The tapering columns and graceful arch ribs that appeared dangerously delicate were, in fact, later shown by seismic analysis to be vulnerable to damage or collapse during an earthquake. Owing to the complexity of the structure , a number of computer models had to be developed .A standard linear elastic model of the entire bridge portrayed the global seismic behavior. This model was sequentially “softened” to reflect damage occurring to horizontal strut members.The final result was a more realistic picture of the earthquake-induced displacements and forces.
In addition,nonlinear pushover analyses of the column bents and arch ribs were used to define the failure limits of these critical members.As suspected,the computer models showed that the main arch ribs were highly vulnerable to collapse during a major earthquake.Spanning more than 320 ft(98m)horizontally,each arch rib is 4.5 ft (1.8m)wide and varies in height from 8.75 ft(2.67m) at the base to ft (2m) at the crown.Each rib ris

缩减栏目和优美细腻拱肋出现危险的,事实上 分析显示,地震后受到损坏或倒塌地震期间. 由于复杂的结构, 若干型号的计算机已被开发. 标准线弹性模型描绘了整个大桥 全球抗震性能 这个模型反映损害顺序软化横向杆一般成员最终结果是比较现实的图画 <地震致位移和力量.
另外,非线性和弹塑性分析专栏排架拱肋被用来确定这些限度的失败 关键成员. 由于怀疑,计算机模型显示,主拱肋极易被大地震期间倒塌. 横跨320多尺(分所)从横向看,每一拱肋为4.5尺(1.8米)、宽8.75尺,从不同的高度(2.67m)在 基地尺(2米)在皇冠. 每一肋骨上涨120尺(87m)从其壶点飞奔50fu(砂)以上流域below.the重量每肋骨、专属 它的栏目和甲板支援,约万磅(907200公斤). 如果遭到震级为7.0级的地震, 支柱的纽带和拱肋会毁掉布带扣将根据自身重量.
