Investigation of the reliability of the Eurocode 2 model for early age cracking of liquid retaining structures in South Africa
Abstract eng: Liquid retaining structures in South Africa have traditionally been designed using design code BS 8007 (now superseded by EN 1922-1-1(2004) & EN 1992-3(2006)), due to South Africa having not yet developed its own code for the design of liquid retaining structures. In adopting the Eurocode in the South African environment, its reliability performance against local reliability requirements must be assessed. The dominant design criterion for liquid retaining structures is cracking—a serviceability limit state. Thus a study into the reliability performance of the EN 1992 crack model as applied to the South African context was conducted using the First Order Reliability Method (FORM) of analysis. Cracking from restrained deformation was the focus of this paper. The influence of concrete cover, reinforcing steel diameter to effective steel content ratio, section thickness; restraint factor and model uncertainty on the reliability of the edge and end restraint crack models were investigated.
