Reinforced Masonry Walls Under Blast Loading

Author CHR MAYRHOFER Fraunhofer-lnstitut fur Kurzzeitdynamik Abstract Masonry walls change brittteness and gain ductility with reinforcement in the bed joint. The dynamic force enhancement is ore than a factor of 4 compared to unreinforced brickwork. Reinforced...

Simplified Non-linear Seismic Analysis of Masonry Buildings

Author G. MAGENES and A. DELLA FONTANA University of Pavia Abstract A method for the simplified non-linear seismic analysis (pushover) of unreinforced masonry buildings is presented and discussed. The method is based on an equivalent frame idealization of multistorey...

A Method to Evaluate Damage Under Dynamic Loading

Author A. BACCI and V. LAUDAZI Accademia Navale, Livorno Abstract A simple model is proposed able to evaluate the cyclic degradation of a masonry structure, based only on the measurement of the speed propagation of sonic waves. The masonry material is regarded as a...

A Dynamic Finite Element Modelling Approach for Masonry Structures

Author MATTHEW GILBERT* TOM MOLYNEAUX** and BRIAN HOBBS*** * University of Sheffield **UniveTsity of Liverpool***University of Teesside Abstract A three-dimensional non-linear finite element modelling approach suitable for describing the response of unreinforced...

Eccentrically Loaded Historic Masonry

Author AHMAD SABHA TV Dresden Abstract The proof of structural safety for historic masonry buildings and the evaluation of their bearing capacity according to current codes leads often to underestimation of their actual existing strength. In order to avoid this...

On Some Indirect Methods of Analysis of Shear Walls

Author JAN KUBICA Silesian University of Technology, Gliwice, Poland Abstract The paper deals the analysis of problems with the calculation of masonry shear walls. National standards usually only give general information on analysis of shear walls and only concern...

Capacity of Vertically Sheared Unreinforce Masonry Wallsd

Author JAN KUBICA Silesian University of Technology, Gliwice, Poland Abstract The problems of analysis of stiffening walls of buildings are connected with shearing in the horizontal and vertical directions. Protection of buildings against vertical shear loads is still...

Strength and Deformation Capacity of Laterally Loaded Masonry

Author KLAVS FEILBERG HANSEN Danish Building Research Institute Abstract The results of 16 deformation controlled tests with bending of masonry walls about axes perpendicular to the bed joints are presented. The objective of the tests was to investigate the failure...

A Numerical Study of Masonry Tensile Bond Strength Test Methods

Author J.R. RIDDINGTON, P. JUKES and P.J.B. MORRELL University of Sussex Abstract Many different types of direct tension and flexural tests for determining bond strength have been developed over the years. In this paper the results from finite element analyses of many...

Elastic-brittle Cosserat Continuum Model for Brick Masonry

Author RENATO MASIANI and PATRIZIA TROVALUSCI Universita di Roma La Sapienza Abstract A micropolar continuum equivalent to discrete systems of rigid particles interacting two by two is proposed. It can represent the behaviour of brick/block masonry as well as jointed...

Analysis of Cavity Walls – The Danish Approach

Author MOGENS BUHELT Danish Building Research Institute Abstract The combination wall provides an extension of the concept of the cavity wall. A combination wall consists of two structurally active leaves and a layer of insulation material. The inner leaf generally...

Lime Renders in Southern Portugal

Author MARIA GORET MARGALHA Beja City Hall Abstract Portuguese historic buildings were mainly built using lime mortars, not only as renders, but also as bonding material, together with stone and bricks. Preserving this heritage requires, as in other countries,...

Influence of Fine Materials in Sand on the Rheology of Fresh Mortar

Author P.F.G. BANFILL Heriot-Watt University Abstract Rheology is a key characteristic of fresh mortar since how the material behaves when worked with a trowel governs the quality of the work which the bricklayer can achieve. Sands from different parts of the UK have...
