Numerical and experimental investigation of fitting tolerance effects on bearing strength of CFRP/Al single-lap blind riveted joints

In this study, an experimental investigation was carried out, in order to study pin- bearing strength, failure modes under various clamping moments depending on the geometrical parameters. Two different geometrical parameters were investigated. For that reason, the ratio of the distance from the pin centre to the top edge top in diameter (E/D), and the ratio of the specimen width to the pin diameter (W/D) were suitably varied, in order to verify their influence on the failure modes consisting of net-tension, cleavage and bearing. Totally, 160 specimens were tested. The mechanical properties of prepreg composite were obtained from standard tests. Experimental results showed that failure modes and bearing strengths were strictly influenced from increasing value of applied clamping moments and geometrical parameters.

The paper considers the change of load-bearing strength and deflections of corrosion-damaged precast reinforced concrete floor slabs in the conditions of cyclic freezing-thawing in full-scale climatic conditions. The aim of the study is to determine the influence of the depth of tensile concrete deterioration on the change in load-bearing strength and deflections. Corrosion-damaged precast reinforced concrete floor slabs were selected and experimental investigation was performed. Based on the results of the study, the influence of the depth of deterioration of tensile zone of concrete on the load-bearing strength and deflections of structures was determined. At the same time, as the loads increase, deflections increase and the height of the compressive zone decreases. In the experimental investigation, changes of the load-bearing strength and deflections of precast reinforced concrete slabs were determined, depending on the depth of tensile concrete deterioration. The performed studies allow us to estimate the load-bearing strength and deflection values of corrosion-damaged reinforced concrete slabs depending on the relative value of the concrete deterioration in the tensile zone without performing additional experiments and calculations.
