Fig. 5. Visualization of truss deflection under loading applied to the nodes of the lower chord at the ultimate limit state level. The diagram of the lower chord displacement along the Y-axis (deflection) along the length of the truss under the forces applied to the lower chord nodes is shown in Fig. 6.
