Question

Draw BMD and SFD for an overhang beam ABC with span BC overhanging. The
loading and span data is as follows
Span AB = 6 m; Full Span UDL = 20 kN/m,
Span BC = 2 m; Full Span UDL = 30 kN/m
Span BC = 6 m; Point Load at C = 15 kN.

Answer 1

=-(15x8)+(-30x2)(7))+R_Bx6-(20x6)x3)

 =-120-420+6R_B-360

 0=6R_B-900 

900=6R_B  

R_B=150  

R_A=45  

Bending moments 

BM_c=0 

BM_b=-30-60=-90

BM_A= -15x8-(6x70)+(150x6)-(120x3) 

=0
