The application is designed for calculations of straight, maximum three times static indefinite beams with constant axis-symmetrical profiles. Application is developed in MS Excel, is multi-language, supports Imperial and Metric units and solves the following main tasks: - Simple definition of the type of beam and its loading with visual check. - Calculation of area characteristics of 20 types of cross sections. - Calculation of reactions in supports. - Calculation of minimum / maximum bending moment, stress and deflection of the beam. - Calculation and graphic illustration of the moment, stress, deflection and bending angle of the loaded beam. The application includes a table of materials and a table of area characteristics of W, S, C, L profiles acc. to ANSI/AISC and I, U, L a T profiles acc. to DIN/ISO. Used standards: DIN 1025, 1026, 1028, 1029, 1024, AISC W, S, C, L, LUThis module is a part of MITCalc - Mechanical and Technical Calculation Package for gear, belt and chain drives, springs, beam, shaft, bolt connection, shaft connection, tolerances and many others
