• ### MOMENT CURVATURE ANALYSIS - structsource.com

MOMENT CURVATURE ANALYSIS • Reinforced concrete design calculations normally assume a simple material model for the concrete and reinforcement to determine the moment capacity of a section. The Whitney stress block for concrete along with an elasto-plastic reinforcing steel behavior is the most widely used material model in American codes.

It is demonstrated that in the case of self-compacting concrete (SCC) and slump flow test the measured spread diameter can not be correlated to the yield stress of the SCC tested. An alternative way to measure the yield stress of a given SCC is then presented.
