摘   要:为了研究BFRP筋混凝土梁的抗弯性能,进行了不同配筋率和不同配筋形式BFRP筋混凝土梁的四点弯曲试验,分析了试件的跨中挠度、抗弯承载力和裂缝分布规律。结果表明:BFRP筋混凝土梁的弯矩-挠度曲线表现出试件开裂、峰值弯矩为转折点的三折线特征;BFRP筋与钢筋混合配筋梁的弯矩-挠度曲线表现出试件开裂、钢筋屈服和峰值弯矩为转折点的四折线特征;BFRP筋与钢筋混合配筋能提高钢筋混凝土梁的抗弯承载力,减小BFRP筋混凝土梁的挠度和裂缝宽度,同时发挥BFRP筋强度高的特点;BFRP筋与钢筋混合配筋梁符合平截面假定,并给出了正截面抗弯承载力计算公式。 Abstract: In order to study the flexural performance of concrete beams reinforced with BFRP rebar, the four-point bending tests of BFRP reinforced concrete beams with different reinforcement ratios and different reinforcement forms were carried out, and the mid-span deflection, flexural capacity, and crack distribution of the specimens were analyzed. The results show that the bending moment-deflection curves of BFRP reinforced concrete beams show the characteristics of three-fold curve with specimen cracking and peak bending moment as the turning point. The bending moment-deflection curves of beams reinforced with BFRP rebar and steel rebar show the characteristics of four-fold curve with specimen cracking, steel yield and peak bending moment as the turning point. The mixed reinforcement of BFRP rebar and steel rebar can improve the flexural capacity of the reinforced concrete beams, reduce the deflection and crack width of BFRP reinforced concrete beams, and the strength of BFRP rebar can be sufficiently utilized. The beams reinforced with BFRP rebar and steel rebar conform to the plane section assumption, and the calculation formula of flexural capacity of the beams is given.

(1)BFRP筋混凝土梁的弯矩-挠度曲线表现出试件开裂、弯矩峰值为转折点的三折线特征;BFRP筋与钢筋混合配筋梁的弯矩-挠度曲线表现出试件开裂、钢筋屈服和弯矩峰值为转折点的四折线特征。
(2)随着BFRP筋与钢筋配筋比例的增加,BFRP筋混凝土梁和BFRP筋与钢筋混合配筋梁的裂缝宽度增大,抗弯承载力增大,跨中挠度减小。
(3)混合配筋梁比单一BFRP筋混凝土梁更能抑制混凝土裂缝的开展;通过混合配筋的形式能够提高钢筋混凝土梁的抗弯承载力,减小BFRP筋混凝土梁的跨中挠度,充分发挥BFRP筋强度高的特点。
(4)本文提出的BFRP筋与钢筋混合配筋梁的正截面抗弯承载力计算公式的精度较高。
