The aim of this study is to examine the behavior of the historic masonry walls by analyzing both the experimental and numerical results. In the experimental part of the study, original material parameters used in repair, strengthening and restoration of historical monuments were determined. For this purpose, in the context of the research Project numbered as 111M568; the characteristics of the original building materials for the brick and mortar specimens from two distinct historical monuments that are located in Turkey were obtained. Physical and mechanical properties of these materials were calculated and in the direction of this results, new mortars were produced. New masonry walls were constructed with the clay bricks and different types of produced mortar. The experimental walls were subjected to compression and incremental lateral loads and the results were evaluated within the load-displacement relations. Experimental walls were modelled with a new approach called 'fictitious joint material' in which the constitutive behavior of the mortar joint and the brick-mortar interface were included together. In this scope of this work, an elasto-plastic damage (EPD) approach is adapted calibrating the parameters of Oliver's damage model [1] together with the modified von-Mises yield criterion for the masonry constituents.
