Abstract
An analysis of known methods for evaluation the compressive strength and modulus of elasticity of existing masonry structures have been carried out. A method for determining the mechanical characteristics of masonry, based on tests of the specimens cutted from the body of the masonry in the form of triangular prisms have been given. Comparison of compressive strength, initial shear strength and angle of internal friction, obtained from the results of tests of prism specimens, with the results of tests of masonry specimens in accordance with the standards STB EN 1052-1 and STB EN 1052-3 has been carried out. Satisfactory agreement between the values of the compressive strength of the masonry and the secant modulus of elasticity obtained by testing the prisms with a compressive load acting perpendicular to the plane of the horizontal mortar joints with the test results according to the STB EN 1052-1 method has been shown. The initial shear strength of masonry, obtained from the results of tests according to STB EN 1052-3, differed downward from the strength established from the results of tests of prism specimens for compression, while the values of the angle of internal friction determined by the two methods were close.
