Застосування вдосконаленого методу розрахунку похилих перерізів залізобетонних балок

Abstract

The priority task for researchers of building structures is developing methods of calculation, which would allow performing constructions calculations with higher accuracy, preserving the reliability of the design. This especially concerns of calculation inclined cross sections of reinforced concrete beams given their sharp, sudden and brittle fracture and difficult stress strain state. Improving methods for calculating will provide the lower expense of materials when designing reinforced concrete structures and allow more efficient using all elements that make the construction. In this paper an improved methodology for calculating inclined cross sections of concrete structures where transverse reinforcement existent or no, and its testing on similar experimental samples of other researchers is proposed. Statistical testing data of calculation relationships shows their convergence with experimental data and provides conditions for their application at designing or assessment of stress-strain state of inclined cross sections of reinforced concrete constructions. Such verification is showed higher convergence than method of calculation according to current norms. It was selected 16 test samples, which destruction was according to the scheme for shear force. According to the results of theoretical researches it was determined that the discrepancy between the calculations for existing norms and the experiment is over 49,4 %, aside lowering the theoretical results, which is a significant divergence. Improved calculation method showed significantly better convergence. Underreporting theoretical results is not more than 23 %, only one case is 33 %
