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 occurrence can be ruinous basing on the rage of the causing agent or the size of the structure. An example of those structures include the bridges. A bridge may flunk is impacted on by a quake of greater degree than the one that was built 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.
Most bridges are designed to support large loads, but still there is a limit which must be observed. 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. Most people are not keen whether a bridge can support certain load or not. They trust that the bridge was engineered to support them without going for the details. Bridges falling down are not so common incidences with the increased considerations during designs, still few cases have been witnessed. Here are some instances of the latest bridges’ failures that have been reported.
In 2017, The Central Italy Bridge went down. An original flypast was closed temporarily and the bridge was built to ease the transient traffic of that time. The collapse affected the road while causing death of two people. It was reported that the bridge was under construction when its structural supports failed. 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. The load of some two trucks trying to cross over could not be sustained and the bridge was destroyed. Read more now!
In 2018, The North Bengal Bridge of Siliguri was brought down. The ignorance to supported axle load was what led to the fall. The truck driver which was got up with the incident failed to pay attention to load requirements according to the design. The bridge thereof collapsed when a heavy-duty truck tried to cross over. The driver was hurt, and that was few days after another collapse.
There was another bridge collapse in Genoa Italy, 2018. Those who witnessed the collapse reported that there was a loud cloudburst which they think was a lightning which struck the bridge. The bridge broke and landed on the streets killing 37 people. You may view here for some bridge ideas.
