Consider the following truss bridge which is constructed from pin-connected round steel bars of diameter d = 50 mm, Young's modulus E = 200 GPa and Poisson's ratio v= 0.30. The bridge is loaded by two concentrated forces, as shown in the figure below. Develop a finite element model in ABAQUS in which each bar is modelled by one linear truss element. Perform the analysis and complete the following tasks: (a) Show a figure of the undeformed truss bridge including node numbers. [5 points] (b) List the deformations at all nodes. [5 points] (c) Determine the reaction forces at the supports. [5 points] (d) Provide a contour plot showing the axial stresses on the deformed truss bridge. [3 points] (e) Identify the truss elements with the highest compressive and tensile axial stress, respectively.
