ANALISIS PERBANDINGAN MODEL RESPON SPEKTRA DESAIN SNI 03-1726-2002, RSNI 2010 DAN METODE PSHA
ABSTRACT: Seismic load rules
for the building as outlined in the SNI 03-1726-2002 which divided
Indonesianarea in the 6 (six) earthquake regions. It is different to that in
RSNI 03-1726-xxxx, which dividedIndonesia area > 6 the seismic zone. In addition
earthquake time period use 500 years, while theRSNI 03-1726-xxxx uses 475 years
and 2475 years earthquake time period. In the arrangement ofPeak Ground
Acceleration values (PGA) is also used different attenuation formulas in
bothstandard. That's why research needs to be done to it by taking locations is
Kalibalok intersection(Bandar Lampung) and Way Robok (West Lampung) as objects.
The study focused on the shape ofthe response spectra design, in consideration
seismic load can be analyzed with dynamic analysismethods which one with the
response spectra. For add to the model, it was also use the methodPSHA
calculations PGA for both locations. Based on the SPT test data that has been
carried outby PT. Plato Isoiki, it turns out the two locations including the
classification in stiff soil profile.Refer to result of the response spectra
shapes in both locations is different. At the Kalibalokmaximum value of
acceleration response spectra if the design is made according to the results
ofPSHA calculations with one sigma models. Whereas for area Robok Way maximum
accelerationvalue is obtained if the design response spectra are arranged
according RSNI-03-1726-xxxx. Thisis because when the earthquake time period,
the attenuation function and seismic zoning isdifferent.
