✨ Pitch of Roof Truss ✨
👉 It is the Ratio of Rise and Span is called Pitch.
👉 Pitch = Rise/Span.
👉 Normally the value of Pitch is kept 1/3 to 1/5.
👉 Lower pitches are more advantageous because the effect of wind pressure on the roof truss gets reduced.

✨✨Splicing in Tension Member ✨✨
If a single piece of a tension member is not available for the required length then tension members are spliced to transfer the required tension from one piece to another.
The strength of the splice plates and bolts/welded connections must have strength at least equal to the design load.
In case, connecting tension members are of different thickness, then filler plates are used.
As per IS 800:2007, the design shear strength of bolts carrying shear through a packing plate of thickness in excess of 6 mm shall be reduced by a factor given by,
βpkg = 1 - 0.0125 tpkg
tpkg = Thickness of thicker packing plate (in mm)

✨✨ Different Types of Buckling ✨✨
Bonus : Local Buckling occurs when a part of compression member shows lateral deformation instead of complete member.
