ConcreteSection will help you design complex reinforced concrete sections. ConcreteSection will take care of the modeling details while you specify the location and size of steel reinforcement. The software will analyze your concrete model to determine the 3D interaction diagram, concrete stresses and strains, and reinforcement stresses. ConcreteSection also performs design checks using ACI or CSA strength reduction factors by calculating a moment unity value based on the applied loading and the interaction surface.
