Özet
96% of the available buildings in use in Turkey are taking place in theearthquake zone and approximately 50% of them an masonry structures built usingbricks. Sliding shear strength and internal friction coefficient were taken asa constant value in Turkish Earthquake Code (TSC 2007) depending on the typeand hole rate of the brick section regardless of available compressive strengthof the brick, mortar and plaster of a wall. But nowadays these values arerecommended to be taken according to the compressive strength of mortar in TSC-2018.In addition, with this study it is recommended that, to evaluate theperformance of a building against earthquake, the mechanical properties of thematerials used for a building must be determined on site with series of tests. Itis well-known that for each building mechanical properties of mortar and plasterare variable because of site work conditions. In this study, a couple of tests were conducted in differentstoreys of a five-storey-masonry building representing the clay brick masonrybuildings in the country built in the 1950s, to determine the sliding shear strengthand internal frictional coefficient, using a similar method to shove test. Withthe increment of axially vertical load from upper storey to lower storey, theshear capacity occurs in lower storey more than upper storey. In order todetermine a characteristic shear force for the building, it has been revisedconsidering the lowest compressive strength of mortar in the storeys. Relatedwith the internal friction coefficient obtained, a quite good correlation wasfound between the results and the standards. However, the sliding shearstrength was found to be approximately three times higher than TSC 2007 andabout two times higher than TSC 2018. This means that, the limits recommendedin the standards are much safer than results obtained from the tests.
