Safety Evaluation of EC2 and MC 2010 Models for Assessment of Punching Resistance of Footings

Abstract:

Article Preview

Model for assessment of punching resistance in Eurocode 2 has been taken over from Model Code 1990. The model is fully empirical and was developed in 70s based on the experimental results obtained on flat slab specimens mainly loaded under axis-symmetric conditions. Therefore some doubts are soaring about applicability of the model for assessment of slab members exposed to the different conditions. Spread footings and foundation slabs represent such members. Growing number of experiments carried out on the footings last two decades allowed us to check safety of current model and compare it with the safety of the new models e.g. mechanical model based on the Critical Shear Crack Theory (CSCT) published in Model Code 2010 or amendments of EC2 model proposed by German group.
