Masonry structures are buildings formed by combining brittle
materials such as brick, stone, pumice, and aerated concrete with mortar. The
masonry structures, which do not show the desired ductile behavior against
dynamic effects, show a brittle behavior. This situation causes heavy damage to
masonry structures in the event of exceeding their bearing capacity in the face of
natural disasters such as earthquakes. Knowing the dynamic behavior of masonry
structures will help to take precaution to minimize the loss of life and property,
since a significant part of people live in masonry buildings. The natural
frequency, mode shape and damping ratios of the structures are determined by
analytical and experimental methods, depending on the dynamic properties of the
structures under dynamic loads. In this study, the changes in the dynamic
characteristics of a ½ scale single-span and single-story masonry model built with
hollow brick for different damage conditions were investigated. In order to obtain
different damage cases, the model is tested on a shaking table with gradually
different earthquake data. In order to observe the earthquake damages
experimentally, the modal parameters of the masonry model were determined by
ambient vibration tests for undamaged and damaged conditions.
Also, A nonlinear analytical one-story masonry model is developed using finite
element ABAQUS software with macro modelling approach to study the
behavior of Masonry models subjected to different earthquakes. Six different test
cases using same model are investigated analytically.
