摘要
文章根据某实际钢-混组合桥梁结构,设计了钢-钢纤维混凝土组合梁剪力连接件推出试件,对其极限抗剪强度及疲劳性能进行了相关试验,研究了静载破坏与疲劳破坏的形式,得到了结构的极限剪切强度和荷载-滑移曲线及相关疲劳曲线,根据τb、τs和τ-1画出了剪力连接件Goodman疲劳极限图。试验表明,文中所提出的计算方法和试验结果可供工程设计参考应用。
According to a real steel-concrete bridge structure, the steel-steel fibre concrete test samples are designed to test the ultimate shearing strength and fatigue performance. The destruction forms un- der static load and fatigue load are Found out respectively. The mechanical properties such as ultimate shearing strength, load-sliding curve, lg τmAx-lg N and lg △τ-lg N curves are gotten. The Goodman fa- tigue limit diagram is drawn based on τb,τS and τ-1. The calculation method proposed and the test re- sults obtained can be reference for practical engineering design.
