Whole Life Costs of Flexibly Bedded Clay Pavements

Author J. KNAPTON University of Newcastle upon Tyne and I.D. COOK Blockleys Brick Limited Abstract The life cycle cost of roads and similar paved areas surfaced with flexibly bedded pavers is considered in terms of initial construction cost, maintenance costs and...

Innovations in the Brick Laying Process on the Building Site

Author MICHAEL H. M. NIEUWENHUYS, Royal Association of Dutch Clay Brick Manufacturers Abstract Brickwork is considered to be uneconomic because of the cost of the hand operations associated with it. The KNB decided to ignore new mechanised methods of erection and...

Building with Calcium Silicate Elements

Author W.G.J. BERKERS Research Centre for the Dutch Calcium Silicate Brick Industry Abstract Until the Seventies the Dutch calcium silicate brick industry produced bricks and small blocks. It was then realised that bricklaying would lose competitiveness as a...

The Use of Aircrete Blocks in Suspended Floors

Author C.A. FUDGE AND A.H. RIZA Kingsway Technology Limited Abstract In the late 1980s, investigations took place to examine the use of autoclaved aerated concrete (Aircrete) blocks used between precast prestressed concrete inverted T beams to form a suspended floor....

The Behaviour of Skewed Brickwork Arch Bridges

Author C. MELBOURNE Bolton Institute and J.A. HODGSON L.G. Mouchel and Partners seconded to Ballon Institute Abstract A series of test on skewed brickwork arch bridges is described and compared with a similar series of tests on square span brickwork arch bridges....

The Behaviour of Open Spandrel Masonry Arch Bridges

Author C.MELBOURNE and H.TAO Bolton Institute Abstract The paper deals with the general behaviour of open spandrel arch bridges by using finite element methods. Several models and load cases are studied. The results indicate that the stiffness of the main arch is...

Masonry Arch Design at the End of the 19th Century

Author A.W. HENDRY University of Edinburgh Abstract Perception of the structural behaviour of masonry arches dates back to the early 18th century and methods for the design of arch bridges were developed through the 19th century in the course of which many thousands...

Cracking of Brickwork Shear Walls

Author SONGBO LI, A.N. FRIED AND J.J. ROBERTS Kingston University Abstract The test results from 59 brickwork wails under horizontal cyclic loading are examined and compared with the findings from other researchers. Analysis of the cause of cracking is used to develop...

Dry-stone walls

Author PETER WALKER University of New England, Armidale, NSW, Australia JOHN DICKENS University of Technology, Loughborough Abstract Dry-stone walls are an ancient and widespread form of masonry construction. In 1987 approximately 50% of all highway retaining walls in...

Bond Strength of Bed Joints in Solid Concrete Block Masonry

Author DAVID M F ORR AND JOHN COSTELLOE, University College Cork Abstract A bond wrench apparatus has been developed for testing bed joints between solid concrete block masonry units. The apparatus has been used to obtain data for an investigation into the effect of...

Flexural Behaviour of Masonry in Different Directions

Author ROB VAN DER PLUIJM, HARRY S. RUTTEN, AND COR S. SCHIEBROEK Eindhoven University of Technology Abstract The main variable in the experimental research with masonry wallettes tested in flexure, was the angle between bending axis and bed joints. Two types of...

Author C. SOUTHCOMBE University of Plymouth I.M. MAY Heriot-Watt University and V.L. CHONG China Institute of Technology and Commerce Abstract The paper presents the results of an experimental investigation into the behaviour of laterally loaded, single leaf and...

Tests on Masonry Walls with Openings Subjected to In-Plane Loads

Author G.KONIG1, A.OTES2 and M. ERNST1 1 Technische Hochschule Darmstadt 2 Ingenieurburo Konig & Heunisch, Frankfurt Abstract This paper gives the first results of tests on unreinforced and reinforced masonry walls with openings. The walls were built with...

Impact testing of masonry walls

Author MATTHEW GILBERT University of Sheffield, and BRIAN HOBBS University of Teesside Abstract This paper describes the ongoing programme of impact testing on full-scale unreinforced masonry walls constructed in the laboratory at the University of Teesside. A novel...

Gust Loading of Storey Height Walls

Author W.A.FERGUSON Building Research Establishment and G.J.EDGELL British Ceramic Research Limited Abstract The performance of laterally loaded masonry is normally measured by static loading, using airbags. It has been suggested that it might be enhanced if the load...
