Structural strengthening and seismic retrofitting of corrosion-damaged concrete structures

点击翻译按钮获取中文摘要

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.
