Pre-Engineered Buildings (PEB)

  • Loads: dead (IS 875-1), live 0.75 kN/m² roof (IS 875-2), wind pressure pz = 0.6·Vz² (IS 875-3)
  • Design wind speed: Vz = Vb·k1·k2·k3·k4
  • Steel estimate: typically 25–45 kg/m² depending on span and crane
  • Ventilators by air changes: n = volume x ACH / unit capacity
