability were derived under the successive earthquakes.

On the steel pylon base, prestressed anchor bars and high-tension bolts, exposed on corrosion environment, can cause delayed fracture. And because of the large wind forces, it really need in-depth structural analysis for the steel pylon base section. The purpose of this study is to suggest the design improvement based on the structural nonlinear analysis.

This study seeks to characterize the dynamic behaviour of each section and to understand the performance of the interface using centrifuge model test and numerical analyses. The model test was verified by the comparison of the test results with those of numerical analyses, and the natural frequency for the composite dam with concrete-rockfill was proposed as like the same centrifuge model test and numerical analyses.
