We have felt deep sadness as a country for the earthquakes centered in Kahramanmaraş on February 6, 2023, described as the catastrophe of the century. The earthquakes have caused damage and destruction not only to structures with reinforced concrete load-bearing system, but also to structures with masonry load-bearing system. Within the framework of TÜRKİYE Building Earthquake Code (TBEC-2018), earthquake performance analyses of existing buildings can be performed. In these analyses, structures with masonry load-bearing systems are examined as well as reinforced concrete, steel, prefabricated reinforced concrete structures. The most important analysis parameters in earthquake performance analyzes of masonry structures are the compressive and shear strength values of the bearing walls. These values differ according to the material and mortar properties of the load-bearing walls. Therefore, the material and mechanical properties of load-bearing walls are very effective in evaluating the earthquake performance of masonry structures.
In TBEC-2018, it was stated that masonry load-bearing walls can be produced from brick, heavy or light aggregate concrete, aerated concrete, natural and artificial stone materials. In addition, compressive and shear strength values of load-bearing walls according to different mortar strengths are given in tables. In the first part of our study, based on these values, earthquake performance analyzes were carried out for 3 different masonry building models with different materials and architectural properties. Linear finite element method was used in the analyzes by accepting all the data as constant except for the load-bearing wall material, mechanical properties and earthquake parameters. As a result of the analysis, comparisons were made in terms of the shear capacity of the bearing walls; the story shear capacities and the earthquake performance level of the building. As a result of the comparisons, the effect of different material mechanical properties on the earthquake performance of the new masonry structure or existing masonry building load-bearing walls for different earthquake parameters was evaluated.
In the second part of our study, sustainable new design approaches in masonry building design were investigated. In this context, the development of new masonry building load-bearing walls using recycled of building demolition wastes or mortars with super-absorbent polymer additives were investigated. In order to provide sufficient earthquake performance in masonry structures, the mechanical properties of the new design approaches are detailed. In our further studies, it is aimed to compare the analytically obtained data and findings with experimental results.
