ABOUT COMPUTER PROGRAMS FOR SIMPLIFIED METHODOLOGY OF COMPLEX ASSESSMENT OF STRENGTH OF TWO-BEAM BEAMS

Abstract

Computer programs for calculation the strength of statically determinable double-support and cantilevered I-beams are based on the previously proposed concept of using safe factor spaces of I-beams and significantly simplify and speed up the calculation process. The programs are created in the Mathcad system and illustrated by a numerous of examples. Programs use unified beam schemes, which geometric and power parameters are set by the user. All further calculation is performed by computer in automatic mode. The computer determines the beam support reactions, builds its specific calculation scheme, depicts the diagrams of the shear forces and bending moments, determines the minimum of I-beam size that satisfies the strength conditions for normal, tangential and equivalent stresses. The completed software developments can be recommended to the students and engineers to use for educational purposes and engineering practice. It is recommended to add more functionality to the programs - to determine the deformations of beams - deflections and angles of rotation of sections, which will significantly expand the range of the considered tasks.
