CARA MEMBUAT RESPONS SPEKTRA (SNI 1726 TH. 2012)

CARA MEMBUAT RESPONS SPEKTRA(SNI 1726 TH. 2012)

DISUSUN OLEH:

KOTA : PAREPARE

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

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

Fv = 1,44

SD (tanah sedang)

Fv = 1,68

SE (tanah lunak)

Fv = 2,56

5. Menghitung nilai SMS dan SM1

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

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

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

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

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

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
