Author G.J. EDGELL British Ceramic Research Limited Abstract The British Standard Code of Practice, BS5628:Part 1, allows a designer to enhance the stiffness of an inner leaf of a cavity wall loaded in compression to account for the increased resistance to lateral...
Author W.J. BERANEKand G.J. HOBBLEMAN University of Technology, Delft Abstract A new approach for modelling of brittle materials is suggested: (i) the continuum is replaced by a geometrical configuration of solid sph eres with small contact zones between them; (ii)...
Author JR. RIDDINGTON and P. JUKES University of Sussex Abstract A test method has been proposed that will allow the bond shear strength T0 and the coefficient of friction u of masonry joints to be measured using relatively simple apparatus. A programme is being...
Author AW. HENDRY University of Edinburgh and T.C. LIAUW University of Hong Kong Abstract A cooperative project between the Universities of Hong Kong and Edinburgh was set up in 1987 with the object of investigating possible means of increasing the effectiveness of...
Author R.D. FLANAGAN Martin Marietta Energy Systems Inc and R.M. BENNETT University of Tennessee Abstract The effect of out-of-plane inter-storey drift on the in-plane capacity of unreinforced hollow day block infilled frames was evaluated by testing three large-scale...
Author C. AMADIO and S. RAJGELJ University of Trieste Abstract An experimental study of the behaviour of hollow clay brick masonry under monotonic racking toad with different levels of precompression is described. The specimens have been constructed with units having...
Author HILMAR WERNER SINUSTAT Building Systems, Berlin Abstract The SINUSTAT System is based on hollow calcium silicate building blocks which are designed to be laid stacked up without mortar thus saving the time of traditional bricklaying. Connections ensure precise...
Author O. PFEFFERMANN Studiebureau BTC and B.A. HASELTINE Jenkins and Potter Abstract A survey of damage to buildings carried out by the CSTC Belgium in 1965 showed that more than 40% of the problems were cracks in the masonry. This led to the development of Murfor, a...
Author S. OSMOND Building Research Establishment Abstract At present there is no formal national record of free-standing wall failures in the United Kingdom. BRE has recently produced guidance on the building of free-standing walls, and in the light of this it was...
Author ECKERD KOBER AND CHRJSTOPH JACOB Hebel AG, Germany. Abstract The use of larger units is well known to improve the productivity of laying. Thin layer mortar further improves economy. Two Hebel units are large format blocks (8/m2) and Jumbo blocks 998 x 623 or...
Author MARK WHITBY Whitby and Bird, Engineers, London Abstract The paper asks why are modern buildings like they are and why do we have such a problem making them like they were. Near the beginning of the century Corbusier eulogised the engineer and thought that...
Author WILLIAM B. FAIRLEY, Analysis and Inference Inc.Swarthmore, PA. ALAN J. IZENMAN Temple University, Philadelphia, PA. and A.RHETT WHITLOCK KCI Technologies,Inc.,Manassas,VA. Abstract Investigations of failures of materials or systems aim to determine the causes...
Author J.D.BASTON-PITT GB Geotechnics Limited Abstract Impulse radar is a non-destructive method of investigation for old buildings. The paper describes the principles and the role of the technology in locating and identifying such characteristics as thickness of...
Author W.A.FERGUSON, Building Research Establishment. Abstract The screw pull-out test is being developed to provide a simple, inexpensive method of assessing the quality of both building mortar and units used in masonry. The test measures the shear strength of a...
Author R. CERIONI, G. DONIDA, A. FARINA and A. SPAGNOLI University of Parma Abstract Preserving historical and cultural monuments and planning possible restoration makes investigations of the structural damage a priority in order to provide a diagnosis of the overall...
Author A.D. BUENO, P.C. PHILIPPI, R. LAMBERTS Federal University of Santa Catarina, Brazil Abstract Moisture is responsible for mould growth and affects the mechanical resistance, aesthetics and durability of building materials. Permeability to water vapour and heat...
Author J.A. TINKER, University of Leeds and A.O’ROURKE. The Nottingham Trent University Abstract Although the UK Building Regulations state that the mortar joint can be ignored when the U-value of a wall is calculated, by doing this, the U-values quoted for the...
Author W.R.MILLARD Marley Building Materials Abstract Data from major European manufacturers of AAC are used together with test results obtained on their materials in NAM AS accredited laboratories in UK to determine the parameters which influence thermal conductivity...
Author H.E. JENSEN Technical University of Denmark Abstract This investigation was undertaken to show the influence of an unloaded leaf on the load-carrying capacity of a cavity wall and the magnitude of that influence. Tests on 23 full-scale cavity and single walls...
Author J.P. FORTH and J.J. BROOKS University of Leeds Abstract Further test data have been obtained on the influence of geometry on creep and moisture movement strain of clay brickwork watts and piers constructed from Fletton, Dorket Honey gold and Nori clay units....
