Corrugated Steel Arch load carrying capacity?
Corrugated Steel Arch load carrying capacity?
(OP)
Anyone know how to calculate the load carrying capacity of a corrugated steel arch thats been backfilled, want to replace a broken concrete culvert.
My structure first principles are a bit rusty.
The section properties:
Yield of a plate=250n/mm^2
Plate thickness,t=7mm
Area of Section=8.31mm^2/mm
Inertia,I= 3208mm^4/mm
Section modulus = 103.5mm^3/m
radius of gyration, r=19.65mm
Circle length=10.930m (Semi circle)
Radius=3.5m
corrugation=200mm long & 55mm high
Do i only check for axial stress straight through the plate or will a moment occur halfway.
