All the design handbooks of civil structures of rapid transit systems in Taipei city and Kaoshung city adopt the 1984 under- structure design code of SCRTD in south California and METRO in Los Angeles, however the considerations of related details in the code are not cautious, for instance, the design of lateral steel bars considers temperature effect but ignores maximum axial force, shear force, bending moment and so on.The geographical positions of Japan and Taiwan are similar to each other under the fact that they are in the around-Pacific seismic belt and earthquakes occur frequently in this area. According to the statistical data about earthquake, there are ten great quakes happened this century. Among these ten quakes, there are seven quakes occurred in Japan especially the KwanDon causes heavy casualty which 140 thousands people perished in this event occurred on Sep. 1st, 1923. As the saying is "Practice makes perfect", the art of earthquake resistance design of Japan has the saving grace of experience.Consequently the new earthquake resistance design method is taken to be a comparison. It can be found that has the contents of Japan code consider sedulously. Besides that, the geographical, geological and seismic conditions of Japan are similar to our country in which the earthquake resistance code of roads and bridges published by Dept. of Transportation in 1995 was came from Japan code. Therefore, the understanding of the spirit of Japan code is necessary.
