Question 6.8: People walking together in a group tend to walk side-by-side...

Structural Analysis: Skills for Practice

People walking together in a group tend to walk side-by-side. Therefore, they cause a point live load on a pedestrian bridge. For this bridge, the point live load on one truss is 6001b. In Example 6.4, we developed the influence line for the axial force in member BH. In order to calculate the peak tension and peak compression in member BH due to the point live load, let’s use the influence line.
