Use the stiffness method to analyse the elastic frame ABC shown below. Use a model made up of 2 the elements (AB and CB) and the axis indicated in the figure. All members have the following properties: E = 2-108 kPa, A=0.005 m², I = 1.5e-4m².. Also the lengths of the elements are the same: AB = BC = L = 2.7 m and w=49 kN/m. A 00 I Structure, loading. member axes B I Calculate the the bending moment at Joint A, following the steps below: Part 1: Assemble the global structure stiffness matrix. Calculate: a) K11 b) K 22 c) K 33 kN kNm kN Part 2: Specify the load vector. Provide your answers with two decimal places. P = Degrees of freedom AN 3 Part 3: Calculate the displacements. Provide your answers with three significant figures: (For example, if your answer is 0.00001236 then insert 1.24e-5) a) U1 b) ₂ = c) uz = m rad m Part 4: Finally, calculate the absolute value of the moment at joint A Provide your answer with two decimal places. MA KNm Use the stiffness method to analyze the elastic frame ABC shown below. Use a model made up of 2 elements (AB and CB) and the axis indicated in the figure. All members have the following properties: E=2*10^8 kPa, A= 0.005m2, 1 = 1.5e-4 m4 Also, the lengths of the elements are the same: AB-BC=L = 2.7 mm and w= 49 kN/m Use the stiffness method to analyse the elastic frame ABC shown below.
