【摘要】 网状CBF(Continuous Basalt Fiber,连续玄武岩纤维)增强砖砌体是将CBF布条按照特定的构造方式铺设在砌体水平灰缝砂浆层中,协同砖砌体共同工作的新型砌体结构形式。该文通过对5种不同横向配纤率,3种不同竖向纤维层构造的8组增强砖砌体试件进行轴心受压试验研究。初步试验结果表明:网状CBF增强砖砌体具有良好的强度储备,与无筋砖砌体相比,延性和轴心抗压强度都有明显改善。该文分析了试件的破坏形态和受力机理,以及对比横向配纤率和竖向配纤构造对砌体抗压性能的影响,最后,通过对试验数据的回归分析,给出了网状CBF增强砖砌体轴心承载力计算公式。更多还原

【Abstract】 CBF(Continuous Basalt Fiber) Mesh Reinforced Brick Masonry is kind of collaborating brick masonry with a new masonry structure,which laid CBF cloth stripes between mortar layers in accordance with a specific structure.This paper studies the axial compression test through 8 groups of reinforced brick masonry specimen of 5 different horizontal fiber rates and 3 vertical fiber layer forms.The preliminary test results show that: CBF Mesh Reinforced Brick Masonry has a good reserve of strength,and the ductility and axial compressive strength have been improved significantly,comparing to the unreinforced brick masonry.The failure modes of the specimen and the stress mechanism are analyzed,and the influence on masonry compressive properties of horizontal fiber ratios and that of vertical fiber layer structures is compared.Finally,the calculation formula of the axis bearing capacity of CBF Mesh Reinforced Brick Masonry by regression analysis of test data is conducted.更多还原
