I heard Thump rule about beam depth is 1" per 1' length. Is
this correct? If not please tell me the thump rule.Thanks.

Answer Posted / amreeta

no it is to calculated like
100mm depth per 1m span ..when the total depth(D) is not
given.
after you get the total depth(D)
then calculate effective depth(d)
d = D-(cover of the beam +radii of the rod)

assume cover = 20-25mm
dia of the rod 16-20mm
