摘要

钢结构的抗连续倒塌能力一般取决于其抵抗局部损伤的能力

但这种能力往往取决于许多因素

目前还没有一个稳定可靠的判定方法。基于组件法建模原理将顶底角钢-腹板双角钢节点离散为多个对受力有贡献的基本组件

然后通过集成组件来模拟节点的受力特性

并依此构建了顶底角钢-腹板双角钢半刚性节点梁柱子结构的连续倒塌数值分析模型。结果表明:通过与试验结果比较

节点组件模型能较为准确地反映节点的断裂路径和受力发展过程

同时降低了计算成本。说明组件法在连续倒塌研究中具有重要的理论意义和应用价值

可作为连续倒塌研究的有利工具。

Abstract

The resistance to progressive collapse of steel structures generally depends on their ability to resist local damage.However

this ability depends on many factors that have not yet be identified in a methodical and reliable manner.The joints with top and seat angles and double web angles are discretized into a number of basic components that contribute to the stress using the component method

then their stress characteristics are simulated by the components integration.Based on it

the numerical simulation model for progressive collapse of substructures with this semi-rigid joint was built.Compared with the test results

the results show that the component joint models can accurately reflect the post-fracture path and internal force development of the joint with a cost-effective solution

which indicates that the component method has great theoretical significance and applicable value for the study on progressive collapse

and can be used as an effective tool in this field.
