Plinth Beam PB1 Section Detail With 225mm Brick Wall And PCC Base

This plinth beam PB1 section detail drawing illustrates the structural arrangement of a reinforced concrete plinth beam supporting a 225mm thick brick wall. The section drawing shows the plinth beam positioned above the ground level with proper reinforcement configuration and foundation support. The beam section includes 2 bars of 12mm diameter reinforcement and an additional 2 bars of 20mm diameter reinforcement placed within the beam section to provide structural strength. Stirrups of 10mm diameter are arranged at 100mm spacing near supports and 200mm spacing at mid span to maintain structural stability. The plinth beam width is approximately 225mm, and the beam depth is about 450mm measured from the finished floor level. The drawing also shows the brick wall alignment directly above the beam, which distributes wall load evenly to the foundation.
