The building information was collected by interrogating the three dimensional (3D) laser scan data and by undertaking detailed building inspections. The 3D laser data was modelled in Revit2013 Studio software to measure building dimensions. Figures below show few views of the three dimensional model of the building generated. The model was then investigated and analysed to verify the as-built drawings, member sizing and to identify any building deformations that cannot be detected during a visual inspection.
Samples of the two primary stone types in the structure were taken by coring 75 mm diameter cylinders approximately 160 mm long. These were compression tested to failure, to determine the strength of the material.
Linear modelling based on the Equivalent Frame approach allows the determination of fundamental mode shapes and frequencies, and to predict the behaviour of structure in linear range. The non-linear behaviour of the structure was accounted for in the earthquake action calculations.
