Understanding concrete design reinforcement

We develop software for structural engineers and detailers. Our development team researches, tests, and applies new methods of analyzing the behaviour of structures and their members. Based on this, we created IDEA StatiCa – software that enables engineers to work faster, evaluate requirements of the national code thoroughly, and use the optimal amount of material. For us, creating software is a way to contribute to making every new construction around the world safer and cheaper.

Understanding concrete design reinforcement

In order to obtain realistic results in IDEA StatiCa Detail, tension stiffening is accounted using the Tension Chord Model, which is also used for calculating the crack widths (using effective concrete areas compatible with code requirements). The figure below summarises the basic assumptions, including the stress-strain relationships of concrete and reinforcement.
