建筑结构加固设计原则有哪些?要根据相关标准进行可靠性鉴定;保留和利用原有结构和构件;考虑综合技术经济指标;处理好构件与结构、局部与整体、临时与较久的关系;修复加固的实施必须有科学的先后顺序;加固设计还应注意复核混凝土结构的抗震能力;还要考虑建筑美观，确保建筑结构加固的可靠性。
1.在结构加固设计前，应遵照《工业厂房可靠性坚定标准》和《民用建筑可靠性标准》进行可靠性鉴定，根据鉴定结果，确定加固设计的内容和范围;同时，根据结构破坏后果的严重程度及使用单位的具体要求，确定加固后房屋建筑结构的安全等级。

7.加固设计还应注意复核混凝土结构的抗震能力，做好抗震加固设计。地震区的结构或构件加固，除应满足承载力要求外，还应复核其抗震性能结构加固后不应存在因局部加强或刚度突变而形成新的薄弱部位，同时还应考虑结构刚度增大或变化而导致地震作用效应的增大或变化的影响。
