In this paper, the nonlinear-non-elastic behavior of the braced frames of the SCBF Special Center is compared with the BRBF anti-arc bracing brackets. Different structures with different numbers of floors, which were previously designed according to the existing regulations and the recommended behavior coefficient, were non-linear static analysis by OPENSEES software and their load-bearing and cyclic behavior were determined for both types of braces. The effect of stiffness strain percentage and the degree of initial geometric defect of the brace on the behavior of the structures were also investigated. Comparison of results indicates more formable and stable behavior of anti-buckling brace than normal brace. Also, the effect of primary geometric defect is significant only in the initial steps of displacement and the higher the percentage of strain strain strain, the more stable behavior structure against larger forces. it shows.

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.
