“…The SRB-DUP structure proposed is shown in Figure 3 (Yamaguchi et al, 2005b). It is a new type of drymasonry structure where solid elements, such as bricks, and horizontal reinforcing elements, such as steel plate, are laid alternately and fixed at each level with vertical reinforcing elements, such as bolts, and utilizing a friction-resistant stress-transfer mechanism.…”

A new structural type is proposed and tested: steel-reinforced brick based on distributed unbond prestress theory (SRB-DUP). This is a dry-masonry structure with a friction-resistant stress-transfer mechanism. The elements comprising the entire assembly are not bonded to each other, allowing deconstruction for their easy reuse or recycling. Laboratory tests are reported on the structural performance of walls, beams and columns. Horizontal loading tests of walls and bending tests of beams along their strong axes reveal that the energy-absorbing capacities of both are high. Bending tests on walls and columns along their weak axis showed that both have high elastic deformation capacity. The SRB-DUP structure is a newly proposed type of earthquake resilient construction, different from other structural systems such as earthquake resistant construction, vibration control construction, and construction of vibration isolation. After meeting strict Japanese structural standards, the construction of two experimental houses using SRB-DUP structures was authorized. A new type of brick, with a uniform height achieved by covering it with fly-ash slurry mortar, has also been developed.Cet article présente un nouveau type de structure ainsi que les essais auxquels il a été soumis: il s'agit d'une brique renforcée à l'acier conçue selon la théorie du précontraint non collé distribué (SRB-DUP). C'est une structure en maçonnerie sèche avec un mécanisme de transfert des contraintes résistant au frottement. Les éléments qui composent l'ensemble ne sont pas collés les uns aux autres, ce qui permet et facilite leur déconstruction et leur réutilisation ou leur recyclage. L'article rend compte de tests menés en laboratoire sur les performances structurales de murs, de poutres et de colonnes. Des tests de charge horizontale menés sur des murs et des tests de flexion menés sur des poutres le long de leur axe fort révèlent que les capacités d'absorption d'énergie sont élevées dans les deux cas. Les tests de flexion sur des murs et des colonnes le long de leur axe faible montrent que dans les deux cas, la capacité de déformation élastique est élevée. La structure SRB-DUP est un nouveau type proposé de construction dont la résilience permet de résister aux séismes et qui est différent des autres systèmes structuraux comme les constructions antisismiques, les constructions antivibratoires et la construction d'amortisseurs de vibrations. Conforme à des normes structurales strictes japonaises, la construction de deux maisons expérimentales utilisant des structures SRB-DUP a été autorisée. Un nouveau type de brique, avec une hauteur uniforme obtenue par recouvrement d'un mortiercoulis à base de cendres volantes, a également été développé.

“…Q AS for the SRB-DUP wall can be calculated from friction at the contact plane between a solid element and a horizontal reinforcing plate (Yamaguchi et al, 2005b). Shear stress at the time of slippage can be increased by the prestressing of dry-assembly SRB-DUP walls.…”
