Construction on Contaminated Land

Author S. GARVIN Building Research Establishment, Scotland Abstract There are estimated to be some 100,000 contaminated land sites in the UK resulting from the decline in heavy industry over the past 30 years. The extent and types of contamination may vary not only...

Collapse Modes of Masonry Arch Bridges

Author THOMAS E. BOOTHBY The Pennsylvania State University Abstract The upper and lower bound theorems of plasticity have been shown to apply to the limit states analysis of the masonry arch. To apply the lower bound theorem, it suffices to find a distribution of...

On the Modulus of Elasticity for Masonry

Author H. H. KNUTSSON and J. NIELSEN Danish Building Research Institute Abstract The theory of elasticity is often applied to the design of masonry structures. For such applications it is necessary to know the modulus of elasticity and the ultimate strength. It has...

Creep Measured in a Brick Masonry Tower Block

Author T.G. HUGHES and R.J. HARVEY University of Wales, Cardiff Abstract Strains measured in a highly stressed internal wall of a nine storey structural brick masonry tower block are reported over a period of some 6000 d. Both mechanical and vibrating wire acoustic...

Numerical Evaluation of Bond Tests on Masonry

Author ROB VAN DER PLUIJM TNO Building and Construction Research/Eindhoven University of Technology Abstract Numerical evaluations of flexural and tensile bond tests are presented. An important conclusion is that cross-couplet testing is not reliable since too many...

Experimental Research to Characterise Masonry Materials

Author LUIGIA BINDA, CLAUDIA TIRABOSCHI and SILVIA ABBANEO Politechnico di Milano, Italy Abstract In the last decade or so the characterization of masonry materials by mechanical tests has been much discussed and tests proposed for masonry units, mortars and for...

Properties of Some Clay Bricks Under Varying Loading Conditions

Author A.T.VERMELTFOORT University of Technology Eindhoven Abstract The design of loadbearing masonry structures requires a detailed knowledge of the mechanical properties of the bricks for the project under consideration. Loadbearing masonry is largely subjected to...

A Design Procedure for Cavity and Veneer Wall Ties

Author A.W. PAGE, J. KAUTTO, P.W. KLEEMAN The University of Newcastle, NSW Abstract Wall ties are an essential component of cavity or veneer walls. The behaviour of these walls is complex and a function of the relative stiffness of the outer and inner leaves, the...

Tests of Swedish Masonry

Author LARS SENTLER Lund University Abstract Strength characteristics have been determined for Swedish masonry based on CEN standards to meet Eurocode 6 requirements. Tests include compressive andflexural tests parallel and perpendicular to bed joints and shear tests...
