Muller-Breslau Principal The influence line for any stress function may be obtained by removingt function and introducing a directly related generalised unit displacemeht at the location and in the direction of the fucntion int offered by that INFLUENCE LINE FOR REACTIO To obtain influence line diagram of reaction at A, a unit displacement is given in the direction of R and other restraint kept intact. The ILD for shear at C is as shown below ILD or RA at To draw influencnf hear at C, release only shear and give unit displacement at C such that the two parta are separated by unity. The ILD for s庞ar at C is as shown below C,

Mc Mc or Mc Muller-Breslau principal provides a quick method for establishing the shape of influence line. Once this is known, the ordinates at thetpeaks can be determined by using usual methods . . We know that ILD for statically seterminate beam is composed of straight line segments. hence while using Muller-Breslau principl to draw ILD, if a segment of beam cannot have rigid body movement due to introduction of moment/hear reaction release and subsequent movement ILD for that segment will not exist. . In otherwords, in a statically determinate structure, if a segment of beam, on movement, has a propensity to attain eured shape, ILD will not exist for that segment
