“The preferred method for building bridges today is that there is redundancy built in,” Jennifer Homendy, chair of the National Transportation Safety Board, which is leading the investigation into the collapse, said at a press conference Wednesday evening. “This bridge did not have redundancy.”
More redundancies would allow the bridge to be insulated from a failure in one section leading to failures in other sections, engineers said.
The Key Bridge was one of only 17,000 bridges in the country, about 3%, characterized as having a “fracture critical” design, meaning if one portion sustained enough damage, the entire structure would collapse.

我老第一时间就指出这个是设计缺陷,广州那桥就可以只断一截其他完好

这桥墩被撞
相当于踢足球被飞铲
什么样的桥能顶得住
