Abstract

Gempa menghasilkan pembebanan pada suatu Jacket Platform melalui interaksi gerakan tanah dan karakteristik respon struktur. Tugas akhir ini menganalisa keruntuhan Jacket Platform dengan variasi Peak Ground Acceleration (PGA) berbasis resiko. Metode pushover non-linear untuk mendapatkan Reserve Strength Ratio (RSR) dengan incremental lateral load berupa beban gempa hingga struktur collapse. Penerapan analisa pushover non-linear dalam hal material dan geometri. Analisa non-linear menghasilkan RSR yang lebih akurat dibading analisa linear. Diperoleh RSR terkecil pada PGA 0,25g yaitu 2,082 dengan probability of failure (pof) sebesar 0,0461. Resiko Jacket Platform akibat beban gempa termasuk dalam Risk level 2 dalam API RP 2 SIM (System Integrity Management). =============================================================================================== Seismic load on a Jacket Platform through the interaction of ground movement and the character response of the structure. This final academic project is to analyze the risk of Jacket Platform collapse with Peak Ground Acceleration (PGA) variations. Non-linear pushover method used to obtain the Reserve Strength Ratio (RSR) with incremental seismic lateral load until the structure collapse. Application of non-linear pushover analysis in terms of material and geometry non-linearity. Using non-linear approach, the RSR produces more optimist and accurate than linear approach. The smallest RSR of 2,082 is found on 0.25g PGA with probability of failure (pof) 0.0461. Platform Jacket risk category due to seismic loads are included in the Risk level 2 in API RP 2 SIM (System Integrity Management).
