Abstract

Abstract This study conducted an analytical investigation on the behavior of concrete beams with openings reinforced by glass-fiber-reinforced polymer (GFRP) bars. In this study, five proposed beams reinforced by GFRP bars as flexural and shear reinforcement with openings were numerically examined. The variables were the opening orientation (vertical and horizontal) and the number of openings. These openings were located within the flexural zone of the proposed beams. The result shows that the vertical openings had a significant effect over the horizontal openings on reducing the ultimate load and increasing the mid-span deflection compared with the control beam. Moreover, the results showed that when replacing two adjacent openings by one equivalent opening, the capacity of the beam is decreased.

玻璃纤维增强聚合物（GFRP）钢筋加固水平和垂直开口混凝土梁的弯曲性能

摘要本研究对玻璃纤维增强聚合物（GFRP）钢筋加固开孔混凝土梁的性能进行了分析研究。在本研究中，对五个拟采用GFRP钢筋作为开口抗弯和抗剪钢筋的梁进行了数值分析。变量是开口方向（垂直和水平）和开口数量。这些开口位于拟建梁的弯曲区内。结果表明，与控制梁相比，竖向开孔在降低极限荷载和增加跨中挠度方面比水平开孔有显著的效果。此外，结果表明，当用一个等效开孔替换两个相邻开孔时，梁的承载力会降低。

期刊介绍： The journal focuses on the micromechanics and nanomechanics of materials, the relationship between structure and mechanical properties, material instabilities and fracture, as well as size effects and length/time scale transitions. Articles on cutting edge theory, simulations and experiments – used as tools for revealing novel material properties and designing new devices for structural, thermo-chemo-mechanical, and opto-electro-mechanical applications – are encouraged. Synthesis/processing and related traditional mechanics/materials science themes are not within the scope of JMBM. The Editorial Board also organizes topical issues on emerging areas by invitation.
