Özet
Masonry constructions are edifices created through the amalgamation of fragile substances like stones, bricks, and pumice utilizing mortar. The masonry structures, which do not show the desired ductile behavior against dynamic effects, show a brittle behavior. In scenarios like earthquakes, when masonry structures surpass their load-bearing capabilities, this circumstance leads to heavy damage. Knowing the dynamic behavior of masonry constructions will help to take precaution to minimize the loss of life and property, since a significant part of people live in masonry buildings. Both analytical and experimental methods are employed to determine the damping ratios, natural frequencies and mode shapes of the buildings. which depend on the dynamic properties of the structures subjected to dynamic loads. This study explored variations in the dynamic attributes of a half-scale, single-span, and single-story masonry model constructed with hollow bricks under various damage scenarios. To acquire varying levels of damage cases, the model is tested on a shaking table with gradually different earthquake data. To observe the earthquake damages experimentally, the modal parameters of the masonry model were ascertained through ambient vibration tests conducted under both intact and impaired conditions. Also, A nonlinear analytical one-story masonry model is developed using finite element ABAQUS software with macro modelling methodology for examining the characteristics of masonry models subjected to different earthquakes. Six different test cases using same model are investigated analytically.
