Question
Determine the stiffness matrix of the frame as shown in Fig. 4. Nodes 1 and 3 are
fixed supports. Assume I = 300(10^6) mm4, A = 10(10^3) mm2, E = 200 GPa for each
member. Indicate the degrees-of freedom in all the stiffness matrices. Use the values
of L3=2.5m, L4=4.5m, w=12kN/m and P=10kN.
Please show all working and explain how the code numbers for global matrix are determined in detail.
