... ,针对剪切性能的研究比较少。 鲁静 [22] 、朱德举和许艾沿等 [23,24] 、姬瑞璞等 [25] 研究了 FRP 筋的树脂类型不同、使用环境不同及 受力状态不同对 FRP 筋剪切性能的影响。此外, 也有部分学者专门开展了 FRP 筋的剪切性能研究, 汪昕等 [26] 对不同类型 FRP 筋的剪切性能进行了系 统的研究,分析了树脂和纤维对剪切性能的影响 规律,并提出了考虑树脂和纤维影响的 FRP 筋剪 切 强 度 经 验 模 型 ;AhmedH.Ali 等 [27] 研究发现 FRP 筋的剪切性能具有明显的尺寸效应,剪切强 度随直径的增加而降低。虽然 FRP 筋的剪切性能 在上述研究中受到了关注,但仍未有学者明确提 出 FRP 筋剪切-拉伸强度关系模型。仅在较早时, 朱虹 [28] [29] Fig. 4 [27,[36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54] ...

... The use of high-strength and high-toughness (HSHT) steel bars has further enhanced energy absorption and crack control in reinforced concrete beams [16]. Due to the broad applicability of high-strength steel bars, not only their standard bending capacity but also their behaviour at elevated temperatures is being investigated [17]. Additionally, steel-basalt fibre composite bars (SBFCBs) have shown promise in addressing corrosion issues while maintaining ductility, indicating the potential for hybrid reinforcement [18]. ...
