唉，美国5号高速桥梁崩塌

[Adenine]

水泥建筑只有40年左右的稳定期，其后强度下降很快。

是不是那些几十层高的建筑，过了40年倒塌的危险就大大增加？

搜下面几座桥：
酒泉红水河铁桥
汶水桥
武汉长江大桥

这桥先天性不足。

 

[dsss]

也是超重惹的祸？

天朝那点糗事，你怎么总拿出来填堵？

 

[lilidoo]

赵州桥不是还好着吗？

 

[暖雨疏]

70年后强度下降到原初50%左右（30年前的资料）。

It was an Edmonton-area truck driver who struck part of a bridge in Washington State Thursday evening, causing the bridge to collapse and sending two vehicles into the river below, police confirmed on Friday.
No one was killed in the disaster, though three people were taken to hospital for treatment of their injuries. All three have now been released.
Sgt. Kirk Rudeen, of the Washington State Patrol, said William Scott, a 41-year-old resident of Spruce Grove, Alta., was at the wheel of a semi-truck carrying a large load of steel when he struck one of the bridge's girders.
