EVOLUTION OF NORMATIVE APPROACH TO ANALYSIS OF REINFORCED CONCRETE STRUCTURAL ELEMENTS

Abstract

Strength analysis of cross-sections, stiffness and cracks width calculations, P-delta analysis of strucural members are reviewed within Russian Codes. Primary calculation tool of the modern Code is non-linear "deformation model". It is noted a saturation of normative approach by the empirical coefficients. Development of advanced models, decreasing a role of empirical component of reinforced concrete theory, is seemed to be one of the ways to Code improvement.
