The location of the bridge is an important tourist and pilgrimage destination with lush green surroundings and backwaters of Gosekhurd Dam. The bridge has an overall length of 705m and deck width of 15.25m to accommodate 2 lanes of vehicular traffic and 3m+3m footpath for pedestrians. The structural arrangement of the bridge comprises 2 modules, with Module 1 of 420m and Module 2 of 280m length with span arrangements of 70m+140m+140m+70m and 70m+140m+70m respectively. The superstructure is cable stayed with RCC deck ladder type with an RCC pylon height of 30m above deck level. The pylon P3 at the center of the bridge is also proposed with Viewing Gallery 40m above deck level which is structurally independent from the main bridge. The Module 1 of the bridge is constructed by cantilever method for pylon P2 and anchored span method for pylon P1 and P3. The Module 2 of the bridge is constructed on staging. This paper discusses the design and construction aspects of the bridge along with staged construction analysis. This is one of the very few cable stayed bridges in India where all 3 methods of construction of a cable stayed superstructure are adopted in the same bridge.","PeriodicalId":237396,"journal":{"name":"IABSE Symposium, Istanbul 2023: Long Span Bridges","volume":"9 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":"123795455","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}

Thus, the assessment of seismic resilience is decisive in keeping the functionality of bridge infrastructure and helping their quick recovery during strong earthquakes. This article focuses on enhancing bridge resilience by the best drift ratio estimation while considering seismic ground motion mainly attributed to the wave passage, loss of coherence, and different local soil conditions. To do this, we adopt an artificial intelligence approach. However, there are several machine-learning algorithms (MLA); and the choice came back difficult. Here, we follow the roadmap given by (Boumédiène Derras & Makhoul, 2022), which offers the best MLA suited to analyze a bridge's seismic resilience. Firstly, a dataset is created. This dataset contains the metadata (explanatory factors), such as earthquake magnitude (M), Ground-Motion Intensity Measures (IM), soil class, and parameters of structures, such as displacement ductility capacity as well as drift ratio (target). The finest model needs to characterize well the drift ratio. The value of the drift ratio, predicted in this work, gives us the bridge's performance level (PL). This PL allows the classifying of infrastructure resilience.","PeriodicalId":237396,"journal":{"name":"IABSE Symposium, Istanbul 2023: Long Span Bridges","volume":"70 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":"129168289","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}

It is an important issue for the structural design of suspension bridges. It is a problem that needs further study for high-speed and heavy-haul railway suspension bridges. There is the characteristics of heavy train live loads, high speed and high demand for running security and passenger comfort, the technical standards and so on. The paper is analysis the stiffness evaluation indexes of railway suspension bridges adopted by the codes of various countries in the world, and compares them with the regulations in China’s general bridge codes. The key technologies of the thousand-meter-scale road-rail suspension bridges for high speed for passenger trains, 120 km/h for freight trains) and heavy load are studied. Based on the research on the road-rail suspension bridge with main span of 1 196 m, the influences of different supporting systems, arrangement of auxiliary piers, ratio of height to span, ratio of width to span and ratio of vertical to span on the vertical and lateral stiffness of the bridge are analysis, and the stiffness evaluation indexes and suggested values for thousand-meter-scale road-rail suspension bridges are proposed. The proposed long-span suspension bridge scheme is technically feasible, economically reasonable, and has good horizontal and vertical stiffness, smoothness and running comfort.","PeriodicalId":237396,"journal":{"name":"IABSE Symposium, Istanbul 2023: Long Span Bridges","volume":"15 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":"117216899","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}

This paper describes the design of the substructure of the suspension bridge, which has a world record main span of 2023 m. The substructure consists of the two tower foundations, the two anchor blocks and the two side span piers.The paper describes design to achieve fast-track construction and resilient structures with optimized material quantities. For the tower foundations an innovative solution consisting of a lower cellular reinforced concrete base and an upper part consisting of two hollow composite steel shafts which extends above water level have been developed. Critical temporary construction stages, including the immersion process, ship impact, and seismic loadings, call for complex structural analysis and verification.For the anchor blocks efficient concepts have been developed to optimize quantities of concrete and excavation. At the European side this is done by taking advantage of the local soil conditions and activating the backfill on top of the anchor block as counterweight and at the Asian side anchor block an innovative concept with diaphragm panels at the bottom of the anchor block has been developed to enhance the horizontal shear resistance with the ground.For the side span piers supporting the ends of the main steel bridge deck and the concrete girders of the approach bridges soft soil and seismic forces requires deep bored concrete pile foundations with special measures for improved soil in the upper liquefiable layers.","PeriodicalId":237396,"journal":{"name":"IABSE Symposium, Istanbul 2023: Long Span Bridges","volume":"39 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":"132792067","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}
