Abstract

This paper presented the flexural behavior of the fast-hardening anti-disturbance concrete (FHADC) wet-joint beam after vibration of solidification period. Considering the influence factors of amplitude and frequency, 10 FHADC wet-joint beams were vibrated during solidification, then the beams were subjected to bending test. The results showed that: (1)The failure mode of wet-joint beams was bending-shear failure. (2)Simple harmonic vibration can cause more serious damage on beams, compared with low-cycle reciprocating vibration. The crack size increase with the increasing amplitude and frequency of the applied vibration. (3)Under low-cycle reciprocating vibration, the ultimate load of beam decreased by 1.8 % with the amplitude increased. (4)Under simple harmonic vibration, the ultimate load of beam decreased by 36.8 % with the increase of amplitude and decreased by 20.4 % with the increase of frequency. Finally, a calculation method for the flexural capacity of wet-joint beams has been proposed, which offers a reference for similar engineering design.

快硬化抗扰混凝土湿缝梁在凝固期振动后的受弯性能

本文研究了快速硬化抗扰混凝土湿缝梁在凝固期振动后的抗弯性能。考虑振幅和频率的影响因素，对10根FHADC湿接缝梁在凝固过程中进行了振动，并对其进行了弯曲试验。结果表明：(1)湿接缝梁的破坏模式为弯剪破坏。(2)简谐振动比低周往复振动对梁的损伤更严重。裂纹尺寸随外加振动振幅和频率的增加而增大。(3)在低周往复振动下，随着振幅的增大，梁的极限荷载减小了1.8 %。(4)简谐振动下，梁的极限荷载随幅值的增加而减小36.8 %，随频率的增加而减小20.4 %。最后，提出了湿缝梁抗弯承载力的计算方法，为类似工程设计提供参考。
