摘      要：When evaluating the seismic safety and reliability of complex engineering structures,it is a critical problem to reasonably consider the randomness and multi-dimensional nature of ground *** this end,a proposed modeling strategy of multi-dimensional stochastic earthquakes is addressed in this *** improved seismic model has several merits that enable it to better provide seismic analyses of ***,at first,the ground motion model is compatible with the design response ***,the evolutionary power spectrum involved in the model and the design response spectrum are constructed accordingly with sufficient consideration of the correlation between different seismic ***,the random function-based dimension-reduction representation is applied,by which seismic modeling is established,with three elementary random *** simulations of multi-dimensional stochastic ground motions in a specific design scenario indicate the effectiveness of the proposed modeling ***,the multi-dimensional seismic response and the global reliability of a high-rise frame-core tube structure is discussed in detail to further illustrate the engineering applicability of the proposed *** analytical investigations demonstrate that the suggested stochastic model of multi-dimensional ground motion is available for accurate seismic response analysis and dynamic reliability assessment of complex engineering structures for performance-based seismic resistance design.
