本专著是基于作者近年来对受腐蚀破坏的钢筋混凝土结构的抗震性能评价和改造技术的研究成果而撰写的。首先，考虑应变率、初始静载的影响，建立了预测BFRP板和混凝土在静载下的行为以及BFRP板和混凝土之间的粘结行为的模型。其次，提出了提高槽锚固、钢板、锚栓锚固的混凝土梁构件性能的技术，建立了一个考虑初始裂缝位置、数量和高度的混凝土梁承载能力预测模型，并揭示了BFRP片改造梁的承载能力、刚度和延性等抗震性能的机理。第三，提出了BFRP腐蚀损伤钢筋混凝土柱的改造方法，揭示了腐蚀速率和FRP层对改善BFRP板的滞后性能、承载力、延性等抗震性能的影响。第四，研究了腐蚀损伤梁柱接头的抗震评价，并讨论了腐蚀速率和承重力之间的关系；此外，考虑到板、层和改造区域的影响，探讨了采用BFRP板改造的腐蚀损伤接头的抗震性能，提出了考虑腐蚀速率、BFRP片和地震损伤影响的节芯抗剪强度预测模型。第五，研究了腐蚀损伤剪力墙的抗震评价，并讨论了腐蚀速率和承载力之间的关系；考虑了X型和风机型锚的方法，探讨了腐蚀破坏型剪力墙和BFRP型未损坏剪力墙的抗震性能，提出了一种基于拉伸模型的BFRP板改造墙体剪切强度的修正预测模型。最后，提出了一个计算静态、动态和循环荷载下BFRP钢筋与混凝土黏滑关系的模型。
