Abstract

Finite element modelling and analysis has been performed on 103-years old unreinforced masonry Senate hall building (SHB), Allahabad University, India. It is an Indo-Saracenic style of architecture which was built in 1915. An in-situ survey is conducted to know the present condition of the SHB. The major and minor cracks are visible, and construction material has deteriorated at various part of the SHB. The old documents, reports, on-site measurement, and photographs are used to gather the historical data and prepared the accurate model of the SHB on Ansys workbench (ANSYS 14.0) tool. Macro and homogenisation approach has used in the modelling of the SHB. The standard gravity and wind load analysis is performed with a fixed boundary condition on its based of SHB. In gravity analysis, maximum stress (5.69MPa) has been observed at the connections of the ground floor and maximum deformation (7.8mm) on the crown of the arch of the first-floor. The maximum stress and deformation 14.286MPa and 12.491mm have been observed under live load analysis. Further, the maximum stress and deformation obtained under wind load analysis are 4.10MPa and 8.07mm, respectively. The finite element simulation and visual inspection of the SHB are in good agreement with the present condition of the structure.
