simplified method to work out reinforcement in concrete beam (Australian Standard)
(OP)
Hi guys:
The equations that I used at the moment is
0.85f'cbγkud=Astfsy and
M*=0.8*Astfsy(d=γkud/2)
I substituted the first equation into the second equation to form a quadratic equation in order to find the ku value.
After solving the equation i ended up with two ku values both below 0.4
I am a bit confused which ku value I should use to design the reinforcement
Is there any simplified method to work out steel reinforcement in concrete beam?
Regards
