Analytic modeling of behavior of nonstructural inter-frames in steel frames

Nowadays using nonstructural inter-frames in buildings with metal or concrete frame is inevitable. Past earthquake experience show has shown that investing the effect of this inter-frames in behavior of steel frames is very important. Nevertheless, modeling and viewing this effects is refrained in designing steel structures. Nonstructural insulators change the plasticity and lateral hardness of steel structures which these changes should be viewed with a method in modeling and designing the structures. In this research, first with referencing to a practical experiment on bending steel frames together with nonstructural inter-frames and then by creating its simulated model in ABASQUS software, we have the model validation and then different changes such a change of bending frame to semi-rigid frame, change of bending frame to simple frame with diagonal bracing and also using one-way or two-way plasters in wall are performed in the model and the results have been studied and finally, interaction share of nonstructural inter-frames are determined so the designers pay attention to the importance of the hardness effect of these nonstructural frames in their designs and take into consideration these effects which lead to different behavior in the structures.
