MOMENT -AREA METHOD
Presented ByAbhishek KumarB.Tech,4th Sem.(Session-2011-12)Dept. Of CIVIL EngineeringMewar University
What is moment area method?
This is one of the easiest methods for finding deflection and slope of a beam with the
help of area of bending moment of the beam, which is loaded with some load or any
moment at any point or on whole span.
PROOF
------------(1)
For finding slope
For deflection
Now We get
Where M.ds=area of b.m. diagram
M.x.ds=moment of area of b.m. diagram
Theorem 1
Theorem 2
These theorem is also known as Mohr’s theorem.
