Kombinasi Pembebanan
Menurut SNI-03-2847-2002 –
Tata Cara Pembuatan Rencana Campuran Beton
Normal kombinasi beban untuk beton adalah sebagai berikut :
1.
1,4D ..................................................................................................................(2.25)
2.
1,2D + 1,6L.......................................................................................................(2.26)
3.
1,2D + L ± 1,0E ................................................................................................(2.27)
Dengan mempertimbangkan kombinasi beban gempa (E) dalam arah orthogonal
maka kombinasi beban gempa (E)dapat dibagi menjadi :
1,2D + 1,0L + (1,0X + 0,3Y) .................................................................(2.28)
1,2D + 1,0L + (1,0X - 0,3Y) .................................................................(2.29)
1,2D + 1,0L + (
-1,0
X
+0,3Y)................................................................(2.30)
1,2D + 1,0L + (
-1,0
X
- 0,3Y)...............................................................(2.31)
1,2D + 1,0L - (0,3X + 1,0Y) .................................................................(2.32)
1,2D + 1,0L - (0,3X – 1,0Y) .................................................................(2.33)
1,2D + 1,0L - (
-0,3
X
+ 1,0Y)...............................................................(2.34)
1,2D + 1,0L - (
-0,3
X
–
1,0Y) ...............................................................(2.35)
4.
0,9D ± 1,0E.......................................................................................................(2.36)
Dengan mempertimbangkan kombinasi beban gempa (E) dalam arah orthogonal
maka kombinasi beban gempa (E) dapat dibagi menjadi :
0,9D + (1,0X + 0,3Y) ............................................................................(2.37)
0,9D + (1,0X - 0,3Y) ............................................................................(2.38)
0,9D + (
-1,0
X
+ 0,3Y) ..........................................................................(2.39)
0,9D + (
-1,0
X
- 0,3Y) ..........................................................................(2.40)
