,Structural Analysis

QUESTION 1: MOMENT DISTRIBUTION METHOD

 Fixed support at A
 Pinned support at F
 25 kN point load at B
 40 kN point load at D
 UDL of 10 kN/m on EF

Step 1: ASSUMED MEMBER LENGTHS


Member Length (m)

AB 4

BC 3

CD 3

DE 4

EF 3



Step 2: FIXED-END MOMENTS (FEM)

For AB: 25kN point load at midspan




For BC: No external load = FEM = 0

, For CD: 40kN point load at midspan




For DE: No load = FEM = 0

For EF: UDL of 10kN/m over 3m




Step 3: STIFFNESS FACTORS (Assuming EI = constant)
