基于离散单元法的房屋地震破坏数值模拟

NUMERICAL SIMULATION FOR EARTHQUAKE INDUCED DESTROY OF MASONRY BUILDING

    摘要
  • 摘要: 地震中砌体房屋倒塌破坏造成大量人员伤亡,本文采用基于离散单元法的颗粒流分析软件PFC3D数值模拟砌体房屋在地震作用下三维破坏过程。模拟结果能较好地反映结构的倒塌过程,为地震救援中刀具的改进和挖掘提供技术参考。

     

    Abstract: A mass of masonry building collapse destroyed during the earthquake.It caused a large number of casualties.In this paper, the destroy process of masonry building was simulated with Particle Flow Code in 3 Dimensions analysis software based on the Discrete Element theory.A reasonable agreement of structure destroy process is reached, to provide technical reference for earthquake relief in mining and tool improvements.
