Application of deformation model to calculation of reinforced concrete lines on steel profile sheet

The article deals with monolithic reinforced concrete slabs, the fixed formwork and the external reinforcement of which is steel profiled flooring. A method of calculating these plates using the deformation model is proposed as an alternative to the existing method of calculation for the limiting states of the first and second groups. The coefficient of working conditions, which ensures the joint work of profiled flooring, concrete and reinforcement, is taken into account when determining the relative deformations of steel sheet profiled. The developed method of calculation expands the boundaries of the use of the deformation model and allows you to use its advantages for the calculation of concrete slabs.
