Abstract:
When designing structures to Serviceability Limit State it is essential to prove the cracks are within the ultimate values. Cracks do not always hinder a structure if their widths do not exceed the prescribed limit values usually conditioned by corrosion, impermeability to liquids or gasses, or by appearance of the structure. Procedures given in various codes such as [ENV 1992-1-1:dec. 1991], [BS EN1992-1-1:2004] as well as [DIN 1045-1]), for determination of crack widths and only for members subject to pure bending are considered in this paper work. Calculation of crack width in RC member is presented through examples and for short term (t = 0) and long term (t = ∞) loading, according to ENV 1992-1-1 and BS EN 1992-1-1:2004, while limiting of crack width without direct calculations is done based on the provisions within ENV 1992-1-1:2004, BS EN 1992-1-1:2004 and DIN 1045-1.
