The random dynamic forces experienced by structure due to wind are caused primarily by the turbulence in the approaching flow and motion of the structure. In the paper, fluctuating wind velocity for time history analysis are simulated by multi-dimensional random processes using Karman spectrum about along-wind direction and Liang spectrum about across-wind direction. This paper is analyzed and obtained the dynamic response for structures modeled as a plane frame. This study uses the stiffness method and static condensation method to determine the condensed stiffness matrix that corresponds to the lateral displacement coordinates at the various levels of the building. The numerical results, obtained by the Newmark-β method, shows the time- history responses and trends of maximum accelerations and displacements by applying various load conditions. In the paper, the values of dynamic reponse to the structure modeled as a plane frame will be discussed with the values of dynamic reponse to the structures modeled as a shear building. For the building that is modeled as a plane frame, lateral displacements and accelerations are greater than the values obtained in modeled as a shear building.
