I am simulating a concrete panel of a building that is exposed to wind load and the proper weight. The panel is fixed to the wall with some steel brackets, the steel brackets are bonded to the panels as showed in the picture below.
The space between the steel and the concrete is full filled with a flexible resin.
I have tested with rigid connection and bonded contact but they have too much stifnness and the results are not realistics.
Anyway, many thanks for your help.
