FROM RELATIVE TO EXACT MODEL OF CALCULATION CRACK RESISTANCE OF REINFORCED CONCRETE SECTION

The article is about the improving the method of calculating crack resistance of ferroconcrete sections in the bending on the base of deformation model. It is offered a formula of the moment of appearing cracks, which can be considered exact for its adequacy to the experiment. With due regard for influence of reinforcing at the moment of appearing cracks will improve technical-economical effectiveness and durability of ferro-concrete constructions, calculating limited conditions of which are depended on limitation for appearing and enlarging
