在断裂以北6日码头,这是显示所有的加固板损坏由于超载和疲劳裂纹在1 – 35大桥。这种形式的损害最终直接对解理断裂的类型。断裂的模式在衣袖上的图从盘子。也注意到结构变形的调查人员也由于损失引起的结构支撑1 – 35的时候崩溃。发生这种情况是因为超载的连锁反应通过张力或压缩,因此这导致骨折。中间跨的南部地区造成的损害损害的相同的过程中间跨度北部部分南面的7号码头(萨勃拉曼尼亚,2008)。也发现了一个节点位置或网站也遇到破损的护翼型板块相互链接的所有结构成员因为过载和破损的桥。这种形式的骨折发生因为压缩或拉伸形成的压力。总分离1 – 35大桥中间跨度是由于这些类型的骨折,允许或者强迫桥不利陷入河里。1 – 35大桥的其他部分也崩溃了,因为整个失踪的这段桥(大厅,2008)。

In the area of fracture which was just north of the 6th pier, it was revealed that all the gusset plates which were damaged because of the overload and fatigue cracking on the I-35W Bridge. This form of the damage ultimately direct towards to a fracture of cleavage type. The pattern of fracture is given in the figure from on the gusset plates. It is also noticed by the investigators that the structural deformation was also caused due to the loss of structural support at the time of the I-35W collapsed. This happened because of the overloading chain reaction either by tension or compression; therefore this caused number of fractures. The damage of middle span’s southern portion caused a same process of damage in the middle span’s northern portion just south of the 7th pier (Subramanian, 2008). It is also identified that a node at this position or site also encountered breakage in all of the gussets type plates that linked all the structural members with each other because of the overload and breakage in the bridge. This form of fracture took place because of compressive or tensile form of stress. Total separation of the I-35W Bridge middle span was caused due to these types of fractures, permitting or forcing the bridge to fall adversely into the river. Other parts of the I-35W Bridge also collapsed because of entire missing of this segment of bridge (Hall, 2008).
