Experimental researches of multifaceted composite structures based on self-compacting concrete under axial compression
Abstract: The paper describes the principle of mechanical tests aimed at determining the physical and mechanical properties of self-compacting concrete В20 и В30 (according to Spanish methodologies). Bearing capacity and a character of destruction 6 and 12-sides composite (concrete-filled tubes) elements under axial compression has been experimentally found out. The order of destruction of materials and specific types of destruction the multifaceted composite elements, such as the development of plastic deformations of the steel pipe, and the severance of longitudinal welds have been given. The comparison of results of determining of the bearing capacity of concrete-filled poles, indicating to its overestimation by the analytical and the finite element calculation to 30 % has been carried out.
Keywords: multifaceted composite poles, self-compacting concrete, mechanical tests, axial compression, physic and mechanical characteristics of concrete, nature of destruction, bearing capacity.
