BRIDGE FOOTING AND MANUFACTURING METHOD THEREOF
To provide a bridge footing with improved earthquake resistance and a manufacturing method thereof.SOLUTION: A bridge footing 2 comprises: an outside plate 4 that has box-shaped cross-section; and multiple ribs 6 that are disposed on each internal wall surface of the outside plate 4 so as to extend in a longer direction of the outside plate 4. Steel materials of the same standard (in accordance with specifications for highway bridges) are used for the outside plate 4 and the rib 6. A value of YR of the steel material used for the outside plate 4 is smaller than that of the steel material used for the rib 6.SELECTED DRAWING: Figure 1
【課題】耐震性を向上させた橋脚およびその製造方法を提供する。【解決手段】箱型断面を有する外板４と、外板４の内壁面のそれぞれに外板４の長手方向に延びるように複数設けられたリブ６とを備える橋脚２およびその製造方法であって、外板４とリブ６に同一規格（道路橋示方書に準拠）の鋼材を用いるとともに、外板４の鋼材の方がリブ６の鋼材よりもＹＲの値が小さいものを用いた。【選択図】図１
