TLDR
In this article, a matrix formulation is used to estimate the maximum deflection of composite beams with web openings and an expression for calculating the deflection across a web opening is given.Abstract:
Procedures for calculating the deflections of composite beams with web openings are described. Initially, a matrix formulation is used. Modeling assumptions are verified by comparison with experimental data, and recommendations for practical application of the matrix analysis procedures are made. The results of the comparison are used to develop a design aid for estimating the maximum deflection of beams with web openings and an expression for calculating the deflection across a web opening. The work demonstrates that, in most cases, a single web opening often has little effect on the total deflection of a composite beam. There are, however, important cases where the effect can be significant. The effects of an opening and of shear deflections are of the same order. Ignoring both the web opening and shear deformation can lead to significant error. The matrix stiffness method, the design aid, and closed form equations provide reasonable estimates of both total deflection and deflection across an opening.read more

Inclusion of shear deflection in the stiffness matrix for a beam element
TL;DR: In this article, the stiffness matrix is obtained on the basis of stress assumption, rather than the more usual displacement assumption, and an erroneous addition of the shear-deflection terms to the bending terms can be made if an apparently straightforward approach is utilized.

Elastic Deformation of Beams with Web Opening
TL;DR: In this article, a theory for determining the elastic deformations of beams containing concentric or eccentric rectangular web openings is presented, which combines the primary deflection (determined as for an unperforated beam) and the deflection due to Vierendeel action at the web opening.
