Strength and reliability os splined joints

Abstract

The article presents the results of studying reliability of precast concrete floors’ interplate joints. The author concludes that the normative limits of the number of working splines in the joints require considering the dependence on the reliability of the joints from the number of failures of individual splines. There is implemented an analysis of probabilistic models of single concrete splines and splined joints. The models take into account the influence of efforts’ redistribution in the result of refusal of the individual splines. There is an example of calculating the reliability of joints.
