Design Response Spectra Based on Earthquake Hazard Maps and Specific Soil Properties at Indonesian Ports According to SNI 1726 2019

Indonesia has a new seismic code, namely SNI 1726 2019 (SNI 2019). It is developed based on the 2017 Indonesian Earthquake Source, Hazard Maps, and ASCE 7-16. This paper intended to explain procedure for calculating response spectrum according 2019, at ten ports located in Indonesia. The results are then verified with software RSA2019. Furthermore, it will be compared 2012 2012) see difference spectral acceleration value (Sa). result presents that Sorong Banggai have highest Sa, whereas port Banjarmasin smallest value. Port Surabaya Tuban nearly same Sa due their close location, while Banyuwangi slightly above them. Padang, Lampung, Penajam must use specific site analysis determine design spectra, which not discussed this paper. comparison shows spectra of higher than 2012. However, some areas such as Sorong, 0.1 0.6 s period larger 2019.
