（淄博市規(guī)劃設計研究院，淄博255037）[摘 要]既有結構的改造加固設計必須考慮結構體系的優(yōu)化，及結構整體剛度、剛度分布和剛度變化的合理把握；組合構件必須考慮既有結構的舊有構件剛度，使計算更加符合實際情況；結構構件的剛度是逐漸退化的，既有結構的設計計算需考慮剛度退化的影響。[關鍵詞] 體系優(yōu)化;剛度調整;構件剛度;剛度退化中圖分類號：TU375.4 文獻標識碼：A 文章編號：1002-848X(2013)S1-0791-04Application of stiffness theory in the structural reinforcement designGuang Jun( Zibo urban planning design Institute, Zibo 255037,China)Abstract:Optimum design of structural system must be taken into account in the structural reinforcement design,and reasonable grasp the structural whole stiffness, stiffness distribution and stiffness changes. The structure stiffness of the old member must be considered in combined member, which makes the calculation more in line with the actual situation. Structure members’ stiffness is degraded, and should be considered the effect of stiffness degradation in the calculation of structural design.Keywords: system optimization; stiffness adjustment; stiffness of the structural member; stiffness degradation
