Q4. Statically determinate or indeterminate frame analysis by the stiffness method a) Determine the stiffness matrix of the frame as shown in Fig. 4. Nodes 1 and 3 are fixed supports. Assume I = 300(10%) mm, A = 10(103) mm², E = 200 GPa for each member. Indicate the degrees-of freedom in all the stiffness matrices. Use the values of L3-3.5 m, w = 24 kN/m and P = 30 kN. Note, L4-1.8L3 (i.e. 1.8 times L3). b) Determine all the displacement components at node 2 and all internal reactions at node 2. Show all calculations. c) Draw the BMD of the frame on the compression side showing all the salient values. Show all calculations. d) Repeat the problem using the Strand 7. Show the model with all the nodes and element numbers and boundary conditions. Submit a hard copy from Strand7 showing all the reactions (highlight these in the hard copy). Display the bending moment diagram for the frame. 4 e) Compare the BMD from Strand 7 with the theoretical one and compare the respective values of…
Can you please break down all the hand calcs and make sure we answer the below.   a Determine the global stiffness matrices (k’) of all truss members including correct degrees-of freedom (dof)-3x3 b Determine the global stiffness matrix (K) of the whole truss (include dof numbers) c i) Calculate vectors D and Q (4+4).    ii) Show partition and solve KD=Q        iii) Calculate all the member forces         d i) Solve the problem using Strand7 (model) (You must model the beam property as truss)   ii) Display of deflected shape, nodal displacements and member forces (3+3+3)  e Comparison of member forces and comments , comparison of displacemnts and commnets
