Title of the articleCrack resistance in the contact joints of columns
Abstract.Currently, there is no standard approach to the calculation of the joints on the emergence and expansion of cracks. However, the norms prescribed to perform the calculation of reinforced concrete structures for the second group of limit states. Multivariate theoretical, computer and experimental studies, as well as inspection of building structures, indicate the need to perform such a calculation. Therefore, the aim of the work is to establish a methodology for calculating the contact joints on the emergence and expansion of cracks. The article presents the results of experimental studies crack resistance crushing zone of concrete columns reinforced with transverse reinforcement. The compressive force directed along a column axis, and eccentricity. For the analysis of applied research concrete resistance to compression theory and nonlinear deformation model. The individual results of theoretical and numerical studies have been published previously. During the experiment, the results of numerical and theoretical studies have been confirmed. The general regularities, composed dependencies specified application limits for the calculation methodology. According to information received revised formulas, supplemented by recommendations on designing.
Keywords.column, contact joint, occurrence of cracks, crack opening, the method, the power of resistance of concrete compression theory, nonlinear deformation model.
