Abstract: This paper presents the results of 48 tests that were performed to gain evidence concerning the dowel action of titanium bars connecting marble elements. The parameters investigated within the program were: the diameter of titanium bars (6, 8, 10 and 12 mm), their cover (2, 4 or 6 bar diameters), as well as the loading direction (against the strong or the weak direction of marble’s anisotropy). The main aim of the testing program was to determine the minimum cover required to ensure that failure will occur in the titanium bar and not in the marble. It was proved that a cover equal to 6 times the dowel diameter is sufficient to ensure dowel failure, whereas for loading against the marble’s strong direction, even a cover of 4 times the bar diameter is sufficient. Adequate formulae, calibrated on the basis of the experimental results, are proposed for the calculation of the dowel resistance.
