Question

A three span continouous beam of equal span 5 m each ,support udl of dead and live loads of 20 and 10 kn/m .Evaluate m1,m2 and m3 to elastic analysis with total load acting on all three spans

Answer 1

Notation

FBD = free body diagram

SFD = shear force diagram

BMD = bending moment diagram

E = modulus of elasticity, psi or MPa

I = second moment of area, in4 or m4

L = span length under consideration, in or m

M = maximum bending moment, lbf.in or kNm

R = reaction load at bearing point, lbf or kN

V = maximum shear force, lbf or kN

w = load per unit length, lbf/in or
