dc.description.abstract | Korean Peninsula locates at Eurasia Plate, near the Pacific Plate which is located at it southwest. Korea is far away from the seismic belt, so the earthquake occurred there which magnitude was often small. So in South Korea, only seven percent of their houses has the seismic design. But, recently, earthquake hit the Korea, let the people started to concern this problem.
Probability Seismic Hazard Analysis is to simulate when specific earthquake occurred, its influences to each place, or the acceleration under different return period. We use PSHA to evaluate the earthquake hazard demand. For 475 years return period hazard map, the acceleration on the map represents that every 50 years at that location has 10% chance been exceeded. The result can be applied on many different areas. We can use this result on seismic design of building. For seismic design of building, it often use the 475 years period. And if the acceleration of 475 years period is 0.2g that represents buildings in that location need to resist 0.2g acceleration. For some important structure, like nuclear power plant or high-speed rail, higher years of return period should be considered. In the same location, higher return period has higher acceleration. It means the design is more conservative. For insurance company, combined with fragility, they can use the analysis to determine insurance premium and so .On this research, we adopt PSHA to do the Seismic Analysis of Korean Peninsula. | en_US |
