According to the Müller-Breslau Principle, to construct an Influence Line Diagram (ILD) for a reaction or internal force, the structure is modified to show the deflected shape under the respective influence.
- When constructing the ILD for a vertical reaction at a pin joint, the Müller-Breslau Principle dictates that the pin support should be replaced by a roller guide
- This roller guide will allow the support to move freely in the horizontal direction while still resisting vertical forces, which helps in visualizing how vertical reactions change as a load moves across the structure.
This transformation models the system’s behavior under varying loads and accurately reflects the influence on the vertical reaction at the pin joint.
