Do you deal with concrete structures consisted of composite members? Do you need to analyze composite beams of type concrete-concrete? Do you puzzle over the design and code-checks of pre-tensioned beams interconnected with cast-in-situ slabs? Do you need to combine pre- and post-tensioned tendons or just two different concrete classes in the cross-section?
If so, IDEA StatiCa is the right tool for having your problem solved!
IDEA StatiCa Beam
Structural engineers are quite often challenged with a task when two concrete composite parts of a beam are cast at different times. This automatically means having a different modulus of elasticity, consecutive load application. In such case, differential creep and shrinkage cause unequal strains and stresses in two adjacent fibers of the construction joint. Thus, the requirement is to ensure that both parts act fully compositely because the bending and shear designs of composite members are based on this assumption.
IDEA StatiCa Beam is the best application on how to model, design and code-check reinforced or prestressed composite beams.
Modeling
Your modeling process of the composite structure would most probably start with the cross-section shapes. There are several types of typical composite cross-sections available.
If you do not find a suitable cross-section, you can always use the powerful feature of IDEA StatiCa - general cross-section. You can analyze any shape of a cross-section, even a composite one.
Load cases
Besides load cases automatically added by the wizard, such as self-weight, superimposed dead and variable load, user-defined forces can be applied on the composite beam, known from your FEA software. Via xml file, you can import internal forces corresponding to temperature and moving load effects defined in FEA software.
