Abstract Strengthening steel structures using CFRP Laminates has recently attracted increasing attention. Several studies focused on the efficiency of this strengthening technique. However, little is known regarding efficiency when applied to steel plates with different levels of damage considering various strengthening schemes for loading conditions other than pure tension. In this research, fatigue behavior of cracked steel plates strengthened with CFRP laminates is experimentally investigated considering several parameters including strengthening scheme and level of damage. Samples are tested under eccentric cyclic loading and efficiency of repair is concluded. Then, a study is followed to examine reliability of available analytical models.

CFRP层压板加固不同损伤程度裂纹钢板的试验研究

摘要 使用 CFRP 层压板加固钢结构最近引起了越来越多的关注。一些研究集中在这种强化技术的效率上。然而，考虑到除纯张力之外的加载条件的各种强化方案，当应用于具有不同损伤程度的钢板时，关于效率知之甚少。在这项研究中，考虑到包括强化方案和损坏程度在内的几个参数，对用 CFRP 层压板强化的裂纹钢板的疲劳行为进行了实验研究。样品在偏心循环载荷下进行测试，得出修复效率。然后，进行一项研究以检查可用分析模型的可靠性。
