CAP Deck의 시공중 구조성능과 처짐 성능 평가 = Structural Performance and Deflection Evaluation of CAP Deck during Construction Stage

다국어 초록 (Multilingual Abstract)

In this study, bending and shear experiments and large-scale mock-up tests were conducted to verify the structural performance and deflection performance of the deck with a thickness of 300 mm, 1.1 mm, and 1.4 mm to be applied to the long span structure during construction. The parameters of the bending and shear performance experiment were thickness and span and shear span, and the parameters of the large-scale mock-up tests were thickness, span, and installation of support. Bending and shear experiments tests results shows that nominal bending strength calculated by the effectⅣe width method was 92 to 96% of the bending strength. In addition, the shorter the shear width, the greater the strength was 1.17 to 2.58 times larger than the nominal shear strength. The large-scale mock-up tests was calculated by applying the effective section coefficient. Test results show that in 6.6m span (net span of 6.1m) at the final stage, 1.2 times larger deflection than that of calculated deflection occurred in the sand loading test and the concrete casting test, respectively. And these were 1.02 and 1.2 times in 8.4m span (net span of 7.9m) tests, respectively. strain values results shows that the deck was in an elastic range even at the final load stage of sand loading and concrete casting.
