Objective

The overall objective of the proposed research is to develop a better understanding of the fundamental behaviour of masonry to enable engineers to: a) design safer and more economical structures and b) design appropriate repair or strengthening measures for existing structures.

The following specific objectives will be achieved:-
To develop an existing constitutive model for masonry to account for microcracking resulting from excessive applied static and dynamic loads;
To develop two complimentary approaches (discrete and continuum models) for the finite element modelling of undamaged and damaged masonry structures subjected to static and dynamic loading;
To carry out a set of non-trivial static load experiments that will be for the identification of material parameters in the constitutive model;
To develop a novel identification technique based on a multi-point approximation method;
To carry out a specialist experimental programme of high velocity blast loading on wall panels in order to validate the numerical models;
To determine the range of applicability of the two aforementioned approaches to the numerical modelling of masonry.

In summary, it is proposed to develop a fundamentally new approach to the modelling and analysis of large-scale undamaged and damaged masonry structures subjected to static and dynamic loading. The proposed work will help researchers and practising engineers to gain a better understanding of the behaviour of plain and reinforced masonry structures leading to more economical and safer designs. Not only can the constitutive model be used in the analysis and design of a variety of new masonry structures, but it can also be used to determine the most effective means of repairing, stabilising and strengthening existing structures ranging from historic monuments, arch bridges and masonry buildings of architectural importance to domestic properties suffering from the effects of ground movement. The proposed work covers masonry structures subjected to dynamic as well as static loading. This should provide a better understanding of masonry behaviour when subjected to vehicle impact and explosions resulting from terrorist activity. The results of this work should be particularly useful for the designers of repair and retrofit systems for existing masonry structures.
