PROBLEMS OF COMPUTER STRUCTURAL ANALYSIS AND REINFORCEMENT CALCULATION TECHNIQUES OF REINFORCED CONCRETE RIBBED SLABS

Abstract

This paper proposes an overview of computer structural analysis and reinforcement calcula
tion techniques of reinforced concrete ribbed slabs that are used in Ukraine. It considers the fundamen
tal hypotheses and assumptions of these techniques and analyzes the possibility of implementation of
the building codes' requirements into automated calculations. Numerical experiments confirm the exis
tence of a relationship between the normal stress distribution pattern in the rib's cross section and the
width of the slab zone, which participates in the rib's bending. We conclude the need to develop a gene
ralizing methodology of FEM structural analysis for such structures, which could be implemented in
modern FEManalysis packages implementing building information modelling technology (BIM).
