THE SOFTWARE ENHANCEMENT FOR SIMPLIFIED STRENGTH COMPUTATION OF I-BEAM

Abstract

The article is devoted to the subsequent development of previously created end-to-end computer programs for simplified strength analysis of statically determinable double-support and cantilevered I-beams. The aim of this development is to give these programs the additional functions to determine linear and angular displacements in beams by using the Mohr method. To this end, analytical dependencies have been established to determine the values of bending moments in the beam sections from the action of single force factors - the force and moment applied at arbitrary points of these beams. Based on these dependencies, an additional computation for determining displacements were made that improved the capacity of the existing programs for calculating beam strengths. The modified programs calculate the Mohr integrals, thereby determining the desired displacements and plotting their changes along the length of the beams. These programs have been successfully tested in a series of calculations of beams of various types and demonstrated its efficiency and effectiveness. The introduction of the modified programs in the educational process will provide students with new opportunities in the formation of their professional skills. The indicated programs will be useful for professional practitioners as a fairly simple calculation tool for solving real technical problems.
