SEISMIC PERFORMANCE ANALYSIS OF WATER INTAKE BUILDING IN A NUCLEAR POWER STATION
-
摘要: 针对某百万千瓦级核电厂,运用动力时程反应分析法对取水口建筑物进行抗震分析。结合取水口建筑物场地岩性和结构特点,分别考虑运行和检修情况、波浪、冰块冲击、水压、土压和地震等作用的组合工况,对结构进行抗震性能分析,得到结构构件各个截面内力包络图,对取水口建筑物设计提供理论依据。Abstract: Based on dynamic time-history response analysis, seismic performance analysis of water intake building inthe million-kilowatt nuclear power plant was carried out.Considering rock properties and structural characteristics ofwater intake building, many combinations with different design water levels, operation and maintenance conditions, wave pressure, ice loadings, static and dynamic water pressure, earth pressure and seismic action were considered.The internal force of each section of the structure was obtained by secondary development of ANSYS and the resultscould provide theoretic evidences for the structural design of water intake building.
