E is the modulus of elasticity of the beam, I represent the moment of inertia about the neutral axis, and M represents the bending moment at a distance x from the end of the beam. The product EI is called the flexural rigidity of the beam on deflections as well as stresses. Excessive deflection of a beam not only is visually disturbing but also may cause damage to other parts of the building. For this reason, building codes limit the maximum deflection of a beam to about 1/360 th of its spans. A number of analytical methods are available for determining the deflections of beams

We found that if we can find the deflection in the y direction of one point on the cross section, then we know the deflection of all points on the cross section. In other words, the deflection at a cross section is independent of the y and z. A number of practical reasons for studying beam deflections may be cited.

Deflection of Beams Introduction Because the design of beams is frequently governed by rigidity rather than strength. For example, building codes specify limits on deflections as well as stresses. Excessive deflection of a beam not only is visually disturbing but also may cause damage to other parts of the building. For this reason, building codes limit the maximum deflection of a beam to. Slope‐Deflection Equations • When a continuous beam or a frame is subjected to external loads, internal moments generally develop at the ends of its individual members.

When determining the deflection of a strut, the rule of thumb observed by the industry is that a deflection of 1/240th of the beam's span is acceptable The deflection of reinforced concrete beams is complicated by several factors. 1) The connections of a cast-in-place reinforced concrete frame usually transfer moment.
