Hydrological and Structural Design of a T-Girder Motorable Bridge Over Seti Khola

  • Unique Paper ID: 187007
  • PageNo: 6152-6156
  • Abstract:
  • This detailed project report discusses hydrological design concerns and structural analysis for a motorable bridge. Beginning with a detailed assessment of the watershed and an estimate of design floods, topographic data obtained from the topographic survey and DHM Pokhara offices informs the selection of relevant hydrological methodologies. The research includes in-depth analyses of rainfall, topography, and land use to determine runoff volumes and peak flow rates. The report uses approaches such as the Rational Method, DHM Method, and WECS Method to compute the High Flood Level for design flood through stage-discharge curve analysis. Moving on to the structural element, the project completes a thorough limit state design of an RC T-beam bridge in accordance with Nepal Bridge Standards, Department of Road, Indian Standards, and Indian Roads Congress guidelines. The superstructure, bearing, substructure, and foundation components designed utilizing limit-state design concepts. The superstructure components are investigated under Class 70R Wheel, Class 70R Tracked, Single axle load, Bogie load, and Class A loading conditions, using plate bending theory for slabs and Courbon's approach for major girders. The limit state method is used while selecting and designing elastomeric bearings. The substructure design features two similar abutments and an open foundation to accommodate both basic and seismic load combinations. In addition, a stability study of the abutments is performed for specific load scenarios. The result of this effort is drawings and bar bending schedules and design of an RC T-Beam Bridge that incorporates many engineering disciplines and standards.
