Abstract

The Model Code 1978 meant an important advance in the Limit State of Cracking assessment, reflected in the Instructions EH-88 and EH-91, which basically assembled this method. Later, with the purpose that different tests responded to just one approach, conveniently justified from a theorical point of view, an evolution developed, that at the moment, has become more definite in the design methods of characteristic crack width proposed in the Model Code CEB-FIP 1990 and EC-2.
