유리섬유보강 철근콘크리트보의 내구력개선에 관한 연구 = (A) Study on the bearing capacity improvement of reinforced concrete beam byreinforced glass fiber sheets

다국어 초록 (Multilingual Abstract)

The buildings are getting deteriorated as time goes by. studies on steel Reinforced concrete beams and great interest in rehabilitation and repair are increased. But as yet domestic specifications on steel Reinforced Concrete beams and strengthening designs have not been made.
In this study, the structural strengthening of Steel Reinforced Concrete beams are evaluated by comparing internal shearing steel beams and no steel reinforced concrete beams. By making 13 test beams, glass fiber strengthening effects are examined in bearing capacity.
Strengthening effects are proportional to cross sectional area, which shows the presently performed steel Reinforced Concrete beam designs are over-designed.
in case of reinforced test beams, reinforced concrete beams and Steel Reinforced Concrete beams have 20% better flexural rigidify, strengthening effect than conventional ones.
