TRANSVERSE SHEAR DEFORMATIONS FOR DEFLECTIONS OF THIN-WALLED BEAMS

Iryna Ilchenko Nina Marchenko Borys Grynevytzkiy

The Euler-Bernoulli theory (classical theory) is mainly used when beam deflections are determined. Classical theory takes into account only pure bending while transverse shear deformations are neglected. The paper examines statically determined thin-walled beams (I-beam and thin circular ring): simply supported beams and cantilevers. The load is uniformly distributed along the length of the beam and cantilever and a concentrated force applied at the center of the simply supported beam and at the edge of the cantilever. For the specified cases, as well as for round and rectangular beams, formulas for the correction coefficient were derived. The coefficient takes into account the deformation of the transverse shear. It is shown at what relative length of the thin-wallde beams, the specified deflection exceeds the classical one by more than 5%
