Structural assessment and remedial interventions on structural systems of these buildings require special considerations to retain the architectural integrity and historical authenticity. The dynamic analysis and modelling of such structures needs special consideration in terms of material properties and method of analysis, such as, thrust line analysis, discrete element formulation methods and finite element methods (micro or macro modelling). Obtaining the accurate material properties and their appropriate modelling still has some issues in this field of study due to widely varying nature of such type of structures. This paper deals with the method and complexities involved in material as well as structural modelling of historical masonry structures. Introduction The importance of heritage structures from a National standpoint hardly needs expounding. Our built heritage needs conservation from the economic, cultural and environmental viewpoints and the first step towards preservation and restoration of heritage structures involves their structural analysis. Accurate analysis is required in order to arrive at reliable solutions and to avoid unnecessary
