Abstract
A girder bridge structure with a tall and narrow central-wall-beam that separates two lanes of opposite traffic, lower parapets on each side of the bridge, open bridge decks with optional heated strips, self-driving reference guides, and electric live rails for maximizing the structural efficiency of the strength-mass and stiffness-mass ratios with the tall and narrow central-wall-beam; making the girder bridge lighter; increasing wind-resistance; providing a safer ride to vehicles; lowering the deck height of the bridge; providing reliable self-driving; reducing interference to traffic at ground level; reducing maintenance; improving the aesthetic look of the structure.
Claims20
A bridge girder between two piers for transporting vehicles with a first and second wheel-path, comprising:
- a central-beam that is located at the median of the bridge;
- wherein the central-beam has a height that is higher than or comparable to the vehicles;
- wherein the central-beam is narrow in width;
- wherein the central-beam serves to suspend and support most of the weight and load of the bridge and transfers their forces down to the piers;
- a first road deck that is located on one side of the central-beam;
- wherein the first deck contains a first lane for a first direction of the vehicle traffic;
- wherein the first lane contains a first and second runway;
- wherein the first runway is located under the vehicle's first wheel-path and the second runway under the second wheel-path.
A method of building a girder bridge between two piers for transporting vehicles with a first and second wheel-path, comprising:
- providing a central-beam that is located at the median of the bridge;
- wherein the central-beam has a height that is higher than or comparable to the vehicles;
- wherein the central-beam is narrow in width;
- wherein the central-beam serves to suspend and support most of the weight and load of the bridge structure and transfers their forces down to the piers;
- providing a first road deck on the bridge that is located on one side of the central-beam and a second road deck on the bridge that is located on the other side of the central-beam;
- wherein the first deck contains a first lane;
- wherein the first lane contains a first and second runway;
- wherein the second deck contains a second lane;
- wherein the second lane contains a third and fourth runway;
- wherein the first and third runways are located under the first wheel-path of the vehicle and the second and fourth runways are under the second wheel-path;
- pre-casting a plurality of original girder segments at an off-site location;
- wherein the girder segment contains a portion of said central-beam and decks;
- creating a group of great girder segments;
- wherein the great girder segment joins two or more said original girder segments according to the needs;
- using the original girder segments and great girder segments to build the girder bridge following a girder bridge installation process.
