The Korean seismic design provision was developed in 1988. In present seismic design for building is compulsory in Korea. The seismicity of Korean peninsula is between low and moderate. Basically the Korean seismic provision was developed based on Uniform Building Code and ATC 3-06 provision. One of the objectives of this research is to investigate the relationship between the seismic design method in Korean seismic provision and ISO 3010. The major parameters included in both provisions were classified and compared. They are seismic intensity, importance factor, seismic hazard zone factor, strength reduction factor, and spectral ordinates. The vertical distribution of seismic force and shear of two provisions is also investigated and compared. Based on the investigation it is concluded that the most prominent difference between these two provisions is the limit states under consideration. In ISO 3010 two limit states are explicitly considered which are for serviceability and ultimate. … More In Korean provision one limit state is considered which is ultimate limit state. However, the provision in progress of revision considers two limit states for operation and collapse prevention.The Korea Ministry of Construction and Transportation and The Earthquake Engineering Society of Korea established a new guideline for performance-based seismic design in 1997. In the guideline the seismic coefficients for construction of the design spectrum were provided for double performance levels, functional and collapse prevention performance levels, and for earthquakes with various recurrence periods. In this study a steel framed structure was designed in accordance with the conventional single-level seismic design code, and was analyzed using capacity spectrum method to evaluate the nonlinear performance of the structure subjected to the strong earthquake load corresponding to the collapse prevention performance objective. The maximum inter-story drift was compared with the performance criteria specified in the new guideline to check whether the building structure designed in accordance with the conventional design code satisfy the performance criteria recommended by the new performance-based seismic design guideline. It was found that the model structure, although designed for the conventional single level earthquake load, retains enough margin for safety for the earthquake load of 2,400 year return period (earthquake level for collapse prevention performance objective). It was also found that for the given model structure the results from the capacity spectrum method generally coincide well with those obtained from the time history analysis. Less

韩国抗震设计规定于 1988 年制定。目前，韩国的建筑抗震设计是强制性的。朝鲜半岛地震活动处于低度和中度之间。韩国的抗震规定基本上是根据统一建筑规范和 ATC 3-06 规定制定的。本研究的目的之一是调查韩国抗震规定中的抗震设计方法与 ISO 3010 之间的关系。对两个规定中包含的主要参数进行了分类和比较。它们是地震烈度、重要性因子、地震危险区因子、强度折减因子和谱坐标。还对两种规定的地震力和剪力的垂直分布进行了调查和比较。根据调查得出的结论是，这两项规定之间最显着的区别是所考虑的限制状态。在 ISO 3010 中，明确考虑了两个极限状态，即适用性和极限状态。 … 更多 在韩国规定中，一种极限状态被认为是最终极限状态。然而，正在修订的规定考虑了运行和防倒塌的两个极限状态。韩国建设交通部和韩国地震工程学会于1997年制定了新的基于性能的抗震设计指南。指南中提供了双性能水平、功能水平和防倒塌性能水平以及不同复发周期地震的设计谱构建的抗震系数。本研究按照常规单级抗震设计规范对钢框架结构进行设计，并采用能力谱法进行分析，评价结构在强震荷载作用下的非线性性能，对应防倒塌性能目标。将最大层间位移与新导则规定的性能标准进行比较，以检查按照常规设计规范设计的建筑结构是否满足新的基于性能的抗震设计导则推荐的性能标准。结果发现，模型结构虽然是针对常规单级地震荷载设计的，但对于2400年重现期的地震荷载（防倒塌性能目标的地震级别）保留了足够的安全裕度。研究还发现，对于给定的模型结构，容量谱方法的结果通常与时程分析获得的结果非常吻合。较少的
