Question

Page 30 (18) 5.a) For the determinate, two-span beam shown, draw the influence "span beam shown, draw the influence lines for: i) bending moment at point B ii) shear force immediately right of point C, and iii) reaction at support C For each influence line, calculate and indicate the value of the influence coefficient that has the maximum absolute value. 15m 5m2m Bm

Answer 1

o for Bending moment. As per Muller, without removing the suppose at A&C assume an imaginary einge at B and apply unit rotation (to apply unit rotation, the linge must be lifted by an amout of OA+OB= 1

5X5 = 2157 OA= 08 = 2:5=0.5 TOA OBX92m A 5 B 5 COBly OB = y1=015 → you im © & A5 Per mulier without removing support at A cut the beam at R45 07 C , without removing moment at co give wit displacement L ① А в o As Per muller to draw ILD for reaction at Any Support remove that support & give mit displacement. Y,=112 41 to Y,=112
