高力ボルト摩擦接合された２面添接形式鋼トラス橋格点部の力学的挙動とその有効幅算定法に関する２，３の考察

抄録

In this study, in order to clear the mechanical behavior of panel point of steel truss bridges using high strength bolted frictional joints, tensile loading experiment is carried out at first. Secondly, in order to make more detail clarification of the mechanical behavior and to examine the effective width of the gusset plate, finite element analysis has been executed by using the model which has same configuration of the specimen. From the results of this experiment and analysis, the collapse behavior of panel points of steel truss bridges is discussed and applicable evaluation methods of the load carrying capacity for yielding of such panel points are proposed.
