LANGKAH-LANGKAH MEMBUAT RESPONS SPEKTRA

1. Tentukan nilai SS

SS adalah parameter respons spektra pada periode pendek 0,2 detik.

SS = 1,0 g

2. Tentukan nilai S1

S1 adalah parameter respons spektra pada periode 1 detik.

S1 = 0,36 g

3. Tentukan kelas lokasi

Untuk menentukan kelas lokasi, data yang dibutuhkan adalah nilai N SPT, cepat rambat gelombang, dan kuat geser niralir (undrained).

Untuk wilayah di Indonesia biasanya kelas lokasi yang digunakan adalah:

SC (tanah keras, sangat padat, dan batuan lunak),

SD (tanah sedang),

SE (tanah lunak).

4. Tentukan nilai Fa dan Fv

Tabel Koefisien Situs Fa

SC (tanah keras, sangat padat, dan batuan lunak)

Fa = 1

SD (tanah sedang)

Fa = 1,1

SE (tanah lunak)

Fa = 0,9

4. Tentukan nilai Fa dan Fv

Tabel Koefisien Situs Fv


Fv = 1,44

SD (tanah sedang)

Fv = 1,68

SE (tanah lunak)

Fv = 2,56

5. Menghitung nilai SMS dan SM1

SMS=Fa x Ss=1,0 x 1=1SM1=Fv x S1=1,44 x 0,36=0,518SMS=Fa x SsSM1=Fv x S1
SD (tanah sedang)
SMS=Fa x Ss=1,1 x 1=1,1SM1=Fv x S1=1,68 x 0,36=0,604
SE (tanah lunak)
SMS=Fa x Ss=0,9 x 1=0,9SM1=Fv x S1=2,56 x 0,36=0,921

6. Menghitung nilai SDS dan SD1
SDS=2xSMS3=2x13=0,67
SDS=2xSMS3SD1=2xSM13SD1=2xSM13=2x0,5183=0,345SDS=2xSMS3=2x1,13=0,733
SD (tanah sedang)
SD1=2xSM13=2x0,6043=0,403SDS=2xSMS3=2x0,93=0,6
SE (tanah lunak)
SD1=2xSM13=2x0,9213=0,614

7. Menghitung nilai T0 dan Ts


SD (tanah sedang)

SE (tanah lunak)
T0=0,2xSD1SDS=0,2x0,3450,67=0,103T0=0,2xSD1SDSTs=SD1SDSTs=SD1SDS=0,3450,67=0,518T0=0,2xSD1SDS=0,2x0,4030,733=0,109Ts=SD1SDS=0,4030,733=0,549T0=0,2xSD1SDS=0,2x0,6140,6=0,204Ts=SD1SDS=0,6140,6=1,024

8. Menghitung nilai Sa

Untuk periode lebih kecil dari T0
Sa=SDSx0,4 + 0,6TT0Sa=SD1T
Untuk periode lebih besar dari Ts

Untuk periode lebih besar atau sama dengan T0 dan lebih kecil dari atau sama dengan Ts, spektrum respons percepatan desainnya, Sa, sama dengan SDS
