Abstract

Reinforced concrete shear walls connected by coupling beams form an efficient structural system to resist earthquake and wind loads in tall buildings. However, the analysis of the effects caused by cyclic loading in this kind of system are not so straightforward. In the present paper, simplified nonlinear analysis using monotonic loading are used in order to obtain the behavior of tested coupling beams subjected to cyclic loading. Numerical results have shown that numerical monotonic loading is able to predict with good precision the yielding and the failure loads of the tested coupling beams subjected to cyclic loading. Both the cracking patterns and the predicted failure modes also followed the experimental behavior, ensuring that monotonic loading may be applied to have a first insight concerning cyclic loading.

Rafael Alves de Souza has received his Bachelor of Science in Civil Engineering from Universidade Estadual de Maringá (Brazil), Master of Science in Civil Engineering from Universidade de Campinas (Brazil) and Doctor of Philosophy in Civil Engineering from Universidade de São Paulo (Brazil) with a sandwich research conducted at Universidade do Porto (Portugal). He has also attended post-doctoral activities at University of Illinois at Urbana-Champaign and short research projects at École Polytechnique Fédérale de Lausanne (Switzerland) and TU Delft (Nederlands). His research focuses on reinforced and prestressed concrete structures, strut-and-tie models, nonlinear analysis using finite element method and forensic engineering. He is member of ABECE (Associação Brasileira de Engenharia e Consultoria Estrutural), IBRACON (Brazilian Concrete Institute) and ACI (American Concrete Institute), serving as magazine reviewer for both institutions. In 2006, he received from IBRACON an Honor Mention by his thesis about strut-and-tie models. He was the co-head of Civil Engineering Department at University of Maringá and his research activities are supported by CNPq (Conselho Nacional de Desenvolvimento Científico e Tecnológico). Nowadays he is Full Professor at the Universidade Estadual de Maringá and owner of Engracon Structural Engineering and Architecture (http://www.engracon.com.br).
