Abstract: The article deals with the application of one of the experimental optical-geometric methods which is the method of moire strips with a reflected grid (according to the Ligtenberg scheme) to the study of I-beam corrugated beams with different wall configurations of constant thickness, rigidly fixed on one side and free on the other (console). The bending deformation process was observed from the action of a concentrated force at the free end with the gradual loading at different intervals of the applied force action. A model of a beam made of low-modulus material (plexiglass) with two types of wall profile: wavy and triangular was tested. The modeling process of the studied beams was developed. Virtual technique of moire patterns formation with the subsequent computer processing by standard programs was applied. The analysis of the deflections along the beam length depending on the load is given and deflections graphs are constructed in comparison with the theoretical calculation for models with corrugated and flat walls (standard I-beam).
