Panel construction has played an important role in building construction in recent decades. These buildings are different from the conventional frame structures because of lack of usual beam and column elements. It seems that structural engineers have reservations in using these construction systems, due to some ambiguities in the seismic behavior and specially in choosing the proper value for the seismic response modification factor. Study of this factor in panel buildings dealt with in this paper by investigation on three different panel structures with similar plan layouts and different heights. PERFORM-3D software is employed to model the nonlinear behavior of these structures with the capability of finite element analysis by making use of the multilayer fiber section shell elements. Doing so, the response modification factors are calculated and discussed. According to the drawn conclusions, it seems that there exist a considerable difference between the obtained results and the values suggested by the related standards, which implies a need for revision due to apparently excess conservatism.

The use of prefabricated panels is one of the new methods of building construction, which has recently been used in the construction of interior and exterior walls, loaders and separators, as well as flooring in construction. This system includes two layers of welded wire mesh. On both sides, a layer of polystyrene is placed and connected to each other by cutters. In the next step, shotcrete concrete is sprayed on these wires and then the surface is polished. The use of 3D panels is increasing due to the importance of lightening, optimizing and saving fuel consumption. In this paper, the combined system of steel frame and lightweight prefabricated panels in the distance from the frame under cyclic loading is analyzed numerically and laboratory. The columns of the frames used are 2IPE120 and the beams are IPE120 and the wall has a height of 120 cm, a width of 64 cm and a thickness of 14 cm, which includes two layers of concrete with a thickness of 4 cm and a layer of polystyrene with a thickness of 6 cm. Numerical analysis is performed with the help of Perform software and in the next step, the formability obtained from numerical and laboratory analysis is compared. Combining a 3D panel system with a bending frame will increase the stiffness and lateral strength of the structure.
