Eccentric Dowels Loaded against Core of Concrete Sections
Publication: Journal of Structural Engineering
Volume 116, Issue 10
Abstract
A simple analytical model is developed for the prediction of maximum dowel resistance of bars eccentrically placed in concrete cross sections and loaded against the core of the section. According to the model, the maximum dowel resistance of bars having large bottom cover (i.e., when the appearance of bottom splitting cracks is excluded) is a function of the bar diameter, the compressive strength of concrete, the yield stress of steel, as well as the top and the side cover of the bar. The validity of the model is checked by means of a series of tests. The role of several parameters, such as bar diameter, compressive strength of concrete, and yield stress of steel have been thoroughly investigated by researchers. The only parameters considered throughout the present experimental work are the top and the side cover of the bar. It is proved that the maximum dowel resistance values predicted by means of the developed model fit satisfactorily the experimental results.
