STRENGTH  AND  CRACK  RESISTANCE  EVALUATION  OF  REINFORCED  CONCRETE  STRUCTURES  FROM  SNiP  AND  IBC

The paper is dealt with the evaluation of section capacity of reinforced concrete structures subject to static and dynamic stresses, considering the surfaces of strength and crack resistance relation of concrete members using the deformation model. The proposed structural design, which considers the stress and strain structural state using stress-strain diagrams, provides the consensual analysis of ULS and SLS structures. Sequential growth of deformations has been considered in standard sections depending on the type of structural loading. Conditions common to strength ratio of concrete structures have been defined which demonstrate the breaking stress interaction within the whole range of dynamic or static structural stress depending on section shapes, reinforcement properties, strength and deformation properties of concrete and steel, and other parameters. The main regularities of changes in regions and surfaces of strength and crack resistance relation (strength ratio) have been detected in reinforced concrete members subject to the above stated parameters. The software has been developed on the basis of the proposed method that allows to significantly simplify the structural design under static and short term loading.

Key words: reinforced concrete structures; strength; crack resistance; deformation model;strength ratio surface.
