爆炸压强在建筑物表面分布的数值模拟

Numerical simulation of the distribution of blast pressure on buildings

应用显式动力有限元软件AUTODYN建立了建筑物外部爆炸波传播的数值分析模型,分析了建筑物表面爆炸压强的分布规律,为在建筑物的抗爆设计中确定爆炸荷载模型提供了理论依据。

The numerical models of spread of blast wave outside buildings are established using AUTODYN, explicit dynamic finite element soft- ware. The distribution of blast pressure outside building is analyzed. Some principles in the design of a blast-resistant building are proposed to calculate blast loadings on the building.
