Estimate load capacity of coupler-type steel scaffolds.
Estimate load capacity of coupler-type steel scaffolds.: computes and outputs results from the input parameters.
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Permanent load | NG = tube self-weight × length + decking/kickboard/net as line load (≈0.3–0.5 kN/m per lift) | JGJ 130-2011 Technical Code for Safety of Frame Tubular Steel Scaffolding |
| Live load | Structural 3.0 kN/m², finishing 2.0 kN/m², not reduced within one bay | JGJ 130-2011 Table 4.2.2 |
| Axial force combination | N = 1.2×NG1K×H + 1.2×NG2K + 1.4×ΣNQK | JGJ 130-2011 Clause 5.2.6 |
| Capacity limit | Upright capacity [N] = φ·A·f ≈ 30–40 kN (sensitive to slenderness and wall thickness) | JGJ 130-2011 Section 5.2 |
按立杆间距与步距粗算单杆容许荷载，辅助搭设前初核；正式方案须由持证人员按规范设计。
