Strength and deformability of elements with steel-plate reinforcement with bending cracks

The features of the work composite steel and concrete structure with steel-plate reinforcement during bending are considered. The models are described, the features of the models, materials and their characteristics are given. The description of experimental equipment, schemes of testing and loading of structures is given. Schemes and types of fracture, graphical results of bending tests of models are presented. A comparison of theoretical and experimental data on the first and second groups of limiting states – strength, deflections, and crack opening width, has been performed. An assessment of the existing regulatory approaches in relation to composite steel and concrete structure with steel-plate reinforcement is given. Correction coefficients are proposed for the calculation for the second group of limit states of steel and concrete structure with steel-plate reinforcement.
