Abstract:
Most of the reinforced concrete slab structures are statically indeterminate systems. In these systems the redistribution of internal forces depends on the nature redistribution of rigidities between their separate elements. The presence of cracks significantly affects the change of elements rigidity of reinforced concrete structures. In the plate-ribbed systems, which include bridge structures, ribbed prefabricated and monolithic ceilings, at the moment when normal cracks are wide enough, spatial torsion cracks may be absent. This technique aimed at determination of the torsional rigidity of rectangular section elements with normal cracks widens the spectrum of researches on the strength and deformability of reinforced concrete elements. The goal of the present research is to improve the methodology for determin-ing the movement of a reinforced concrete element of the rectangular cross-section with normal cracks. In this case, the end of the rod is loaded with a torque on the section part.
