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。

简介:和开发的迪拜唯一的率,在统一阿拉伯人酋长(UAE)的本地设计和构造惯例保证特殊注意到侧面的抵抗力量的系统(LFRS)的选择。这研究为高大楼为LFRS的选择建议四个不同可行答案并且确定地震性能和费用上的这些选择的影响。考虑的系统是:钢特殊抵抗时刻的框架(SMRF),具体SMRF,钢双系统(有特殊的钢盘子的SMRF砍墙,SPSW),并且具体双系统(有特殊水泥的SMRF砍墙,SCSW)。LFRS选择被地震安装以及采用的设计和构造惯例在迪拜驾驶。具体设计选择是,这被发现一致地不比他们的钢对应物昂贵。钢双系统被期望基于它的相对更小的interstory飘移有最少的损坏。然而,这比较喜欢的表演以更高起始的构造成本来。相反地,钢SMRF系统被期望有大多数损坏并且由于它的过多的灵活性联系了修理费用。二种具体选择被期望除了他们的更小的起始的构造费用有相对中等的损坏和修理费用。
