Abstract

In order to reasonably consider the vertical earthquake effects and realize the joint selection of horizontal and vertical ground motions, this paper proposes a joint selection method of horizontal and vertical ground motions based on generalized conditional intensity measure (GCIM). The basic theory of GCIM is extended, the construction method of GCIM distribution for horizontal and vertical ground motions is proposed, and compared with the "unconditional distribution", the theoretical details of the joint selection method of horizontal and vertical ground motions based on GCIM are proposed, the actual calculation example with horizontal IM as the condition is given, and the existing horizontal-horizontal, horizontal-Vertical IM correlation coefficient models are used to construct horizontal and vertical ground motion GCIM target distributions, and joint selection is carried out according to the target ground motion database, and the selection results are compared with the traditional selection method to illustrate the rationality of the method. The results show that there are some differences between the constructed horizontal and vertical GCIM distributions and the "unconditional" distribution; the joint selection results of horizontal and vertical ground motion match well with the target theoretical distribution; compared with the selection method considering only the horizontal GCIM ground motion, the joint selection method can take into account the vertical ground motion characteristics well, and will not affect the horizontal direction. The combined horizontal and vertical ground motion selection method proposed in this paper can consider the horizontal and vertical ground motion characteristics more reasonably and comprehensively, and provide the ground motion input basis for the research of seismic performance of engineering structures under the action of horizontal and vertical ground motion.
