摘要
结合国内水工结构抗震研究的发展,对近年发表于相关领域的国际期刊杂志的工程抗震研究最新发展进行调研。伴随实际强震、近震地震动记录及震害资料的不断丰富,工程抗震研究也得到了不断深入,近期国内外在工程抗震的关注点主要包括基于性能的抗震设计、设计地震动参数的确定、近断层地震动的脉冲特征、地震动持时对结构地震损伤的影响、增量动力分析、混凝土大坝开裂后的动力稳定、地震动时空非均匀性对拱坝地震响应的影响等方面,本文对上述关注点进行了概括总结。
Recent developments and attractive research areas in aseismic design of hydraulic structure are summarized upon reviewing papers published on journals abroad in the field of earthquake engineering. The main attentions are given to the performance-based design, determination of seismic parameters, pulse characters of near field strong ground motion, influence of duration of strong ground motion on structure damages, incremental dynamic analysis, dynamic stability of detached concrete dam, and responses of arch dams to non-uniformly distributed ground motion.
