Bending shearing-force diagrams

A beam subjected to a simple transverse load (Figure 2-29a) will bend. Furthermore, if the beam is cut (Figure 2-29b) and free body diagrams of the remaining sections are constructed, then a shear force V and a moment M must be applied to the cut ends to maintain static equilibrium.

For the constitutive modeling of inelastic FE macromodels under static seismic-type load, the multilinear (simplified or more refined) shear force-interstory drift or bending moment-pier rotation diagrams of Fig. 11 have been proposed... 

The diagrams, as in Figure 10.18, are characteristic for a test when specimens are loaded by one or two concentrated and symmetrical forces. These two cases are four-point or third-point with two symmetrical loads and three-point or centre-point with one force in the middle of the span. The first system is considered as better reflecting the bending conditions in the central part of the element, where pure bending without shearing is created. The second system is simpler to execute, but in fact the maximum effort is...
