In the KEPIC-SNG, the domestic technical standard of the SC structure, the condition that the baseplate supporting the reinforcing bars is not bonded to the surface plate is suggested. However, if the baseplate is bonded only to the wingplate, all of the rebar loads generated on the baseplate will be transferred to the wingplate. The wingplate is expected to be conservatively designed in spacing and thickness to support the rebar load. In this study, the finite element analysis was carried out according to bonding conditions between surface plate and baseplate. As a result, it was confirmed that the overall structural strength was increased when the baseplate and the surface plate were bonded. Based on this result, it is possible to propose an economical design for the RC-SC connection such as increasing the wingplate spacing.

In countries that suffer from heavy rain such as Korea, bridges have to be prepared for a sudden water level increase. However, research on the flood risk assessment for bridges has gained less attention than earthquakes, even though one of the major causes of bridge failures has been reported to be flood. In addition, various sources of uncertainty make it challenging to evaluate the flood fragility of a bridge, and there have been few studies on the flood fragility curve derivation for bridges. The present study proposes a new methodology employing finite element reliability analysis to derive flood fragility curve. In the proposed method, two software packages, ABAQUS and FERUM, are connected so that reliability analysis can be performed in conjunction with sophisticated finite element analysis flood fragility assessment. The method is applied a real bridge in Korea, and flood fragility curves are derived for multiple damage states.

In this study, we conducted a finite element analysis of the behavior of the main part, and aimed to check the compliance of allowable stress.

In this paper, the peak impact factor response spectrum is verified through finite element (FE) analysis using a simply supported bridge. The FE model is a slab bridge designed with 4 m width and 8 m length. The FE analysis is applied on the bridge modeled with 2D frame and 3D solid. By considering 5% damping ratio, the peak impact factors of the FE models and the response spectrum are compared. From the results, a very small difference of about 1.5% is found between the FE models and the response spectrum.

Sewage Pipe Renewal (SPR) method rehabilitate pipeline by forming a PVC profile inside the pipe by using a winding machine without excavating the soil above the pipe which lowers the cost of the rehabilitation. This study will investigate the effects of varying the pipe’s diameter to its wall thickness ratio. The dimensions for the diameter and minimum wall thickness of the non-reinforced concrete pipe will be based from ASTM C14. The finite element analysis software, ABAQUS, will be used to model and perform the analysis for the composite pipes. To account for the soil-pipe interaction, soil springs will be used as the bedding support to hold the pipe in place. Additionally, three soil types will be used to compare the behavior of the pipe with different diameter to thickness ratios. The results from the finite element analysis will be shown in tables and plotted into graphs and a concluding remarks will be provided.

This study focuses on the effects of load height on the inelastic lateral buckling of doubly stepped I-beams. The effects of having compact and non-compact flanges are also covered by this study. Two sections are analyzed: one having compact flanges and web while the other section has a compact web and non-compact flanges. The loadings are limited to those having an inflection point of zero. Also, the three main locations for the loads analyzed would be at the top of the flange, at the shear and at the bottom flange. The nonlinear analysis is done using the finite element program, ABAQUS. Also, to take into consideration the effect of inelastic buckling, residual stresses and geometric imperfections are applied to the models made. The results of the analysis would then determine if the location of the loads has significant effects on the buckling strength of the stepped beams. Also, the results are compared to the results of previous studies involving the effects of load-height on prismatic beams. The final results are tabulated and conclusions and new design methods are provided.

This study analyzes the buckling safety in the area of circumferentially edge-stiffened door openings without any additional longitudinal stiffeners of offshore tubular steel towers.

철도차량에 의한 진동은 지반을 통해 주변 지역에 영향을 주고 피로균열등 구조적 손상을 주고 있다. 본 논문은 새롭게 개발된 탄성 스페리컬 받침을 기존 강재스페리컬 받침과의 비교를 통한 진동저감성능에 대해 평가하였다. 탄성스페리컬 받침은 반구형 곡률과 크기를 변경함으로써 현장 여건에 맞는 강성을 구현할 수 있는 장점이 있다. 탄성 스페리컬 받침은 반구형 고무 및 보강판의 적층 받침으로써 성능특성을 확인하기 위해 설계와 해석결과를 비교하고 특성시험을 실시하였다. 또한 진동저감성능 확인을 위해 열차의 실대차 축소모형 시험을실시하였다. 해석적 검증비교를 통한 특성시험에서는 설계하중 500kN 시험체의 압축 및 회전 시험결과 압축보다 회전에 의한 강성 증가가적은 것으로 확인되었다. 또한 압축 및 회전 시험 후 시험체에 외관변형 및 영구적인 손상, 찢어짐 등은 발견되지 않았다. 축소 스케일 진동측정 시험에서는 실대차 모형을 1/50축소하여 교량의 진동을 측정하였다. 그 결과 강재 스페리컬 받침에 비해 탄성 스페리컬 받침의 진동저감능력이 탁월한 것으로 판단되며, 거리별 진동감쇠 성능도 높은 것으로 확인되어 탄성스페리컬 받침의 철도교 적용 시 진동저감효과가우수할 것으로 판단된다. 향 후 실제 철도교량에서의 현장실험을 통해 성능을 검증할 계획이다.
