Özet
96% of the available buildings in use in Turkey are taking place in the earthquake zone and approximately 50% of them an masonry structures built using bricks. Sliding shear strength and internal friction coefficient were taken as a constant value in Turkish Earthquake Code (TSC 2007) depending on the type and hole rate of the brick section regardless of available compressive strength of the brick, mortar and plaster of a wall. But nowadays these values are recommended to be taken according to the compressive strength of mortar in TSC-2018. In addition, with this study it is recommended that, to evaluate the performance of a building against earthquake, the mechanical properties of the materials used for a building must be determined on site with series of tests. It is well-known that for each building mechanical properties of mortar and plaster are variable because of site work conditions.In this study, a couple of tests were conducted in different storeys of a five-storey-masonry building representing the clay brick masonry buildings in the country built in the 1950s, to determine the sliding shear strength and internal friction coefficient, using a similar method to shove test. With the increment of axially vertical load from upper storey to lower storey, the shear capacity in the lower storeys of the buidling are much lower than the respective values in upper storeys. In order to determine a characteristic shear force for the building, it has been revised considering the lowest compressive strength of mortar in the storeys. Related with the internal friction coefficient obtained, a quite good correlation was found between the results and the standards. However, the sliding shear strength was found to be approximately three times higher than TSC 2007 and about two times higher than TSC 2018. This means that, the limits recommended in the standards are much safer than results obtained from the tests.
