Özet:

Unreinforced masonry construction is still widespread among many urban and rural areas, in developing countries such as Turkey. In order to prevent any loss of lives during an earthquake, ensuring the safety of these buildings is crucial. The buildings which are located in earthquake prone regions should be investigated and assessed so that necessary precautions can be taken. Therefore, several questions and concerns regarding the application of the assessment procedure, the assumptions and risk decision for the current methods of masonry building assessment are raised. This thesis addresses these concerns and investigates the material characteristics of masonry buildings in Turkey and its effect on assessment methods. In this regard, ten buildings were selected for the study and detailed information were collected on the field regarding the selected buildings. After that, preliminary assessments were conducted on the selected buildings according to the method described in RBTEIE (2013) and the results were evaluated. Then, axial compression, diagonal tension and sliding shear tests were conducted in the laboratory, on the wall specimens obtained from the selected buildings. The test results were discussed along with the comparison with the strength values given in TEC (2007) and new material characteristics for masonry buildings were recommended accordingly. Finally, assessment methods described in TEC (2007) and RBTEIE (2013) were conducted to the selected buildings with different material characteristics for all the earthquake zones. The assessment results showed that, the assessments conducted with the allowable stress values provided by TEC (2007) might lead to inaccurate and unsafe results.
