EXPERIMENTAL RESEARCH OF SHEAR JOINT STIFFNESS FOR A REINFORCED CONCRETE STRUCTURE WITH FLEXIBLE PINES
The proposed work presents the results of full-scale shear joint tests performed on volumetric models with the most common type of connection of a reinforced concrete slab with a steel beam using flexible pin stops. In this case, the exclusion of adhesion of the reinforced concrete slab to the steel beam is achieved by the use of an insulating strip. Based on the test results, a graphical relationship between deformations and plate shear forces is constructed. The obtained experimental values of the shear stiffness of the joint are compared with those calculated analytically, as well as using a numerical model using the FEM. The results of experimental studies confirm the reliability of the developed analytical approach used to determine the linear shear stiffness of the joint with flexible pin stops.
