From this drawing, what are the correct joist sizes for my flat roof.
Some facts;
Joist Span 4.8m
Gradient 1 in 80
Joist size 170 x 45 [Regularised Size / Finished Size]
Spacing @ 450 c.c
C24 SPAN TABLE
According to this span table
A Dead Load [kN/m2] below 0.25 can allow a span of 3.83m ,
So would this mean my joist sizes are under the specified standard?
What would be the Imposed Dead Load for a Flat roof?
Thank you.
