Concept explainers

Influence Lines

The graphs that show the variation of a function at a specific point on a beam or truss due to a unit load placed at any point along the structure are known as influence lines in engineering. Some common functions that are studied with influence lines are shear, moment, and deflection. In designing beams and trusses, it is important to use influence lines in structures where loads would move along their span such as bridges, crane rails, conveyor belts, floor girders, etc. The influence lines help to study where a load will create the maximum effect for any of the functions.

Question

**Problem 8.41**

Draw the influence lines for the shear in panel DE and the bending moment at E of the girder with the floor system shown.

The figure depicts a horizontal girder divided into 7 equal panels, each measuring 18 feet, culminating in a total length of 126 feet. The girder is supported at several points:

- The supports are located under points B, C, D, and F.
- The panels between supports are as follows: AB, BC, CD, DE, EF, FG, GH.

To address the problem, influence lines for both shear in panel DE and the bending moment at point E need to be constructed. The influence line represents how the shear force and bending moment at a specific point in the structure change as a unit load moves across the length of the girder.
