【 摘 要 】

The network arch is an economical bridge type that can look good and needs 35 to 50 % less steel. Economical methods of erection using light steel skeletons can be found. The network arch is defined by having hangers that cross each other at least twice [1]. The arches are made of steel. When the distance between the arches is less than 20m, the author thinks that the tie should normally be made of concrete.
