1. Beban P1
a Beban Gording
= berat profil gording × panjang gording = 29.4 × 7,5 = 220,5 kg
b Beban Atap
= luasan abjk × berat atap = 14,156 × 50 = 707,8 kg
c Beban Plafon
= luasan abjk × berat plafon = 14,156 × 18 = 114,21 kg
d Beban Kuda-kuda
= ½ × btg 1 + 5 × berat profil kuda-kuda = ½ × 1,875 + 2,165 × 25
= 50,5 kg e
