The proposal can be sim-ply described as a truss where the typical quad-rangular or triangular grid has been altered in both the horizontal and vertical directions.
Such distortion is achieved through a geo-metrical algorithm where each variation is stored in a digital model to fa-cilitate later fabrica-tion.
Double-crossing truss with bays varying dimensions both in the vertical and horizon-tal directions. The truss members are circular section tubes.
Single span bridge with en-castrated supports at both ends. Boulders could be used to reinforce the abutments and to restraint the ends of the circular members.
Circular main truss mem-bers are made of bamboo rods treated and protect-ed against humidity and deterioration.
Boulders are used at the abutments to improve their stability and to re-straint the ends of the bamboo members at the en-castrated supports.
The walking platform is made of plywood and re-inforced longitudinally and transversely by bam-boo rods.
Each member is made of a bam-boo rod which has been cut to size and identified with a code to facilitate the as-sembly process.
Each bay can be assembled off-site and then transport-ed to site for final assembly and erection of the bridge.
The curvature of the bridge is achieved by varying the angle of orientation of each rod.
All the bamboo rods are straight. There is no need to bend them to achieve the geometry.
Erection on site might re-quire further investigation of the site conditions.
Materials used are consider-ably light and thus, erec-tion without heavy machinery should not present a prob-lem.
