### Matlab Code for a Two-Dimensional Truss Bridge.

2次元トラスブリッジ用のMATLABコード。

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.

Figure 2: It shows the distortion (node displacement) when the force apply given by figure 1. Note that the displacement is exaggerated 100 times.
