Title: | Global behaviour of coupled unreinforced masonry reinforced concrete wall structures | Authors: | DEGEE, Herve FREDERICKX, Florian VANDOREN, Bram |
Issue Date: | 2018 | Source: | Milani G.; Taliercio A.; Garrity S. (Ed.). 10th IMC - proceedings of the 10th International Masonry Conference,p. 610-617 (Art N° S03 520) | Abstract: | This contribution deals with numerical investigations of hybrid unreinforced masonry- reinforced concrete wall structures (i.e. RC and URM walls coupled by reinforced concrete beams or slabs) used as horizontal stabilization systems. Although the combination of these materials is used as a bracing system in several countries, oversimplified design assumptions are often applied due to a lack of knowledge of the structural behavior of such systems. Therefore, this paper aims at improving this knowledge. The numerical campaign resorts to a pushover analysis: the focus is put on the lateral bracing resistance under statically increased horizontal loads. A finite element model developed, calibrated and validated in previous publications is used to perform a parametric analysis on global geometric parameters. A first set op case-studies consists in varying some global geometric parameters (length of the walls, distance between URM and RC wall, storey height, number of storeys) while a second set of case-studies deeper investigates the influence of the length of both walls. This constitutes a first step towards an optimization of the performances of such hybrid unreinforced masonry-reinforced concrete wall structures. | Keywords: | unreinforced masonry; reinforced concrete; coupling; in-plane stability | Document URI: | http://hdl.handle.net/1942/27997 | Category: | C1 | Type: | Proceedings Paper |
