洪水時に道路トラス橋梁に作用する流体力に関する研究

抄録

Bridges in upstream reaches of rivers have collapsed during floods in Japan. The authors investigated the field conditions of the collapsed truss bridges on the Mimi river and examined the causes of collapse of supports for girders of truss bridges by hydraulic model experiments. Fluid dynamic force exerted on girders of truss bridges is clarified.
