The current research presents a new approach for nonlinear dynamic analysis of reinforced concrete shear wall under seismic loading in ANSYS Mechanical software via adding APDL commands. By applying lateral load, the behavior of reinforced concrete shear wall as a model was analyzed using the proposed method and the maximum bearing load, maximum displacement and the positions of the occurrence of the cracks were determined. Then, this shear wall was analyzed through Response Spectrum Method (RSM) as a linear dynamic method and the results of nonlinear dynamic method were compared with RSM. The results of nonlinear dynamic analysis showed that the maximum loading and its maximum displacement were 276 kN and 2 cm, respectively. However, the maximum displacement obtained by RSM was more than the corresponding value using the proposed nonlinear method, which this is mainly due to the consideration of safety factor in RSM. In addition, the whole capacity of materials is employed in nonlinear analysis, which this issue is not taken into account in RSM.
