Yamaguchi, K; Matsufuji, Y and Koyama, T (2007) A new structural system: Friction-resistant dry-masonry. Building Research & Information, 35(6), pp. 616-628. ISSN 0961-3218
Abstract
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.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
