3경간 연속 중로식 강Arch 교량의 내풍안정성을 고려한 Rise 비
Rise Ratio of the 3 Continuous Spans Half Through Steel Arch Bridges Considering Wind Resistant Dynamic Stability
초록
The most important element is a rise ratio when regarding beauty and economics of arch bridges. Only the effect of dead load has been considered to decide the rise ratio. In this study, when going over the rise ratio of arch bridges, examined the problems, that the determination of the rise ratio by the dead load has, by adding the factor of a determination of optimum rise ratio, which is not only the effect of the dead load that has been currently considered but also the problem with respect to wind resistant dynamic stability that is now taken seriously. Synthetically, when deciding rise ratio that is investigated in basic step of design, it is not necessary to consider the evaluation wind resistant dynamic stability.
