{"title":"Reliability-based Fire Protection of Structural Cables due to Deck Fires on Cable Supported Bridges","authors":"P. Kotsovinos, Y. Panev, Heikki Lilja, Atte Mikkonen, Alberto Carlucci, P. Woodburn","doi":"10.1080/10168664.2023.2213257","DOIUrl":"https://doi.org/10.1080/10168664.2023.2213257","url":null,"abstract":"Abstract Cable supported bridges are typically part of community-critical infrastructure and therefore the consequences arising from extensive structural damage due to a fire and the subsequent operational discontinuity could be significant beyond the damage to the bridge itself and the cost of repairs. Bridge design standards generally do not provide guidance and hence fire resistance requirements are often informed by first principles assessments of the thermal and structural response of the structure to proposed fire scenarios. A deterministic assessment can provide a reasonable worst-case scenario but it does not allow bridge stakeholders to make informed decisions with regards to uncertainty and the low likelihood of fires occurring to identify the benefits of investments in structural fire protection. This is because the target reliability required for each bridge may be different depending on its characteristics, and the expected fire severity has a probabilistic nature. This research aims to fill this gap by undertaking a reliability-based analysis to assess the probability of structural failure by considering the probability of a fire of a given size occurring and the uncertainty in the incident location and wind. The methodology is demonstrated through the case study of an operational 450 m long cable supported bridge section and a fire scenario based on a liquid fuel tanker. Liquid tankers can result into two type of fire scenario: first, a fire being contained within the tanker; and secondly, a fire due to a pool on the deck. Both fire scenarios have been characterised and it was determined that the contained tanker scenario presents a more onerous design case owing to its more prolonged duration. A Monte Carlo analysis was undertaken for a total of 10,000 independent trials of the combination of the location of the fire and the wind direction. The frequency of the fire was also examined to establish the probability of structural failure of a cable. It was established that the inclusion of wind can sometimes reduce the estimated height at which cables may experience temperatures with the potential to cause cable failure. However, for a number of the cases, the estimated height can remain broadly similar (i.e. within a couple metres difference) to the worst-case calculated value. Based on this analysis, the influence of the required level of reliability as well the fire protection duration specification agreed with bridge stakeholders can be used to determine the height at which cable fire protection is necessary to reduce the probability of structural failure to a level acceptable to the stakeholders. This approach allows bridge designers and stakeholders to make informed decisions with regards to provision and extent of fire preventive/protective measures for cable supported bridges.","PeriodicalId":51281,"journal":{"name":"Structural Engineering International","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47987419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This load configuration can induce buckling instability. The problem of shear buckling instability in such applications has so far received very little attention from researchers owing to the additional analytical difficulties involved in obtaining rigorous solutions to the buckling of plates when subjected to partial loadings, and the present research aims to address the problem and present a rigorous solution. It focuses on investigating the problem of linear and nonlinear buckling of simply supported thin plates subjected to local in-plane shearing using the finite element method. The critical shear buckling stress is determined for different load cases applied to a judiciously designed plate specimen. Compressive, shear and von Mises stress analyses are conducted. The results achieved are summarized as tables, graphs and iso-stress contours. It is shown that the stability effect of the load ratio on the specimen is reached when the load extent covers 55% of the plate sides. The plate buckling in the length direction is justified by significant compressive stresses recorded in this direction. It has been found that, at buckling, a compressive diagonal field action occurs. Finally, the von Mises analysis shows that plasticization occurs at the plate length loading stop points.","PeriodicalId":51281,"journal":{"name":"Structural Engineering International","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45260547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
