Structural strengthening and seismic retrofitting of corrosion-damaged concrete structures

在地震区，钢筋混凝土结构的延性至关重要。以往的研究表明，钢筋因腐蚀而失去延性，可能发生突然破坏，危及结构安全。随着复合材料在强化应用中的广泛应用，由于复合材料的脆性和可能的过早脱粘，人们对强化后截面延性的潜在损失感到担忧。

Ductility of reinforced concrete (RC) structures is crucial in seismic regions. Previous research has shown that steel bars lose their ductility due to corrosion and abrupt failure may occur, thus jeopardizing the structure’s safety. With the wide use of composites in strengthening applications, concerns about the potential loss of section’s ductility after strengthening are raised due to the brittle nature of composites and their likely premature debonding.
