Definition of Influence Lines
• We learned that shear and moment diagrams are important in determining the maximum internal force in a structure subjected to dead or fixed loads.
• If a structure is subjected to a live or moving load, the variation in shear and moment is best described using influence lines.
• An influence line represents the variation of a certain function (reaction, shear, moment, or deflection) in a member as a unit concentrated force moves over the member.
• Influence lines of determinate structures are made of straight lines.
