Influence of Boundary Conditions on the Behavior of Infilled Frames

This paper focuses on the influence of the contact surfaces between autoclaved aerated concrete blocks (AAC) and the surrounding reinforced concrete frame. From the experimental results and from the model proposed by the authors, different behaviors between ideal and real models have been analyzed and compared given a variety of aspects: the stiffness degradation, the drift, the cracking peak, the strength, the ductility and the energy dissipation. The research aims to provide parameters for calculating work approaching the actual behavior to obtain safer and cost-saving construction.
