How Arch Footing Bearing Type Affects Internal Force on Arch Leaf |
| |
Abstract: | A study is given on one of the factor that affects the internal force on arch leaf in a steel-framed arch bridge. Under the theorem on displacement, we count and compare the internal force on arch leaf with different bearing, and draw a conclusion of the affect of each factor to internal force on arch leaf. |

Keywords: | framed arch bridge theorem on displacement bearing type internal force on arch leaf |
