BAB 5 PLAT LANTAI
5.1. Perencanaan Plat Lantai
Gambar 5.1. Denah Plat lantai
5.2. Perhitungan Pembebanan Plat Lantai Plat Lantai
a. Beban Hidup qL Berdasarkan PPIUG untuk gedung 1983 yaitu :
Beban hidup fungsi gedung untuk swalayan tiap 1 m = 250 kgm
2
b. Beban Mati qD tiap 1 m Berat plat sendiri
= 0,12 x 2400 x 1 = 288 kgm
Berat keramik 1 cm = 0.01 x 2400 x 1
= 24 kgm` Berat Spesi 2 cm
= 0,02 x 2100 x 1 = 42 kgm

Berat plafond + instalasi listrik = 25 kgm
Berat Pasir 2 cm = 0,02 x 1,6 x 1
= 32 kgm qD = 411 kgm
c. Beban Ultimate qU Untuk tinjauan lebar 1 m pelat maka :
qU = 1,2 qD + 1,6 qL = 1,2 .411 + 1,6 . 250
