G+4 Mixed-Use RC Structure Beam and Column Detail Section Plan

This structural drawing illustrates comprehensive reinforcement details for a G+4 mixed-use building with basement parking. The plan showcases RC column sections (C1-C7) with varying reinforcement configurations (ranging from 8d14 to 14d20) and stirrup spacing at 180mm. Features include a parking ramp with 3.5% slope, 200mm thick RC slabs with d8@150mm and d12@110mm reinforcement patterns. The staircase detail indicates 20 risers (175mm height) with 300mm treads. Concrete specifications call for C-25 grade for beams, C-5 for lean concrete, with S300 grade steel for bars <Ø10 and S400 for ≥Ø12. Beam sections (200x350mm) show 3d16 continuous reinforcement. Columns provide clear cover of 25mm, while footings maintain 50mm cover. The drawing incorporates both grid-based structural framing and foundation-to-roof detailed sections with elevations ranging from -5.56m (basement) to +21.75m (roof level).
