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

qD = 411 kgm

c. Beban Ultimate qU
Untuk tinjauan lebar 1 m plat maka : qU = 1,2 qD + 1,6 qL
= 1,2 . 411 + 1,6 . 250 = 973,20 kgm
