Modern Venlo commercial greenhouses with gutter heights exceeding $6.5–8.0\text{ m}$ experience massive aerodynamic wind suction and overturning moments. Structural compliance with EN 13031-1 and NEN 3859 requires precise calculations combining dead loads, snow accumulation, dynamic wind pressure ($q_w \ge 0.50\text{ kN/m}^2$), and suspended crop trellis loads ($15–20\text{ kg/m}^2$).
1. The Ultimate Limit State (ULS) Equation
E_d = \gamma_G G_k + \gamma_Q Q_{k,1} + \sum \gamma_Q \psi_{0,i} Q_{k,i}
Ensuring column base moment resistance avoids catastrophic envelope buckling during extreme storm events.
