5.1. Perencanaan Plat Lantai
Gambar 5.1 Denah Plat lantai
5.2. Perhitungan Pembebanan Plat Lantai
Berdasarkan PPIUG 1989 yaitu : a.
Beban Hidup qL Beban hidup fungsi gedung sekolah
= 250 kgm
2
b. Beban Mati qD
Berat keramik 1 cm = 0,01 x 2400 x 1
= 24 kgm
2
Berat Spesi 2 cm = 0,02 x 2100 x 1
= 42 kgm
2
Berat Pasir 2 cm = 0,02 x 1600 x 1
= 32 kgm
2
Berat plat sendiri = 0,12 x 2400 x 1
= 288 kgm
2
Berat plafond + instalasi listrik = 25 kgm
2
+ qD = 411
kgm
