This paper presents a study on the construction method of modular pier system using CFTs. Modular Pier System consist of various prefabricated modules and is constructed by assembling components. Research scop include development of standard modules for adjustable to various height, connection between modules, and test bed construction. For the evaluation of this systems’s performance, Many numerical and experimental studies were conducted. In this study, we develop rapid construction system for site application of modular pier.

In this study fatigue test on the steel grid composite deck is conducted for the evaluation of fatigue performance and serviceability. Deflection and crack width are measured at the end of each cyclic loading step. Test results show that maximum measured deflection and crack width are below the allowable values, and the tested steel grid composite deck exhibit acceptable fatigue performance and serviceability.

Bending test on the steel grid composite deck under different loading conditions are conducted for the evaluation of flexural behaviour. 1m wide two decks are connected by prefabricated joint. The Joint is composed of concrete shear key and high-tension bolts. Test results show that deck subject to concentrated centric loading has greater load bearing capacity than deck subject to eccentric loading because the deck subject to centric loading has larger effective width.

This paper concerns the flexural behavior of hybrid steel fiber-reinforced ultra high performance concrete (UHPC) beams. It presents experimental research results of hybrid steel fiber-reinforced UHPC with steel fiber content of 1.5% by volume and steel reinforcement ratio of less than 0.02. The comparison of moment-curvature curves of the numerical analysis results with the test results shows a resonable agreement.

the primary objective of this research is to reduce the damage of critical frame structures such as hospitals and schools during and after an earthquake. this study develop the infill panel to allow smaller shear deformation with sliding of the specific element in the panel. As a result, the side sway was significantly reduced in the structure with infill panel, in comparison to the steel frame structure without infill panel during the experimental test

In order to evaluate the seismic safety of weir structure subjected to seismic ground motions, Non-linear elastic 2D plane strain Finite Model (FE) was developed in ABAQUS. Also, the 1994 Northridge earthquake as a ground motion uncertainty was selected. The numerical results show that the tensile stress was increased with increase the friction coefficient

The purpose of this study is to analyze the trend of domestic and foreign steel plate shear wall (SPSW) systems. The investigated countries were three, such as Korea, Canada, and U.S. The full scale or scale down specimens were preponderantly investigated. The details and performances of all specimens were compared for each other.

This paper indicated the seismic performance evaluation of coupling beam designed by ACI 318 11 and SFRC(Steel fiber reinforced concrete). In this study, SFRC coupling beam added steel fiber of 1.5 %. Teste results indicated that coupling beam reinforced by SFRC shown outstanding absorb energy capacity and stiffness degradation than concrete coupling beam by bridge effect of steel fiber.

This paper describes the effect of steel frame on seismic performance of non-ductile reinforced concrete (RC) frame. To achieve the this objective, RC frames were made based on existing school building constructed in 1980s. Test results indicated that RC frame retrofitted with steel frame was improved the seismic performance than conventional RC frame.

In this study, cyclic loading tests of cantilever rectangular reinforced concrete columns were performed to evaluate the seismic performance of relatively short lap splices with non-seismic hoop details. The lap splice length of 30 times diameter of longitudinal reinforcement (30) with the hoop spacing of a half of effective column depth(0.5) showed adequate flexural strength and ductility even though smaller lap splice length than ACI318 was used in plastic hinge zone.

This study assesses the adequacy of a critical value of the FEMA 273 for beams utilized in the present performance-based design. From the comparison the critical values of FEMA 273 with those of previous experimental result about beams, it was shown that FEMA 273 underestimated the critical values. Therefore, it is necessary to perform a research to find the hysteresis model for the performance-based design considering the hysteretic behavior of domestic reinforced concrete members.

This study was evaluated of flexure strength and ductility of a V-tie arrangement method in reinforced concrete columns under a variable axial force. The axial load level varied to be 0.25, 0.4, and 0.55 for columns with V-ties or crossties. As compared with displacement ductility ratio and the work damage indicator of the companion crosstie columns, the V-tie columns had higher value as much as 1.5 times, 5.2 times for the axial load level of 0.55, respectively.

In the past, criteria and procedures for the design of concrete structures were primarily based on allowable stresses for structural components. However, it is now well recognized that the limit state approach is a better basis for design since it is difficult to determine the real safety margin of submerged structure.

Dynamically inelastic analyses on bridge columns were carried out based on the Korea bridge design code revised in 2010. To evaluate the effect of ductility demand-based analysis, rectangular and circular sections of bridge columns were selected. It was found that the analysis method shall be applicable to seismic evaluation for conventional structures as well as RC bridges.

In this study a hybrid energy dissipation device is developed by combining a steel slit damper and linear-slot friction dampers to be used for seismic retrofit of structures. The hybrid damper has an advantage in that friction dampers are activated for small earthquakes or strong wind while slit damper remains elastic, and both friction and slit dampers work simultaneously for strong earthquakes. Cyclic loading tests of the linear-slot friction, slit, and the combined hybrid dampers are carried out to evaluate their seismic energy dissipation capability.

In this paper, the vibration control effect of the exterior-installation Kagome damping syste (EKDS) was investigated by applying the Kagome dampers to a 15-story frame apartment building structure. The numerical analysis results of a structure with exterior-installation Kagome damping system up to the third story showed that the application story should be higher than second story to effectively reduce the base shear and the maximum drift of the uppermost story. When the exterior-installation Kagome damping system was installed up to the fifth story, the application story should be higher than third story and for obtaining the target performance.
