After designing a beam. The following checks are necessary

1. Minimum Reinforcement Area which ranges between 0.13bh -0.24bh

2. Maximum Reinforcement Area which ranges from 4bh to 6bh

3. Deflection Check which involves comparing the actual length/depth ratio to the allowable length/depth ratio

4. Cracking that deals with clear bar spacing, maximum aggregate size and reinforcement size.

5 Shear stress: This deals with shear force and section area. It ranges between 0.8√Fcu and 5N/mm^2

Most times good people always complain, about how people take their goodness for granted.

If people always take your goodness for granted.
Then this post is for you

The truth be told goodness requires alot of smartness which includes

Stay away from people with entitlement mentality. You can hardly satisfy people with such mentality and they hardly appreciate goodness because they feel and believe that they are doing you a favor for receiving your goodness

Stay away from parasitic people. Parasitic people purposefully comes into your life with the mindset of just taking from you and they have no intentions to add anything valuable to you. They are usually greedy and stingy and are always ready to drain you off all you goodness

Finally purposefully make friends with likeminds, become friends with people that illuminates goodness, befriend people that appreciate every little fraction of your goodness.

Beams are horizontal structural members that withstand vertical loads, shear forces, bending and torsional moments.

We have Concrete Beams, Steel Beams, Timber Beams and Composite Beams.

The depth and width of a beam can be determined from length/depth ratios, maximum shear force, maximum bending moments and exposure conditions.

The maximum support moment is 0.11FL
The maximum span moment is 0.09FL
The maximum Shear force is 0.6F
Where
F= Total Design Ultimate Load
L= Effective Span
As in table 3.5 BS 8110-1:1997

Provided the beam is a uniformly loaded continuous beams with approximately equal spans
