Abstract

enThe purposes of this thesis are the design, the numerical modeling and the experimental validation of ductile walls aimed to withstand seismic forces in a 4-storey reinforced concrete structure. Two types of walls are studied : the first is a classic reinforced concrete wall, while the second contains shape-memory alloy rebars (Nitinol) at its base. In order to conduct a quasi-static cyclic test campaign on those two walls, special attention is paid to the scaling of the structure and to the elaboration of an appropriate test protocol. A first non-exhaustive comparison between the experimental results and the numerical predictions of the reinforced concrete wall is then presented. This experimental research is complementary to the thesis entitled "Conception d’un dispositif expérimental pour des essais cycliques d’unités à grande échelle au LEMSC", written by Martin Steinmetz and Thomas Wyckmans. Its purpose is to provide the UCLouvain’s LEMSC with a device for testing and analyzing the response of structural elements similar to those described in this work.
