Based on the three-dimensional explicit and implicit partition algorithm,combined with the transfer function,four kinds of soil models with different sites and three kinds of single frame structure models with different floors were established,and the influence of the frame structure on the ground motion under the vertical incidence of SV wave was analyzed.The results show that the influence of the same frame structure on ground motion is significantly different with the change of site conditions,and the influence range becomes smaller with the soil becoming soft,and the influence frequency band becomes narrower and moves to low frequency.The influence of different frame structures on ground motion in the same site becomes complicated as soil becomes soft.The effect of structure on ground motion is positively correlated with the size of structure in classⅠsite.Under the conditions of classⅡandⅢsite,the influence of ground motion is affected by both the frequency band of ground motion and the distance between soil and foundation.In the same frequency band,the positive and negative correlations vary with the distance.The effect of frame structure on ground motion has no significant difference under the condition of class Ⅳ site.
