Abstract
The article combines methods for calculating the main resistance parameters of reinforced concrete structures: a deformation calculation model of the cross section based on diagrams of concrete and reinforcement deformation, a block model based on the law of reinforcement adhesion with concrete and a finite element method for calculating internal forces. Using the example of a continuous beam, the possibility of calculating the parameters of the stress-strain state in any cross-section, at any stage of the construction, avoiding the use of empirical dependencies, is shown.
A simulation of the work of reinforced concrete with cracks during bending is performed. An algorithm is presented for calculating the parameters of the stress-strain state of an uncut bent structure under the action of a load with modeling of the equivalent equilibrium state of the cross section during crack formation. Comparison of experimental and calculated parameters of a statically indeterminate reinforced concrete beam is performed. The directions of further research are determined.
