Often times we hear incidents of structural failures in infrastructures. Starting with elemental structures to those vast infrastructures and about any other structures, structural weakening is bound to happen. The destruction from such scenarios vary depending on the nature or degree of raging cause or the magnitude of the property. A bridge is an instance of such structures. Bridges can fail when hit by an earthquake of intensity higher than what was designed for. Those areas experiencing heavy ice deposit require ice load consideration when carrying out bridge design or else unexpected ice deposit may outdo the capability of a bridge. It will demand the utility of those strong materials to put up capable bridges in those regions receiving strong destructive winds. There are extremities that should not be surpassed when loads to be supported is being considered. Unsteadiness can be realized when undertaking some bridge fixations or when some bridge enlargements are being executed. 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. 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. You may this site
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. The truck driver which was got up with the incident failed to pay attention to load requirements according to the design. The bridge failed when a truck driver attempted to pass through. The driver was injured, and this was not long after another collapse case.
In 2018, there was also another bridge collapse in Genoa. The witnesses seemed to believe that the bridge fallout was due to a deluge from the sky where lightning struck the bridge severely. The bridge broke and landed on the streets killing 37 people. Check out this page here now.
