A study concerning the flexural behavior of glass beams reinforced with steel fibers is presented in this paper. Two types of steel fibers were used for reinforcement, made of high strength and stainless steel. The coupling effect of the two materials was studied in terms of energy dissipation and failure loads, by comparing the elastic limits and the post-elastic behaviors of the reinforced glass beams. Results demonstrated that it is possible to increase the overall structural safety of a steel fiber reinforced glass beam. The relationship between the bending force and deflections was initially linear, however, following the opening of first cracks in the glass, the reinforcement steel material was able to withstand the tensile stresses, governing the overall post-elastic phase.
本文介绍了一项关于钢纤维增强玻璃梁抗弯性能的研究。使用了两种类型的钢纤维进行增强，分别由高强度钢和不锈钢制成。通过比较增强玻璃梁的弹性极限和弹性后行为，从能量耗散和破坏荷载方面研究了这两种材料的耦合效应。结果表明，提高钢纤维增强玻璃梁的整体结构安全性是可能的。弯曲力与挠度之间的关系最初是线性的，然而，在玻璃中首次出现裂缝后，增强钢材能够承受拉应力，控制了整个弹性后阶段。
