THE program and methodology OF experimental studies of composite reinforced concrete structures under the action torsion with bending

Abstract

It is proposed the program and methodology of experimental studies of reinforced concrete structures under the action torsion with bending. The main purpose is to check the calculation premises and to determine experimentally design parameters of the proposed calculation method. The program of experimental studies includes testing composite structures of beam and plate types. It was created a pilot installation for the experiment was specially at the Department of Unique Buildings and Structures of the South-Western State University. It allows to create a torque on the investigated sections of the transverse bend and it is able to extinguish it on the support in combination with static test circuits (without requiring special expensive devices). Particular attention is paid to the determination of the angles of rotation and deflections of the calculated cross-sections; schemes for the crack formation, crack development and opening of crack; for the deformation of concrete in difficult stressed areas of reinforced concrete structures under the action torsion with bending.
