SEISMIC HAZARD ANALYSIS OF THE BANDUNG TRIGA 2000 REACTOR SITE
No full textSEISMIC HAZARD ANALYSIS OF THE BANDUNG TRIGA 2000 REACTOR SITE. A seismic hazard analysis of the West Java region is carried out to estimate the peak ground acceleration at the Bandung TRIGA 2000 nuclear reactor site. Both the probabilistic and deterministic approaches are employed to better capture the uncertainties considering the enclosing fault systems. Comprehensive analysis is performed based on the newly revised catalog of seismic data, the most recent results of the construction of seismogenic structures, and on the up dated information on the geology and the seismicity of the region. Source parameters such as b-value, slip rate and maximum magnitude are reassessed for each seismic source. As none attenuation equation is available for the region, those developed some where else are used in the study, i.e., Abrahamson & Silva (1997); Boore, Joyner & FumaI (1998); Boore & Atkinson (1997); Campbell & Bozorgnia (2003); Sadigh (1997); Spudigh (1997) and Young (1997). They are properly selected by considering the fault and subduction systems in question and are incorporated in the logic tree models derived herein based on the total probability theorem. The objective is to generate a horizontal three dimensional uniform risk spectral acceleration as dependent on the period as well as the return period for rock that is characterized by its average shear wave velocity of Vs = 1.050 m/s. A particular value of 0.172g is obtained as the peak ground acceleration for the site with its return period of 500 years
Collapse Risks of Fail-Safe RC Frames Due to Earthquakes: Fragility Assessments
No full textThe objective of this study was to determine the collapse risk of fail-safe reinforced concrete (RC) frames due to earthquakes by newly developed fragility curves. The curves were constructed based on the collapse mechanism, instead of measures of lateral drift as customarily adopted. The procedure was applied to RC open frames that were seismic resistant. A fail-safe mechanism was imposed by allowing plastic hinges to be formed mainly in the beams. This automatically satisfied the stronger column-weaker beam requirement; shear failure was neither tolerated anywhere in the columns nor in the beams. Two kinds of fail-safe RC frames were investigated: special moment resisting frames (SMF) and ordinary moment resisting frames (OMF). Their earthquake collapse risk was computed and compared. Inelastic time history (NLTH) and the non-linear static procedure (NSP) were conducted to assess their structural performance. The results showed among others that the fail-safe OMF had lower collapse risk than the fail-safe SMF. The collapse prevention performance level in NLTH could only be achieved for the fail-safe frames. The non-linear time history analysis should be the only method used for seismic reevaluation/safety checking of building frame structures
EXTERNAL EVENTS DARI REAKTOR RISET MENUJU REAKTOR DAYA
No full textEXTERNAL EVENTS DARI REAKTOR RISET MENUJU REAKTOR DAYA. Krisis energi yang dialami oleh Indonesia belakangan ini memerlukan adanya alternatif pembangkit listrik dengan energi terbarukan dan pembangkit listrik tenaga nuklir (PLTN) merupakan salah satu pilihan yang dapat dipertimbangkan. Standar keselamatan dan keamanan secara internasional perlu diterapkan termasuk di dalamnya standar untuk mengatasi kejadian-kejadian eksternal (external events). Di indonesia terdapat tiga reaktor nuklir riset yaitu reaktor Kartini di Yogyakarta, Reaktor TRIGA 2000 di Bandung, dan Reaktor GA Siwabessy di Serpong. Untuk menuju ke PLTN maka perlu diperhatikan pengalaman yang diperoteh dari reaktor riset tersebut. Makalah ini memuat pengataman dan kajian kejadian-kejadian eksternal (external events) sehubungan dengan qualifikasi dan re-evaluasi reaktor daya riset dengan studi kasus kajian kegempaaan yang telah dilakukan pada Reaktor TRIGA 2000, Bandung. Kajian kegempaan terhadap Reaktor TRIGA 2000 dibagi menjadi tiga tahap, yaitu investigasi lapangan, analisis resiko kegempaan (PSHA), dan analsis struktur. Pengalaman Indonesia dalam hal qualifikasi dan re-evaluasi reaktor riset sangatlah berharga sebagai bekal dalam pengembangan reaktor daya. Falsafah pengembangan reaktor daya adalah sejalan dengan reaktor riset dalam hal kejadian-kejadian eksternal. Perbedaannya adalah dalam hal besaran-besaran kuantitatif Performance Goal-Probability of Failure, Hazard Category, Safety dan Design Class
Perlindungan Hukum terhadap Pengetahuan Tradisional Marosok Sebagai Budaya Masyarakat di Sumatera Barat
No full textTraditional Knowledge is part of Intellectual Property Rights. Marosok is one of the cultures of the Minangkabau people in West Sumatra. Its categorized as traditional knowledge because the tradition comes from ideas or inventions which then become habits and caried out from generation to generation. Habits becomes a culture in the community. Legal protection is given to Marosok as an acknowledgment that Marosok cultureis a tradition of the Minangkabau people. In addition, to avoid any recognition from other parties outside the indigenous peoples where the culture originates. To find out more about how legal protection is given to Marosok and as one of the traditional knowledge in West Sumatra and how the Indonesian Government prevents the claim of intellectual property rights for Indonesian culture, especially Marosok by other countries, the author conducted a study on Legal Protection against Marosok traditional knowledge as Minangkabau community culture in West Sumatra. This study uses a qualitative method analytical descriptive nature prioritizing research on secondary data supported by the result of the field research. Data Analysis based on research, it can be seen that legal protection is needed for Marosok as traditional knowledge of the Minangkabau people of West Sumatra. The method of data collection is through library research and field studies
