00925njm 22002777a 4500 dc Romera, Jesús María author Marcos, Ignacio author Skaf Revenga, Marta author Ortega López, Vanesa author 2021-10 An alternative experimental method for predicting the diagonal shear cracking resistance of steel-reinforced concrete beams is developed in this paper. Conventional extensometric strain-gauge rosettes are placed on the lateral surfaces of a set of four beams. As diagonal cracking propagates through the beams, the load–strain curves flatten out at a plateau and the mechanical property under consideration may be determined. The method is applied to four beams cast from pumpable and self-compacting concrete mixes with cement types I and IV containing electric arc furnace slag aggregates. The feasibility of applying standard design code formulas to the concretes containing these aggregates may therefore be studied and compared with other recent research works. Accurate experimental results were obtained with this method without having to interrupt the test for subjective visual appraisals of the test specimen. 0141-0296 http://hdl.handle.net/10259/9723 10.1016/j.engstruct.2021.112741 Diagonal shear resistance Steel-reinforced concrete Extensometric gauges Electric arc furnace slag aggregate An alternative experimental methodology to determine the diagonal cracking resistance of steel-reinforced concrete beams
