Influence Line Of Beam [ Structure Analysis 3 ]

Influence Lines An influence line is a diagram showing the variation of a particular force (i.e., reaction, shear, bending moment at a section, and stress at a point or other direct function) due to a unit load moving across the structure. Influence Line can be defined to be a curve the ordinate of which at any point equals the value of some particular function due to a unit load (say 1-lb load) acting at that point, and is constructed by plotting directly under the point where the unit load is placed an ordinate the height of which represents the value of the particular function being studied when the load is in that position. Influence Lines are often useful in studying the effect of a system of moving loads across a structure.
