Pedestrian Bridge Substructure Reinforcement Detailing Sections

This comprehensive structural drawing set details the reinforcement specifications for a pedestrian bridge substructure, featuring various structural elements including columns, beams, foundation footings, and ramps. This drawing includes multiple cross-sectional views with detailed rebar layouts showing precise reinforcement patterns. Key reinforcement specifications include Y8-150mm stirrups, primary Y16-Y32 longitudinal bars for columns, and Y20-Y25 bars for main structural elements. The concrete grade specified is M20 with Fe500 grade reinforcement steel. All structural connections are detailed with proper development lengths (50Ø) and specified bar spacings of 125-150mm throughout. The substructure design includes specialized elements such as ramps with Y10-S8-150 reinforcement configurations, staircase components with Z-beam details, and column foundations with comprehensive reinforcement schedules. Cross-sectional details provide clear information about concrete cover requirements and reinforcement placement in critical structural joints. The drawing follows standard structural detailing conventions with bar bending schedules organized by structural element type.
