Crumb rubber concrete (CRC) is made by adding rubber crumbs into conventional concrete, and many studies show that ultimate compressive strains for CRC are much bigger than those for conventional concrete. This article undertakes a mechanical analysis of a reinforced beam based on a proposed CRC stress-strain relationship. The results show that, assuming identical geometrical and material conditions, CRC beam can support more external moment than what conventional concrete beams can do.

Frp Bars

Based on the non-linearity stress strain relation of concrete, the cracking moment of plain flexural concrete member is established, and the flexural capacity of concrete beams reinforced with FRP bars is also obtained under FRP rupture-controlled failure. To prevent FRP rupture failure upon concrete cracking, the minimum reinforcement ration should be derived from simplified calculation, which may provide some theoretic guidance on design and construction for concrete structure reinforced with FRP bars.

The article illustrates the possibilities of the practical application of the ZI method [1 and 2] when calculating the strength of reinforced concrete beams. The article presents variants of description of the EN-2 regulation curvilinear  diagram for concrete with reliability of 50 % by the ZI method with reliability of 50 %, 95 % and ~100 %. The article demonstrates how, when calculating the strength of normally and abundantly reinforced concrete beams by the ZI method, it is possible to do without the calculation of the limit value of the thickness of the concrete layer of the beam compression zone. This is important in the case of the calculation of the strength of abundantly reinforced beams. The method for calculating the strength of abundantly reinforced beams has been improved. When calculating strength, we also obtain actual values of stress-strain parameters at the crack. The tables provide data supporting the proposed innovations and facilitating calculations.
