Main results obtained in this study are as follows :1. As for the inelastic response spectra relating to the seismic design methods :(1) Average acceleration response spectrum for every twelve acceleration wave differ widely among the Level 2 simulated earthquake motion specified in the Japanese Specification, the one satisfying attenuation relationship of maximum ground motions and recorded earthquake motion in Hyougoken Nanbu Earthquake.(2) Difference in the earthquake Type, soil Group, characteristics of SDOF system (restoring force model, ultimate ductility, plastic rigidity, etc.), required value Dr of modified Park-Ang's damage index and positive coefficient β in the index affects value and shape of the (mean+ σ) inelastic response spectra for every twelve Level 2 simulated earthquake motion specified in the Japanese Specification.(3) Consequently, it is essential to pay enough attention to the difference in the (2) above when we derive the inelastic response spectra for seismic design.2. As for the seismic design method :(1) Three design methods, that is, 1) force-displacement-based design method, 2) displacement-based one and force-based one are developed by the use of inelastic acceleration-displacement response spectrum, displacement spectrum and appropriate seismic force and acceleration spectrum, respectively.(2) Design result of the methods 1) and 2) for road bridge-RC piers on the Group II soil and subjected to Type II earthquake motion, requires larger value of ultimate ductility than that of the method 3) and ductility design method in Japanese Specification. This result means that the former methods 1) and 2) taking account of displacement response spectrum in the design criteria become safer method than the latter ones.(3) Design earthquake force calculated obtained from inelastic acceleration spectrum shows larger value than that of the ductility design method, based on energy constant law.

在本研究中获得的主要结果如下：1。至于对地震设计方法的非弹性响应：（1）在每二十二个加速度波的平均值之间的平均响应频谱之间的平均值在2级2级模拟地震运动中差异很大，一种令人满意的衰减，在hyougoken nanbu中记录了地震类型的差异。索引中的索引和正系数β在每个十二级2级模拟地上的地震运动中都会关注（2）中的差异（2），这会影响（平均+σ）IC响应光谱的价值和形状。上面是地震设计的响应光谱。2。弹性的NT响应频谱，DS的设计结果。在设计标准中的位移频谱比后者的Quake力量相比，从非弹性加速度频谱中获得的地震力显示出基于能量恒定法的更大值。
