This thesis studies the differences in the required amount of reinforcement in concrete structures since the introduction of the Eurocodes as the new standard for construction design in Sweden. The introduction of the European construction standards, the Eurocodes, as the new norm for design of structural elements in buildings on the Swedish market in 2011, put an end to the old Swedish standards set by BKR, boverkets konstruktionsregler. This thesis is based on comparison studies to analyze the amount of required reinforcement for crack width control in concrete cross-sections exposed to shrinkage strain according to Eurocode 2 and BBK 04. The study also deals with the influence of required reinforcement in the calculation of crack widths due to tensile stresses. The results in this thesis is built on comparative studies between the new Eurocode standard and the old BBK to examine and highlight the key differences when performing these types of calculations. The prerequisites for the calculations have been varied to obtain a clearer view of the outcome. The results show a general increase in the required amount of reinforcement when calculating according to Eurocode compared to BBK. It also shows that a higher total amount of reinforcement in combination with smaller dimensions reduces crack width.
