Author S.K. SUMON Transport Research Laboratory Abstract The introduction of the 40T lorries on I January 1999 by the European Commission Directive means that many of the 40,000 masonry arch highway bridges will need urgent attention. According to 1993 figures it is...
Author O.I. PONOMAREV and A.V. SHAMPUROV TSNIIK, Moscow Abstract The reconstruction and restoration of many architectural monuments and old masonry buildings in the centre of Moscow and in other Russian towns requires a reasonably accurate determination of masonry...
Author G. FRUNZIO and M. MONACO C.I.Be.C. Interdepartmental Centre for Cultural Heritage Engineering, Naples Abstract A large part of the Italian architectural heritage consists of stone masonry buildings. Recent interest in restoration has shown, despite the great...
Author *D.M. LILLEY and **A.V. MARCH *University of Newcastle **Particie Parsons Ltd, Newcastle upon Tyne Abstract Defects in old rubble-filled walls sometimes develop as bows or bulges in one or both outer leaves. These can be the result of rainwater penetration, or...
Author BIRGER GIGLA and FRITZ WENZEL University of Karlsruhe Abstract A research project at the University of Karlsruhe is investigating the bond strength of supplementary injection anchors as a repair method in historic masonry. Such anchors are necessary to carry...
Author D. D’AYALA University of Bath Abstract The paper presents a numerical finite element nonlinear procedure to study crack patterns in masonry buildings subjected to differential settlements. The procedure is applied to the case study of a terraced block in...
Author MASSIMO CORRADI Istituto di Costruzioni – Universita di Genova Abstract This paper has the intent of identifying the disciplinary status and historical basis of the “science of strengthening”. This is a new discipline that, starting from the...
Author EDOUARD G. NESVIJSKI and ODILON P. CAVALHEIRO Federal University of Santa Maria, Brazil Abstract The present paper is devoted to analysis of problems and possibilities of application of some acoustic (sonic and ultrasonic) methods for nondestructive testing of...
Author CLAUDIA NEUWALD-BURG Institut fur Tragkonstruktionen, University of Karlsruhe Abstract For the assessment of the loadbearing capacity of existing brickwork, assumptions on its mechanical behaviour often have to be made when direct testing is not possible to...
Author JAMES C. MYERS Simpson Gumpertz & Heger, Arlington, MA Abstract With the trend to lighter curtain wall systems with independent structural building frames, the risks increase for damaging interactions between the masonry veneer, the back-up wall, and the...
Author JAMES C. MYERS Simpson Gumpertz & Heger Inc., Arlington, MA Abstract An 18h fire severely damaged the structure and masonry facade of a Philadelphia, PA high rise. The facade included solid granite components and granite veneer on precast concrete spandrel...
Author R.P. MURPHY Abstract The paper describes a new system of building in which rectanular bricks in 3 sizes 4/16m, 3116m and 2116m all by l/16m thick and certain shapes are held in place by a 9mm interengagement of pattern depth and a special thin joint adhesive....
Author MERCEDES MARRERO Central University of Venezuela Abstract The technology of the structural concrete block system OMNIBLOCK is described and its comparative advantages against conventional construction with respect to production and assembly. The system relies...
Author W. JAGER and H. BERGANDER Consultants, Dresden Abstract In the standards to prove buckling safety, approximate equations are prescribed which differ in certain fields. The results cannot be assessed by comparing the different approximations. For this purpose, a...
Author A.W. HENDRY Edinburgh Abstract In a paper to the Fourth International Masonry Conference in 1989 the author reviewed the methods adopted in BS 5628 and the draft EC 6, as it stood at that time, for the design of waits under compressive load. In that paper a...
Author A.N. FRIED Kingston University Abstract In the UK design rules for unreinforced laterally loaded wall panels, supported in various ways, have existed for a considerable time. The inclusion of movement joints in these panels will affect the support conditions...
Author S. CLARKE and DJ. HARRIS Kingsway Technology Limited Abstract This Partners in Technology (PiT) project generated data to support the UK National Application Document (NAD) for the voluntary Eurocode for masonry design – ENV1996.1.1. The data was...
Author PETER WALKER University of Bath Abstract Erosion from wind-driven rain is often a major concern for unbaked earthen wall construction. As a result a variety of accelerated tests have been developed to assess material performance. These include subjecting...
Author F. PEAKE, W.A. DUROSE and G.J. EDGELL CERAM Building Technology Abstract A number of test walls have been constructed using two types of facing brick with 75mm cavities formed by an inner leaf of lightweight concrete blocks. The cavities were filled with...
Author R.C. de VEKEY* and G.J. EDGELL** * PORE** CERAM Building Technology Abstract Since 1978 there has been a codified method for designing walls to resist lateral out-of-plane loads in BSS628:Part 1 which is based substantially on empirical data for 28d old...
