Steel Structure Design - Engineering

Q1:

The area Ap of cover plates in one flange of a built up beam, is given by

A

B

C

D

E none of these.

ANS:D -

Z required = M/bending stress.
Max. Bending stress = 0.66*250 = 165n/mm2.

Always z required <zavailable.
When bending moment increases existing zavailable then extra plate provided for covering to it.

Hence plate area calculate .
Zrequired-zavailable /h.
