火灾后钢筋混凝土梁柱节点性能分析
|
摘要
本文建立了火灾后钢筋混凝土梁柱节点有限元模型,在此基础上研究了火灾升温时间和柱轴压比对火灾后钢筋混凝土梁柱节点承载能力和延性性能的影响规律,研究结论可为受灾后工程评估或修复加固提供参考。
An finite element model of reinforced concrete beam-column joints after fire is proposed in the paper,based on which the influence of heating period and axial compression ratio of columns on the loading capacity and ductility of the joints is studied,several coclusions in this paper could be refered by safety assessment after fire or strengthening of engineerings.
