Comparison of Punching Shear Design in Finland According to the Current and the Former Method

In the beginning of 2017 the design method for punching shear in Finland was changed. The method presented in Eurocode 2 was adopted with some nationally determined parameters and rules. During 2016 and 2017 computational analyses were conducted to compare the previous national design method and the new one. Comparison setups were created in which different parameters were varied. The results were presented as line charts. The focus was to find out how the predicted punching resistances differ between the two methods. It was discovered that the differences are significant and can be almost 60% in some cases.
