According to the AASHTO LRFD Bridge Design Specifications, minimum reinforcement provisions are intended to reduce the probability of brittle failure by providing Minimum and Maximum Reinforcement Ratios for Flexural flexural reinforcementMaximum Flexural Reinforcement by 2008 MSJC Code. The 2008 MSJC Code has a maximum reinforcement requirement (Sec. 126.96.36.199) that is intended to ensure ductile behavior over a range of axial loads. As compressive axial load increases, the maximum permissible reinforcement Minimum and Maximum Reinforcement Ratio in Different flexural reinforcement1. Minimum Reinforcement Ratio in Beams. In reinforced concrete beams, if the cracked sections flexural strength is lower than the moment that produced cracking of the previously uncracked section, then the beam would fail upon the formation of the first flexural crack, without showing any distress.
However, whereas shrinkage and temperature reinforcement is permitted to be distributed between the two faces of the slab as deemed appropriate for specific conditions, minimum flexural reinforcement should be placed as close as practicable to the face of the concrete in tension due to applied loads".Yes, all ambiguity has been removed flexural reinforcement. Though I imaging the next code cycle will change it again, to allow the other interpretation for foundat flexural reinforcementLet's hope you imagine wrong, JoshPlum. The two requirements, for shrinkage reinforcement and for flexural reinforcement, should be separate.Not quite was I was saying: Rather, I expect the next version of the code to allow As_min to be ignored if 4/3*As_required is provided (like we all flexural reinforcementIf we are talking about mat foundations, they are heavily restrained, so 0.0018 Ag is not enough crack prevention reinforcement.
