The shear connection is possible modeled using a special load device called "Patch load". This entity is capable of distributed point load over an effective radius (area) which is defined by the user.
The option when the force is transferred directly to the concrete or reinforcement bars is derived from the realization of the connection in the wall. We have used the option for direct transfer to the reinforcement bars due to the effect of welding the anchors to the wire-fabrics. It is really important to realize that the shear joint transfers, apart from the vertical load, also bending moment out of the plane the wall. This effect cannot be covered in the 2D model in IDEA StatiCa Detail.
