In addition, the risk grade obtained by the proposed framework can serve as a reference for anti-explosion design. ![]() The proposed framework can assess the risk grade of various hazards, and assessment results can be used for guiding the structural design considering the blast risk. In order to verify the rationality of the proposed framework, the risk grades of cases from other related studies are evaluated by the proposed method, and the obtained results are consistent with the previously reported results. June 21 25, 2022. The attributes of the risk parameter are ranked, and the membership function of linguistic terms is calculated in the assessment process. The proposed framework is illustrated by evaluating the risk grade of seven bridges on a route. Meanwhile, weight vectors of attributes are determined by the entropy coefficient method. Using the proposed framework, a hierarchical structure for risk assessment of blast hazard on bridges is established, and the risk function is defined. Basic information about bridges is transformed into fuzzy numbers in the conversion system, and the risk grade is calculated by the aggregation progress. The proposed framework consists of a conversion system and aggregation process. This paper proposes a fuzzy-based framework for assessing the impact of blast incidents caused by dangerous goods on bridges. However, the studies on the blast risk assessment of bridges have been limited. President Putin is to hold a meeting of the Russian Security Council on Monday, in what the Kremlin says is a planned event.Explosion of dangerous goods or a vehicle bomb can cause severe damages to bridge structures accompanied by serious casualties and significant economic losses. The bridge is a vital artery in Moscow’s supply chain to the battlefront in its invasion of Ukraine and to the annexed Crimean territory itself. Speaking on Sunday, the Moscow-appointed governor of Crimea, Sergei Aksyonov, said rail traffic would continue as normal but the surviving roadway would for now take only light vehicles, while Lorries and buses would be transported by ferry, he added. Russian authorities moved swiftly to reopen those parts of the key crossing still intact and said late on Saturday that the bridge had been partially reopened to road and rail traffic. Reducing vulnerability and creating a resilience transportation system has. President Volodymyr Zelensky acknowledged the incident in his nightly address on Saturday, saying: “Today was not a bad day and mostly sunny on our state’s territory. Transportation systems are integral to a communitys growth and development. Ukrainian officials responded with thinly veiled approval to the explosion but have not indicated that their forces were behind the attack. Since the bridge plays a strategic role in the war, Ukrainian authorities have said it is a legitimate target, as they vow to retake the peninsula. ![]() Hailed by Russian media as “the construction of the century”, the bridge has been crucial to Russia for the movement of military equipment, ammunition and troops into southern Ukraine. Video shared on social media showed a long queue of vehicles at the bridge to leave Crimea towards Russia on Sunday. Russian Deputy Prime Minister, Marat Khusnullin ordered the destroyed parts of the bridge to be taken down and said divers would begin investigating damage below the waterline on Sunday morning. Officials said work to fix the damaged sections would begin immediately. The bridge is also a pivotal symbol of Russia’s annexation of Crimea from Ukraine in 2014 where the blast killed three persons, Russian investigators said. President Vladimir Putin has now ordered the country’s Federal Security Service (FSB) to oversee the key crossing to the occupied peninsula. Russia ramped up security on its only bridge to Crimea after a huge blast destroyed sections of it on Saturday.
