简介:这份报纸为在近差错的区域构造地震设计系列论述方法论。由分析近差错的脉搏类型地面运动的特征,一个相等的脉搏模型被建议,它能很好代表特征近差错前面择向性并且抛步脉搏类型地面运动。为近差错的区域的规范的水平地震设计系列用记录近差错的脉搏类型地面运动被介绍,相等的脉搏类型扎根了运动,它基于结合的相等的脉搏模型被导出地面运动参数变细关系。为近差错的区域的规范的垂直地震设计系列被与vertical-to-horizontal加速放大相应水平系列获得光谱近差错的脉搏类型的比率扎根了运动。建议地震设计系列看起来在统计意义有相对小的分散。为水平、垂直的方向的地震设计系列能提供选择光谱为地震设计代码的形状。
