Serviceability limit state analysis of a cracked cross-section in accordance with SRPS EN1992-1-1 and PBAB'87

Abstract

Serviceability limit state analysis is an important part of the design of reinforced concrete structures in order to meet the requirements of functionality, durability and aesthetics of the structure. The application of European standards (Eurocodes) in construction in the Republic of Serbia has started recently and there are still disagreements in the interpretation of certain provisions of the standards. On a simply supported reinforced concrete beam at an authoritative cracked cross-section was analyzed the applications of different combinations of permanent and variable actions for purpose of calculation characteristic crack width and deflections at the moment after inflicting load of a class S4 structure and at the end of service life. The results of the calculation according to Eurocode are compared with the results of the calculation according to the Standard for Concrete and Reinforced Concrete from 1987 for interpretation and selection of the relevant combination of actions.
