Multi-layer construction elements improve technical characteristics of the product. There is exhaustive analysis of software in this work. Besides that the model for design of multi-layer construction elements subjected by bending is created in this work. The purpose of this program is calculation of stiffness and stresses for multi-layer constructions subjected by cross forces and bending moments. Modeling the design process of multi-layer construction elements is simple task that can be automatized by creation of modeling system. This program allows to calculate stiffness and strength of multi-layer construction elements subjected by cross forces and bending moments. It is possible to design various constructions of beams changing different parameters. The programme itself is simple for every student, engineer.This model can be used for scientific research, engineering calculations, laboratorial calculations. The program allows to evaluate strength of multi-layer construction element subjected by bending. The construction will not hold out external load if intensity of stresses in one layer exceeds permissible stresses of strength limit of this layer material. The report is given in such case. The distribution of calculated stresses in cross-section of multi-layer construction elements can be shown graphically. It significantly facilitate designer’s work.
