The Variety of Reaction at the Three Span Continuous Steel Box Girder Bridge under The Thermal Effect of Guss Asphalt

구스 아스팔트의 열 영향이 3경간 연속 강상판 박스 거더교의 반력에 미치는 영향

After the 1990's, Guss asphalt has chosen in Korea for using in pavement of a steel deck bridge because of it's distinguish ability about water proof and so on. But on the other hand it may cause server stress and displacement on the bridge as it is treated using very high temperature ranging from 220℃ to 260℃. Therefore it is critical to estimate the thermal effect of Guss asphalt on the steel deck bridge before the width and pattern of the unit portion are decided to minimize impact. In this study, a serious of numerical tests of the some steel box bridges were idealized were conducted to verify the feasibility of numerical value analysis. The parametric study was performed to present design proposal about the Box section dimensions and the diaphragm spacing.
