The purpose of this study is to conduct the dynamic response analysis of concrete structures with long natural period using the earthquake ground motions simulated to huge earthquakes of off-shore type dominated by long periodic wave and to evaluate the seismic resistance of these structures.The following results were obtained in this study.(1)The seismic waves of Tokachioki Earthquake in 2003 and other huge earthquakes of off-shore type dominated by long periodic wave were developed using the simulation technique, EMPR, for non-stationary strong motion time histories on the upper surface of so-called engineering basement rock.(2)The nonlinear response analysis was conducted at Chiyoda-ohashi damaged by Tokachioki Earthquake in 2003. It was found that this computer program could simulate the behaviors of these damaged bridge piers with enough accuracy. The comparison of response behavior of the same bridge piers using different types of earthquake (off-shore type and inland type) was also conducted. It was found that the response caused by the earthquake of off-shore type was larger than that caused by the earthquake of inland type, because natural period of Chiyoda-ohashi is comparatively long.(3)The nonlinear response analysis of the bridges with long natural period was conducted using the earthquake ground motions simulated to huge earthquakes of off-shore type dominated by long periodic wave. It was found that large response of bridge piers occurred when the natural period of bridge is close to the natural period of earthquake.

本研究的目的是利用长周期波主导的近海型特大地震模拟地震动，对长自然周期混凝土结构进行动力响应分析，并对其抗震性能进行评价。本研究得到以下结果：(1)利用EMPR模拟技术，对工程基岩上表面的非平稳强运动时程进行了模拟，得到了2003年多千木地震和其他以长周期波为主的近海型特大地震的地震波。(2)对2003年多七木地震破坏的千代田大桥进行了非线性响应分析。结果表明，该程序能较准确地模拟这些受损桥墩的受力情况。对同一桥墩在不同类型地震（近海型和内陆型）作用下的响应行为进行了比较。研究发现，由于千代田桥的自然周期较长，近海型地震引起的地震响应大于内陆型地震引起的地震响应。(3)利用长周期波为主的近海型特大地震模拟地震动，进行了长自然周期桥梁的非线性响应分析。研究发现，当桥梁自然周期接近地震自然周期时，桥墩反应较大。
