5 Bridge Impairments Recorded from the not Long Ago Past
The news on structures failing are common to the current world. The failing in structural integrity ranges from huge structures to small or about simple structures. The destruction from such scenarios vary depending on the nature or degree of raging cause or the magnitude of the property. An example of those structures include the bridges. Bridges can fail when hit by an earthquake of intensity higher than what was designed for. Hefty ice accumulation in Iceland can impair the structural components of a bridge, thus the probable ice load need to be factored in while designing a bridge structures in those areas. It will demand the utility of those strong materials to put up capable bridges in those regions receiving strong destructive winds. Certain bridges can only support up to a certain loads without failing, users must observe those confines. Bridge expansion and/or unexpected loads during repairs may result in unbalanced load which can be detrimental. So bridge design should be carried out by a pro or at least under supervision of practiced fellows. Many bridge users are not perceptive to the amount of weight a bridge can carry without failing. Very few will look at the details of load a bridge can carry, many just generalize which is risky. Cases of bridges collapsing are rare, but still some large bridges have been reported to fail. The following are examples of bridges that were ravaged by different elements.
In 2017, The Central Italy Bridge went down. There was a transitory traffic after a flyover was closed off which led to setting up of the bridge to maintain the traffic link. The collapse affected the road while causing death of two people. Construction was in progress and may have impacted negatively on the supports of the bridge. There are more occurrences of bridge failures which can be attributed to load imbalance during construction. Another instance was The Bridge crossing over River Savala which caused death to a citizen in 2018. Some two trucks were crossing over when the bridge went down.
The blight of The North Bengal Bridge, Siliguri, in 2018. Carelessness of the bridge users in adhering to load requirements is what led to the plight. It was a requirement that loaded trucks should not use the bridge but most drivers did not heed the call. The bridge thereof collapsed when a heavy-duty truck tried to cross over. This happened just 3 days after another bridge collapse occurrence, which hurt the driver.
There was another bridge collapse in Genoa Italy, 2018. There are allegations that the disaster was caused by torrent rain accompanied by lightning which struck the bridge down. The bridge broke and landed on the streets killing 37 people.
