Week 5, Question 1: Using the force method, calculate the bending moment at D for this one-fold statically indeterminate frame. Ignore the axial and shear deformations and consider EI constant for the whole frame. Please use the gradual solution below and release M₁ as the redundant moment. Take a = 19 kN and L = 1.2 m. 3 m b) M₂ = c) M = b) mp c) mH B A 2 m- 0 D Your last answer was interpreted as follows: 0 kN m kN m E 2 m a Part 1) Draw the bending moment diagram of the primary structure and calculate the bending moment at A, D and H. a) M 0 kN m Your last answer was interpreted as follows: 1 kNom kN m F G 2 m Part 2) Draw the bending moment diagram of the redundant structure when applying a counter-clockwise unit moment at I. Calculate the bending moment at A, D and H. a) m₁ = 1 kN m H
Part 3) Calculate the real bending moment at D MD = kN m
