基于多尺度方法的钢结构停车库破坏机理

为了利用最小的计算代价得到钢结构外伸端板节点准确的局部分析结果和钢结构停车库的整体结构性能,引入了基于8节点六面体单元界面约束方程的多尺度有限元计算方法,从而使精细的微观单元模型可以同宏观单元模型实现不同尺度间的变形协调。通过算例验证了基于有限元软件ABAQUS建立的多尺度有限元模型和计算结果的准确性。采用多尺度方法分析了外伸端板节点连接的钢结构停车库的破坏机理,给出了由应变能判定钢结构停车库的失效准则。...

Abstract 为了利用最小的计算代价得到钢结构外伸端板节点准确的局部分析结果和钢结构停车库的整体结构性能,引入了基于8节点六面体单元界面约束方程的多尺度有限元计算方法,从而使精细的微观单元模型可以同宏观单元模型实现不同尺度间的变形协调。通过算例验证了基于有限元软件ABAQUS建立的多尺度有限元模型和计算结果的准确性。采用多尺度方法分析了外伸端板节点连接的钢结构停车库的破坏机理,给出了由应变能判定钢结构停车库的失效准则。
