Analyze the given structure that consists of the beam A-B and the truss element B-C by using the direct stiffness method for the degrees of freedom indicated below. The beam A-B is axially rigid. a) Form the structural stiffness matrix [K] and the load vector {Q}. b) Calculate the unknown displacements [D], c) Draw the internal force diagrams. EI = 2x104 kNm2 for A-B Truss element EA = 12x104 kN for B-C 4 m EA Y Beam A EI B 50 kN Degrees of freedom 6 m Analyze the given structure that consists of the beam A-B and the truss element B-C by using the direct stiffness method for the degrees of freedom indicated below.
