Hello,
I am looking for a way to make one-sided supports to support a surface or point in only one direction. For example “-Z” a in the opposite direction ensuring freedom of tearing. One-sided supports can be used to model the abutment of steel elements on the concrete surface.
Only given some notes, when bending moment applied at elevation it will produce shear reactions due to eccentricity. Lateral restraint or spring is required to keep stability of structure models. Actually shear force exist as reaction output in global model of frames were not shown in above picture shown.
To study and understand the behavior clearly, it’s common to model with fully solid element in contact and plasticity. i frequently gain convergence for below an hour in such analysis using personal PC.
