Structural glass panel — sizing under wind, thermal, and self-weight loads.

Covers monolithic, laminated, and insulating glass units (IGU).

Fields

width: f64

Panel width (m).

height: f64

Panel height (m).

thickness: f64

Total glass thickness (m) — sum of all plies.

e_glass: f64

Young’s modulus of glass (Pa) — typically 70 GPa.

nu_glass: f64

Poisson’s ratio of glass — typically 0.23.

density: f64

Density of glass (kg/m³) — typically 2500.

wind_pressure: f64

Design wind pressure (Pa) — positive = inward.

delta_temp: f64

Temperature delta for thermal stress calculation (°C).

alpha_cte: f64

Coefficient of thermal expansion (1/°C) — typically 9e-6.

sealant_width: f64

Silicone joint width (m).

sealant_shear_strength: f64

Silicone design shear stress capacity (Pa) — typically 0.14 MPa.

Implementations

impl StructuralGlass

pub fn monolithic_10mm() -> Self

Default single glazing: 10 mm monolithic, 3×5 m panel.

pub fn self_weight_pressure(&self) -> f64

Self-weight per unit area (Pa = N/m²).

pub fn max_bending_stress_wind(&self) -> f64

Maximum bending stress under uniform wind pressure (Pa).

Approximated as simply supported plate: σ = α · q · a² / t², where α ≈ 0.287 for a/b = 1.67 (typical facade aspect ratio), a is the shorter span, t is thickness.

pub fn thermal_stress(&self) -> f64

Thermal stress in a fully restrained glass pane (Pa).

σ_thermal = E · α · ΔT

pub fn combined_stress(&self) -> f64

Maximum combined stress (wind + thermal) (Pa).

pub fn sealant_shear_capacity(&self) -> f64

Structural silicone joint capacity check.

Returns the maximum transferable line load (N/m) via the silicone bead, limited by the sealant shear strength and joint geometry.

pub fn edge_reaction_wind(&self) -> f64

Wind load reaction at each of the four edges (N/m) for a simply supported panel.

pub fn centre_deflection_wind(&self) -> f64

Centre deflection under uniform wind pressure (m).

Thin plate formula for simply supported edges: δ = β · q · a⁴ / (E · t³), β ≈ 0.0443.

pub fn span_deflection_ratio(&self) -> f64

Span-to-deflection ratio (serviceability check; ≥ 200 typically required).

pub fn igu_self_weight_pressure(&self) -> f64

Insulating glass unit (IGU) sealed unit weight per unit area (Pa).

Assumes 16 mm argon cavity + second pane of equal thickness.
