The study refers to a new type of composite steel and concrete modified beams proposed by the authors. An engineering method for calculating composite steel and concrete modified beams taking into account real diagrams of steel and concrete deformations has been developed. For the proposed design of composite steel and concrete modified I-beams, a numerical study of the influence of the cross-sectional dimensions of the composite steel and concrete modified flange on the stress in the most compressed and maximally stretched fibers of the section of composite steel and concrete beams with perforated wall has been conducted. The analysis of the operation of modified beams of composite steel and concrete and the nature of their deformation using the finite element method has been performed. Numerical study of the stress-strain state was done according to the deformation model taking into account the physical nonlinearity of materials using different approaches to modeling the combined floor beam. The analysis of research results allowed to optimize the cross section of composite steel and concrete modified beams. [ABSTRACT FROM AUTHOR] |
