The Tee-Beam Effect of Roof Sheeting

Tests were carried out to deterrmne if roof sheeting acted in conjunction with a rafter to form a tee-beam effect. The results showed that the stress m the sheeting was far less than would be reached in a true compound sectlon and appeared to depend more on the number of fastening bolts than on the actual width of sheeting used. Although the moment contribution of the sheeting in the experimental tee-beam was as great as 25 per cent of the applied moment, it 1s shown that in a real design the effect would be negligible. E.R.
