Structural Analysis & Warnings

Long Span Warning

Span exceeds 8m. Consider deeper beams, post-tensioned slabs, or adding intermediate columns to limit deflection.

High-Rise Column Warning

For buildings above 8 floors, columns should typically be at least 500x500 mm to support gravity loads and resist lateral wind loads safely.

Grid Aspect Ratio Notice

Grid ratio X/Y or Y/X exceeds 2.0. This behaves as a one-way slab system, where beams in the short direction carry significantly more loads.

Low Roof Clearance Notice

Roof clearance is too low (< 6.0m). Standard pickleball play requires a minimum clear height of 6.0 meters to prevent game balls from hitting the overhead structure.

Clear Span Too Narrow

Span is too narrow (< 9.0m). A standard pickleball court playing area (including out-of-bounds safety margins) requires at least 9.0 meters of column-free clear width.

Structural Steel Recommended

For pickleball court covers or large sports halls, lightweight structural steel roof trusses are highly recommended to provide column-free clear spans economically compared to heavy reinforced concrete.

Multi-Story Court Notice

Sports court canopies are typically single-story structures. Multi-story court frames require significantly heavier structural framing and analysis.

Preliminary Design Rules Used

Concrete Beam Depth: L / 12 - L / 15 (width is 1/2 to 2/3 of depth)
Steel Beam Depth: L / 18 - L / 22
Concrete Column Size: (Floors * 50) + 200 mm
Steel Column Size: (Floors * 30) + 150 mm

Engineering Notice

This tool provides preliminary estimates only. Final structural design must be verified by a qualified and licensed structural engineer.

⚠️ Preliminary Safety Analysis

✅ All values fall within standard typical parameters for preliminary sizing.

Warning: Long Span (> 8.0m) - Span exceeds 8m. Deflection control governs. Consider post-tensioning or adjusting layout.

Warning: High Rise (Floors > 8) - Building exceeds 8 floors. Column sizes may need wind/seismic verification.

Notice: High Grid Mismatch (Ratio > 2.0) - Grid aspect ratio exceeds 2.0. One-way slab load path dominates; short direction beams carry major floor loads.

Warning: Low Clearance (< 6.0m) - Standard play requires a minimum clear height of 6.0m to prevent game balls from hitting the ceiling.

Warning: Span Too Narrow (< 9.0m) - A standard court envelope requires at least 9.0m clear width.

Recommendation: Use Structural Steel - Large canopy covers are optimized using lightweight structural steel trusses rather than concrete.

Warning: Multi-Story Court Cover - Canopies are typically single-story structures.
