For the first time, questions of optimization of geometric parameters of developed I-beam with a perforated web are considered with the use of the finite element method in PC ANSYS Mechanical. For the linear model of the material, strength and stiffness calculations are performed depending on the shape of the cut: the height of the I-beam development and the distance between the holes. For the I-beam with the highest height, the stability of the web was checked, the first two critical loads and forms of stability loss were obtained. The optimum degree of development is shown on the example of the 12-meter developed I-beam from the initial rolled I-beam with a height of 60 cm. The strength and rigidity of the beam is determined when the length of the distance between the holes is changed.
