This study analytically reviewed the behavior of Steel Plate Concrete(SC) walls subjected to cyclic shear forces to investigate the effects of shape and arrangement spacing of studs on the design of SC walls. The shape of the stud did not affect the shear behavior of SC wall but, the spacing influenced to its composite action.

본 연구의 목적은 고강도 SFRC 보의 강섬유 보강효과를 평가하기 위한 것이다. 이를 위하여 13개의 실험체를 제작하여 성능실험을 실시하였다. 실험 변수는 전단경간비, 강섬유 혼입률, 전단보강근비이며 콘크리트 강도는 60 MPa이다. 기존 연구결과와 재료 및 부재 실험결과에 대한 분석에 의하면, 전단경간비 2.5와 강섬유 혼입률 1.0%인 경우가 강섬유 보강효과가 최대로 발휘되는 것으로 평가되었다. 강섬유 보강 및 전단경간비를 고려한 기존 전단내력식은 고강도 SFRC보의 내력을 과소평가하는 것으로 평가되었다. 향후 고강도 SFRC 보의 강도특성에 대한 보완 연구가 필요한 것으로 판단된다.

In this study, experiments are conducted to investigate the physical features of insulated CSP with GFRP shear connectors with varying shape and specification of GFRP shear connectors, and types of insulations. Test results indicate that developed GFRP shear connector has a significant effect on structure performance of insulated CSP.

Specimens designed by the interior beam-column joint regions without the shear reinforcement of existing reinforced concrete building showed a unstable mode of failure and an decrease in load-carrying capacity and energy dissipation capacity and ductility ratio.

This paper provides Shear Performance Evaluation of Squat Shear Wall on Aspect Ratio of Slit. The main variables of paper were vertical slit and slit length. Slit height analysis results by lengthening the slit height was reduced according to the strength and stiffness, the maximum displacement was increased.

In order to apply a mechanical deck joint to the prefabricated steel gird composite decks, shear resistance of a joint composed of concrete shear key and high-tension bolt is experimentally evaluated by the push-out test. In comparison with resistances estimated by empirical and design equations, the deck joint can be safely designed. But because the existed shear resistance of deck joint is underestimated by the ACI-318, application of the LRFD design equation could be more reasonable.

To assess the deformation capacity and structural performance of shear walls, slits and steel fiber was used as a variables. The experimental results show that steel fiber reinforced concrete shear wall is superior compared to normal reinforced concrete shear wall. The experimental results of shear wall with slits is too.

In this study, to Assess the Structural performance of Reinforced Concrete Shear Wall with different Slit Length. Variable of analysis is slit length(0, 600, 1200, 1500, 2400mm), showed excellent accuracy. Maximum load is decreased when the slit length increased. But Side sway of maximum load is increased when the slit length increased.

A new type of GFRP shear reinforcement is proposed for reinforced concrete beams. The new GFRP shear reinforcement consists of GFRP plate material with openings to ensure complete integration with the concrete. The performance of the proposed shear reinforcement was investigated by performing tests on six concrete beam specimens with shear span-to-depth ratio of 2.4. Test parameters include the area of opening of GFRP plate and the shape of GFRP plate. The effects of these parameters on the shear strength of the GFRP plate shear reinforced concrete beam were examined.

The GFRP shear reinforcement is manufactured into a plate shape with several openings, and it is embedded into concrete with longitudinal steel reinforcements during construction stage. In this paper, the performance of the newly proposed shear reinforcement was investigated by carrying out a structural test on four concrete deep beam specimens. Test parameter is shear span-to-depth ratio, and the cracking pattern, failure mode and the effects of this parameter on the shear strength were examined.

To define the shear reinforcing effect of steel fiber in high strength concrete, 4 column specimens designed with a volume fraction of steel fiber such as 0.0%, 1.0%, 1.5%, 2.0%. The column specimens were tested lateral cyclic load under constant axial load. From test results, steel fiber can reduced brittle shear failure, and can increased strength and ductility capacity in RC columns.

In this study, experiments were performed in order to evaluate the concrete breakout strength of shear reinforcement considering anchorage type and embedment depth. and Using the result, we provide basic data for the design of shear reinforcement. According to the experimental results, If the concrete strength is relatively low and thin flat plate, we need a design considering the concrete breakout failure than concrete bearing failure.

The PHC pile offers high compressive strength, resistance to bending moment, economic efficiency and many other benefits. Being vulnerable to lateral force, however, it can only be applied in limited situations in which the strong lateral force doesn't need to be put in place, thus requiring the development of new forms of pile. For this reason, this study produces a concrete-Infilled Composite PHC pile(ICP pile) reinforced with shear reinforcement and ilfilled concrete and conducts a shear test according to KSF 4306.

Coupling beams of coupled shear wall systems are often the most critical members in medium or high rise buildings subject to seismic load or wind loads. To ensure the survival of shear walls under high-intensity cyclic loading, these beams, which normally have limited dimensions, should possess high deformability and good energy absorption while being able to resist large shear force. Experimental work are conducted to illustrate the design of special RC coupling beams using the proposed procedure reinforcement details.
