本文分析了混合玻璃纤维增强聚合物（GFRP）和钢筋增强的高强度混凝土梁的弯曲性能。为了验证钢筋层布置和支撑设计对混合钢筋混凝土结构的影响，我们对混合钢筋混凝土梁的抗弯强度、荷载挠度和裂缝行为进行了实验研究。测试了四根梁，包括一根仅用 GFRP 钢筋加固的控制梁。加强层的布置是考虑的主要参数。提出了理论模型来预测最终容量和失效模式。 (c) 2012 Elsevier Ltd. 保留所有权利。
This paper analyzes the flexural behavior of high strength concrete beams reinforced with hybrid glass fiber reinforced polymer (GFRP) and steel reinforcements. To verify the influence of the arrangement of rebar layers and support design of concrete structures with hybrid reinforcement, we have experimentally investigated the flexural strength, load-deflection and crack behaviors of hybrid reinforced concrete beams. Four beams, including one control beam reinforced with only GFRP bars, are tested. The arrangement of reinforcement layers is the main parameters considered. Theoretical models are proposed for the prediction of ultimate capacity and modes of failure. (c) 2012 Elsevier Ltd. All rights reserved.
