支承交換におけるジャッキアップ時の応答を踏まえた補剛材設計手法の考察

抄録

There is no specific calculation example for designing the required bolts to connect the jack-up bearing stiffener and the web plate of the main girder. Then, regarding the specifications for highway bridges, there is also a way of thinking that adopt twice the reaction force. This study constructed a finite element model for a simple steel girder bridge. And the shear force generated in the bolt was compared with the design value. From analytical results, the shear force was less than 50% of the design value, adopting twice the reaction force in analytical model. Therefore, it is show that the number of bolts can be reduced, and the efficiency of the maintenance work will improve.
