Due to these two effects, piles are susceptible to damage under strong earthquakes. A complete analys needs to include the two effects described above. In this study, we are going to develop a analysis method to consider both the inertia and kinematic effects. In addition, the nonlinearity of pile material is considered. By this method, the response and damage of pile foundations under strong earthquakes can be completely evaluated for use of engineering design and earthquake damage evaluation.樁基礎慣性力效應地盤運動效應損害分析耐震設計Pile foundationsInertial effectKinematic effectDamage analysisSeismic design.高等教育深耕計畫-核心研究群計畫 【樁基礎在強震下之反應及損害分析】
