Reverse Arches (Hybrid CIty)


The reverse arches are compiled using Kerto LVL (as shown in the detail files) forming an array of mega arches that cover a span of 200m by 32m standing on only two supports and being balanced by tension cables. The weight of the arches is carried to the supports by three elements: the tension cables running through, an arched steel pipe and a circumference steel pipe

Key benefit

Covering a long span with only two spports forming a mega structure

Material list

Kerto LVL

Ecological values

The original structure is made entirely out of casted steel elements the replacement of the main beams with wooden ones can yield a positive effect on the environment especially when considering the wide span that the structure covers.
