Study Notes
Assumptions
- Maximum slab depth calculated by subtracting floor-to-floor height and service zone/floor-to-ceiling height from the total height.
- Internal columns are absent in showroom and residential areas, so beams should be able to carry their own weight.
- Concrete residential walls are load-bearing.
- Glazed area weight is negligible.
- Basement level is on foundation.
Alternatives
- Post-tensioned band beams increase tensile strength but have a limited span (approximately 16m).
- Deflection and creep could be significant for long spans, particularly 36m.
- Regular monitoring and inspection are necessary to prevent large deflections and cracks in long-span slabs.
- Fabrication and construction time, cost, and complexity are disadvantages of post-tensioned systems.
- Composite truss systems are more cost-effective for longer spans and easier to manufacture.
Recommended Floor System
- Composite truss systems are better suited to larger spans than post-tensioned systems in the specified area.
- Truss beams (6m centers, running south to north and 42m long running west to east) along with external and internal columns (6m centers around the glazed area on level 2) will support the load effectively.
- Pre-tensioned slabs will be used in residential and office areas.
- 6m center reinforced concrete columns are needed for the PT slabs.
