Abstract: (3331 Views)
According to the latest census of Iran, between 43 and 45 percent of buildings are classified as masonry buildings, of which about one percent are historical-cultural buildings. Protecting these buildings against earthquakes is necessary and obligatory for future generations. To achieve this, analyzing and investigating the building is crucial to provide necessary and appropriate solutions to improve its performance level. The present study investigates the Sadaqiyani house located in the Faculty of Architecture and Urban Planning of the Islamic Arts University of Tabriz. First, by using non-destructive tests, including an in-situ test (double flat jack), the average compressive strength and the modulus of elasticity were obtained at 2.47 MPa and 3735 MPa respectively. Then utilizing 3Muri Software and the equivalent frame method, this building was modeled in three dimensions and subjected to incremental modal pushover analysis. This research aims to evaluate the current state of the mentioned building despite structural interventions. The results of the pushover analysis show that the safety index is greater than one in the Y direction in all three performance levels (NC, SD, DL). However, the safety index in the X direction falls below one. In addition, the maximum shear strength in the Y direction is roughly 1.5 times of X direction. These findings suggest satisfactory performance in the Y direction while the X-direction exhibits vulnerability, necessitating strengthening measures.
