TWISTING RIGIDITY OF REINFORCED CONCRETE ELEMENTS OF I–BEAM SECTION WITH INCLINED CRACKS

Abstract

The article shows that to determine the torsional stiffness of an element, one should first dissect the reinforcement in the place of an inclined crack. After cutting the reinforcement, the mutual displacement of the crack edges should be determined. This problem is the main and most difficult one in the general problem of determining the torsional stiffness of elements with both normal and inclined cracks. The article is devoted to solving just this most difficult part of the problem – determining the mutual displacement of the sides of an inclined crack of an I-beam element.
