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 El constant for the whole frame. Please use the gradual solution below and release My as the redundant moment. Take a = 14 KN and L. = 1.8 m D E B C im 3m b) Mb= -8.42 Your last answer was interpreted -2 m He -2 m Part 1) Draw the bending moment diagram of the primary structure and calculate the bending moment at A, D and H. a) M = 0 c) M}=-14 KN m Your last answer was interpreted b) mD= -0.598 kN m Your last answer was interpreted c) = 0 kN m Your last answer was interpreted kN m G Your last answer was interpreted 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) mд= 1 kN m Your last answer was interpreted kN m Part 3) Calculate the real bending moment at D MD= kN m follows: 0 follows: -8.42 follows: -14 H follows: 1 follows: -0.598 follows: 0
