- Description
- The paper assesses the behavior of a culturally significant unreinforced masonry building in the city of Newcastle, Australia. The building was constructed in 1855 without considering the seismic design due to a lack of available codes and standards for seismic design at that time. The geometry of the building is simulated by finite element method in DIANA 10.2 software considering the nonlinear behav-ior of the masonry material. The performance and seismic vulnerability of the unreinforced masonry structure is determined through linear and nonlinear analyses. The form of the building has been changed over time which converts the type of the structure to a retrofitted masonry building. The effect of retrofitting on the structural factors such as ductility and performance factors as well as the related failure modes are investigated comparing the results of plain versus retrofitted masonry models. The influence of diaphragm flexibility on the behavior was also considered. It was concluded that assuming rigid diaphragm on the floors and the roof of the URM building resulted in more favorable structural behavior than was achieved for the retrofitted structure with the flexible diaphragms. Retrofitting, however, had a considerable impact on the crack widths by improving overall the performance of the structure and positively influencing the modes of failure.
