As a result, a database, and a possible practical guide on the load-bearing capacity of different combinations of old concretes, surface treatments, supplementary concrete layers, and bonding conditions will be developed. This paper will present the initial findings from this research project.","PeriodicalId":162435,"journal":{"name":"IABSE Congress, Ghent 2021: Structural Engineering for Future Societal Needs","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115021693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the face of the climate emergency, designers have been tasked with driving down the upfront emissions of the built environment. Naturally the embodied carbon characteristics of all materials have been put under the microscope and those with high impacts are being demonised, primary steel is one of those. So how does a designer balance the immediate needs of the climate emergency with the future needs of society? When confronted with a material like steel with practically perfect circularity characteristics but high embodied impacts how do designers balance the needs of today with those of tomorrow? What if steel could be made with zero carbon emissions? Coupled with its high potential for re-use and its high recycling rates is steel a friend and ally in the face of the climate emergency rather than a foe?","PeriodicalId":162435,"journal":{"name":"IABSE Congress, Ghent 2021: Structural Engineering for Future Societal Needs","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116046405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies have shown that a significant portion of embodied emissions within the built environment are due to structural materials. However, many structural engineers are, not only uneducated in the concept of embodied carbon, but also not aware of the role their decisions can make in addressing climate change. This is further exacerbated by a profession that does not have sufficient structural system embodied carbon benchmark information to make important and informed early design decisions. This required the collaborative development of a structural engineering commitment program, SE 2050, that is supported by leading professional organizations to spur the education and transformation of the profession.","PeriodicalId":162435,"journal":{"name":"IABSE Congress, Ghent 2021: Structural Engineering for Future Societal Needs","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124658718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The punching capacity was studied in a previous series of experiments, showing a higher capacity thanks to compressive membrane action in the deck. Then, concerns were raised with regard to fatigue loading. To address this, two series of large-scale experiments were carried out, varying the number of loads (single wheel print versus double wheel print), the loading sequence (constant amplitude versus variable amplitude, and different loading sequences for variable amplitude), and the distance between the prestressing ducts. An S-N curve is developed for the assessment of slab-between-girder bridges. The experiments showed that compressive membrane actions enhances the capacity of thin transversely prestressed decks subjected to fatigue loading.","PeriodicalId":162435,"journal":{"name":"IABSE Congress, Ghent 2021: Structural Engineering for Future Societal Needs","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129433963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bridges for the Light Railways, even if their static scheme is often very simple, are peculiar structures where the interactions between vehicles, rail and bearings play a fundamental role. An important aspect of the bearings for Light Rail bridges, frequently requiring special solutions, is also the very high train frequency and the relatively high deformation of the structures under load, implying extremely high performance requirements and fatigue resistance of the bearings . In some cases, as for instance in monorail lines, also uplift forces shall be considered. The authors, currently involved in the design and supply of the structural bearings for several Light Rail projects in the world (Thailand, Egypt, Indonesia and others), describe the different solutions of the bearing systems currently utilized, putting in evidence the fatigue and wear resistance problems.","PeriodicalId":162435,"journal":{"name":"IABSE Congress, Ghent 2021: Structural Engineering for Future Societal Needs","volume":"120 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128486688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Assessing change in deflections could also simplify the assessment work for inspectors. Recent developments in digital camera technology and photogrammetry software enables point cloud with colour information (RGB values) to be generated. Thus, close range photogrammetry offers the potential of monitoring big and small-scale damages by point clouds. The current paper aims to monitor geometrical deviations in Pahtajokk Bridge, Northern Sweden, using an optical data acquisition technique. The bridge in this study is scanned two times by almost one year a part. After point cloud generation the datasets were compared to detect geometrical deviations. First scanning was carried out by both close range photogrammetry (CRP) and terrestrial laser scanning (TLS), while second scanning was performed by CRP only. Analyzing the results has shown the potential of CRP in bridge inspection.","PeriodicalId":162435,"journal":{"name":"IABSE Congress, Ghent 2021: Structural Engineering for Future Societal Needs","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130057667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet in serving important societal needs, construction has also been a major contributor to the degradation of the planet’s natural resources and acceleration of climate change. These harmful impacts are now threatening human prosperity and safety. The Henderson Colloquium, organised by IABSE UK in September 2020, asked key players across multiple sectors of the construction industry this question: How can the construction industry serve the future needs of a society threatened by climate change? The discussions revealed the need for deep-seated change across all elements of the industry including our business models, our professional institutions, education, and government policy. These outcomes are being shared in this paper to stimulate thinking in a wider, international forum of construction professionals.","PeriodicalId":162435,"journal":{"name":"IABSE Congress, Ghent 2021: Structural Engineering for Future Societal Needs","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130760043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
