The article covers the experimental research into corrugated web beams exposed to the concentrated static load that has varied values of the width of load exposure. The authors describe the methodology of the experiment, instruments and machines involved in it, as well as the findings of the tests.Six beams with sinusoidal webs were selected for testing purposes. The beams were 6, 9 and 12 m long, and their cross sections were 500, 750 and 1,250 mm long. All beams were tested as single-span simply supported structures with hinged rigidly or loosely fixed supports.Beam tests have demonstrated that any failure to adhere to the beam manufacturing technology may seriously affect the load-bearing capacity of a beam. Any deviation of longitudinal axis flanges of beams from the longitudinal axis of a corrugated web in excess of 3 mm adversely affects the bearing capacity of beams and contributes to the overall beam stability loss.The research findings have demonstrated that the limit state of tested beams arises due to the stress in the web corrugation.

The authors cover the problems of the numerical analysis of corrugated web beams exposed
to constrained torsion. The calculation is performed using the finite element method. Virtual solid
models and software package "Lira" are employed to perform the structural analysis. The results
of the comparative analysis of performance of beams that have flat and corrugated webs and that
are exposed to constrained torsion are presented in the article. Corrugated web beams that have
different geometrical shapes of corrugations are considered.
The results of the research have proven that a beam that has a corrugated web demonstrates
average deflections of 15-18 %. The rotation angle of the midsection of a corrugated web beam
is by far below the one of similar beams that have a flat web. Comparison of beams that have different
corrugation web patterns and that are exposed to constrained torsion proves that beams that
have a corrugated triangular shape web have a better bending stiffness, while beams that have
a trapezoidal shape demonstrate the best torsion stiffness, given that the geometric parameters
remain the same.
The authors believe that the flexural stiffness of beams with a corrugated web needs more
research, depending on its geometric characteristics. These results can be taken as the basis for
the empirical and analytical dependence on the definition of deflection. Due to the fact that beams
with a corrugated web are less sensitive to the increase in the eccentricity of load, it makes sense to
apply the method of calculation of a flat web beam exposed to constrained torsion, but the qualifying
factor is to be applied.
