Size Effect of Compressed Concrete in the Ultimate Limit States of RC Elements

摘要

In order to evaluate the limit state interaction curves of RC elements in bending and compression a numerical model is proposed. This approach shows some differences from the Eurocode 2, where the size effect on the structural response of compressed concrete is not taken into account. By varying the dimensions of RC members, the proposed model provides different stress distributions in compressed concrete and, consequently, more than one interaction m-n curves.
