Abstract
The purpose of this study is to propose an economic new type rib by applying plate stiffening methods of the corrugated plate and the honey-comb sandwich panel to the steel deck plate and comparing the new type rib with existing open and closed ribs. The trapezoidal corrugated type, ㄹ type, honey-comb type and ㅁ type ribs are considered as new type ribs and the moment and the steel volume are compared with that of open ribs and closed ribs. The results shows that the honey-comb type and ㅁ type ribs are good in aspects of economic feasibility and the ㅁ type is better than the honey-comb type. To make the ㅁ type rib applicable to the steel deck plate, the sensitivity analysis and parametric study are performed and the system to select the proper section under the particular stress condition is established. The closed rib of real bridges is compared with the ㅁ type rib of the proposed system and it is known that the new type rib is more economic. Therefore, more economic steel deck plates can be achieved by using the system proposed in this study for the plate stiffened with the new ㅁ type rib.
