Q1:

In the formula a + bk for the calculation of the net effective section of single tee in tension connected by flange to the same side of the same side of the gusset, the value of 'k' is taken

A

B

C

D

ANS:C -

Given answer is right.

1- for single angle connected by one leg only ;
A= a+kb where k=3a/(3a+b) or say 1/{1+0.33(b/a)}.

2-for pair of angle connected by flange to same side of the gusset;
A = a+kb where k=5a/(5a+b) oer say 1/{1+0.5(b/a)}.
