It is well known that the occurrence possibility of huge earthquakes along the Nankai oceanic trench, specially in Tokai region, is extremely high. A large variety of disaster-prevention measures have been applied for various types of structures and. However, the effect of strong motion duration on structural damage, specially progressive damage, has not been investigated and taken into account for earthquake-resistant design.The research has been intended for the Tokai region and the Tonankai-Tokai coupled earthquake was selected as the hypothetical huge earthquake.Major results of the research project may be summarized as in the following.(1) the effect of strong motion duration on the damage of river levee due to soil liquefaction(2) countermeasures against liquefaction-induced large settlement of river levee(3) the effect of strong motion duration on seismic damage of reinforced concrete structures(4) rapid estimation on seismic intensity distribution on the basis of inversion for huge earthquakes

众所周知，南海海沟沿着，特别是东海地区发生大地震的可能性极大。各种各样的防灾措施已被应用于各种类型的建筑物和。然而，强震持续时间对结构损伤，特别是渐进损伤的影响，在抗震设计中还没有得到研究和考虑。本研究以东海地区为研究对象，以东海-东海耦合地震为假想大地震。(1)强震持续时间对堤防液化破坏的影响（2）堤防液化大沉降对策（3）强震持续时间对钢筋混凝土结构地震破坏的影响（4）基于大震反演的地震烈度分布快速估计
