The proposed bridge crosses a deep and wide river valley which will become a part of a large reservoir after a hydroelectric dam is constructed. A rare extreme landslide event could occur and generate fast-moving waves in the reservoir impinging large forces on the bridge. To investigate the wave impact loadings on the bridge, three-dimensional Computational Fluid Dynamics (CFD) modeling of wave propagations were completed by hydrotechnical specialists, which were then used to analyze the structural dynamic response and to obtain force and displacement demands for structural design via a time- stepping analysis of the bridge structure. The innovative design included the use of non-uniform single circular-shaped pier columns supported on a hexagon-shaped pile cap with axisymmetrically configured rock-socketed steel pipe piles to address directional uncertainty associated with LGW. The bridge is currently under construction.","PeriodicalId":168532,"journal":{"name":"IABSE Symposium, Prague 2022: Challenges for Existing and Oncoming Structures","volume":"28 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":"129330076","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}

Due to the circumstance, that every infrastructure project is unique and dependent on local conditions the optimization of single structural elements is not that common in the field of reinforced concrete structures. When it comes to building tunnel structures using a tunnel boring machine (TBM), a lot of almost identical tunnel segments called tubbings are needed. Already a reduction of a few centimeters of the tunnel segment thickness, leads to a significant saving of concrete when it comes to tunnel structures with a length of a few kilometers. The thickness of the tunnel segments mostly depends on the design of the radial joints of the individual tunnel segments. That is why the Institute of Structural Engineering of the TU Wien developed a new reinforcement concept for tunnel segments which increases the load bearing capacity of the radial joints significantly. With a patent application submitted, tunnel segments with the new reinforcement concept were manufactured, tested and it was shown that the TU Wien proposal significantly improves the load bearing capacity of tunnel segments.Due to a presented design approach for determining the load bearing capacity of the segments and a first simplified quantification of the resource saving potential it can be said that the newly developed joint design is a great possibility for constructing tunnels with thinner tunnel segments.","PeriodicalId":168532,"journal":{"name":"IABSE Symposium, Prague 2022: Challenges for Existing and Oncoming Structures","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":"130407184","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}

A strain-driven algorithm, coupled with a bracketing approach by means of combining Bisection and Newton method has been developed. The solution of the nonlinear equilibrium equations is controlled at the strains level enforcing in the same time the elasto-plastic equilibrium for a prescribed axial force and bending-moments ratio. The ultimate (maximum) strength capacity is formulated as a problem of unconstrained mathematical optimization whereas the proposed approach evaluates the nominal strength capacity by means of using a strain-driven algorithm coupled with a bracketing approach. Since the Jacobian’s of the resulted nonlinear system of equations is non-singular global convergence may be achieved and the convergence stability is not sensitive to the initial/starting values of the iterative process and to the strain softening exhibited by the concrete in compression. The developed procedure has been used to predict the bending moment capacity diagrams of a composite cross-section with arbitrary shape. The comparisons made prove the effectiveness and the reliability of the proposed method of analysis and also for the cases analyzed here significant higher ultimate strength than nominal strength capacities of cross-section has been identified.","PeriodicalId":168532,"journal":{"name":"IABSE Symposium, Prague 2022: Challenges for Existing and Oncoming Structures","volume":"59 3 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":"129541739","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}
