corrugated steel arch load carrying capacity
 

corrugated steel arch load carrying capacity?
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.
check out our whitepaper library.
try the following link. specifically chap. 7
exactly what i was looking for thanks sheperd
