Design of concrete structures according to Eurocode 2 and BAB 87: comparison of basic calculations

Abstract

Structural Eurocodes have superseded national design codes in a number of countries. The education of engineers is necessary for quick and successful adaptation to new standards. Qualified institutions should organize appropriate training programs and provide quality manuals with clear and precise instructions. A possible approach for practicing the new regulations is to compare the procedures and results of the design according to the former regulations, which are well known by the designers, and the corresponding procedures in the new regulations. This paper compares the basic design inputs in the Code for Concrete Structures of the Former Yugoslavia (BAB 87) and Eurocode 2 (EN 1992-1-1: 2004). In addition, a comparison of the basic ULS and SLS design procedures is presented, as well as an analysis of the obtained results. ULS design for bending and for shear are studied. Control of cracking and deflection control are covered in the SLS domain. The comparisons are intended to indicate to the designers whether their previous experience in the design of structures is in accordance with the requirements of the new regulations. The derived conclusions can be useful in assessing the compliance of existing structures, designed according to BAB 87, with the requirements of Eurocode 2
