Matlab-Code für eine zweidimensionale Fachwerkbrücke.
For the two-dimensional pin-jointed truss bridge shown in Figure 1, the Young’s modulus is E = 200 GPa and the cross sectional area is A = 1500mm² for all truss members. The truss structure is subjected to a varying load F acting downwards in the nodes 6, 7, 8 as depicted in Figure 1.
Create a MatLab computer program to:
1. Compute the global displacements at all nodes, the reactions at the supports and the axial forces in every truss member for F = 20 kN.
Draw the undeformed shape (in blue) and the deformed shape (in red) of the bridge in the same graph. The results are displayed in Figure 2.
