The Timoshenko–Ehrenfest beam theory was developed by Stephen Timoshenko and Paul Ehrenfest early in the 20th century. The model takes into account shear deformation and rotational bending effects, making it suitable for describing the behaviour of thick beams, sandwich composite beams, or beams subject to high-frequency excitation when the wavelength approaches the thickness of the beam

Timoshenko beam theory [Timoshenko 1921; 1922], also sometimes referred to as a ﬁrst-order shear deformation theory because it allows for nonzero transverse shear strain, is represented by two unknown functions that represent the transverse displacement (w) and the total section rotation (9) of the beam cross-section Tall building was modeled as a cantilever beam and analyzed with the assumption of flexural behavior based on Euler–Bernoulli Beam Theory, then the displacement of floors was calculated. o consider the shear lag effects in the overall displacement of the structure, Timoshenko’s beam model has been considered and related relations were extracted.
