Basic assumptions of Compatible Stress Field Method (CSFM)

Compatible Stress Field Method (CSFM) is an innovative method implemented in IDEA StatiCa Concrete used for the design of reinforced concrete structures. Let’s take a look behind the scenes of our software and see for yourselves that there is no need to be afraid of using CSFM calculations in your projects.

See the introduction video about CSFM and IDEA StatiCa Detail:

CSFM offers much more than just ULS checks. The advanced state of the method is based on modified compression field theory, implementation of tension stiffening, and distinguishing between stabilized or non-stabilized cracking; hence we perform SLS checks of the concrete member. Thus, we can observe crack width, deformation, and stresses corresponding to SLS combinations.

Watch the recording of a webinar where the theory behind the CSFM was explained in detail.
