Abstract
The results of experimental studies of reinforced concrete constructions at complex resistance to torsion with bending are shown in the article. The main purposes of the researches are detection of regularities and determination of deformation and cracking parameters. The most important of the studding parameters are cracking load, destructive load, the coordinates of spatial cracks formation, the width of crack's opening at the axis of the longitudinal and transverse tensile reinforcement and along the entire profile of cracks; changing the distance be- tween the cracks and crack length according to increasing the deformation load; deformation of compressed concrete and reinforcement in a complex stress-strain state. The test results are presented in the form of relationships of structure's deflections, deformations of compressed concrete and reinforcement, including results which were determined by the indications of electrotensometric sockets. The obtained relationships allow us to assess the reliability of the calculating methods reinforced concrete constructions subjected the action torsion and bend- ing.
