Safety Evaluation of Submerged Weir Based on Seismic Probabilistic Limit State Design


Abstract eng:
While probability theory has been applied to the assessment of building safety in many areas, probability theory is less utilized in the numerical analysis of concrete structures. For social infrastructure and other large-scale concrete structures, few studies have been reported on safety against earthquakes, one of the most devastating natural disasters occurring in the world today. For this reason, numerical analyses using probability theory were performed on proposed seismic scenarios in the current study. Safety evaluations are conducted on submerged weirs that have been constructed as social infrastructure. Since there are limitations to using real-time numerical analysis to assess the safety of weirs after a natural disaster, a safety evaluation chart was developed by performing numerical analysis using probability theory on a pre-designed earthquake scenario. A safety evaluation was carried out based on the performance and serviceability of weirs under limit state design. This paper presents a methodology for developing safety evaluations of submerged concrete weirs to assess their performance against earthquakes. The methodology was illustrated using the Gangjeong-Goryeong weir, which was designed in the early 2010s, on the Nakdonggang river in Gyeongsangbuk-do in South Korea.
