nonlinear vibration analysis of shear wall-frame structure under seismic load

in order to design and model compatible with a structure against lateral forces such as earthquakes, it is necessary to know enough about its behavior under these types of forces. it is worth noting that in order to complete a design, it is not enough simply to guide the instructions and the behavior of a structure against an earthquake is influenced by several factors that are important to know. therefore, other than the case codes, it was necessary to pay attention to natural frequency modes, hysteresis cycle and displacements. in this paper, by modeling the structure of a two-dimensional shear wall-frame under a nonlinear vibrating load, we have tried to extract and display the highest quality diagrams. initially, the natural frequency of the shear wall-frame was obtained from the software 1, 3 and 5 stories. subsequently, the loading history was exerted to the top of the structure, which was finally drawn using force-time, time-displacement, and hysteresis diagrams. the results obtained from the analysis show that the structure of the shear wall-frame is more in vertical direction than the horizontal direction, and there is no lysis of hardness and strength.
