Experiences from 14 Years of Creep Testing of Steel and Polymer Fiber Reinforced Concreted to have a higher impact for polymer macro fibres than steel fibres. All setups have been tailored to specific applications and thus vary in size, applied load and pre-cracking deformation. The same holds for setups used by other research groups so that it is difficult to compare results. Based on暴行 发表于 2025-3-23 14:10:14

Tensile Creep of Cracked Steel Fibre Reinforced Concrete: Mechanisms on the Single Fibre and at the e load up to at least 50 % of the ultimate load after which the pull-out creep increases non-linearly. This can be ascribed to micro-cracking around the hooked-end of the fibre. Lastly, it is postulated that the interfacial transition zone between the fibre hooked-end and the concrete matrix plays a表两个 发表于 2025-3-24 00:32:18
Behavior of Cracked Cross-Section of Fibre Reinforced UHPFRC Under Sustained Load was used for a direct observation of the fibre inside the concrete. A correlation between experimental results with large scatter and specimen fibre distribution and orientation is sought in this way.monopoly 发表于 2025-3-24 02:46:40

Effect of Beam Width on the Creep Behaviour of Cracked Fibre Reinforced Concreteand the sustained bending stress was equal to 60 % of the stress .. of each prism. The results show that the specimen width has a minor effect on the results of creep tests in cracked state but the variability increases when the width decreases.割让 发表于 2025-3-24 23:39:28
