混凝土梁碳纤维加固机理力法简析

ANALYSIS OF CONCRETE BEAM STRENTHENED WITH CARBON FIBER REINFORCED PLASTICS BY USING FORCE METHOD

摘要: 根据碳纤维加固梁的构造、加固机理和材料性能，将粘贴在梁体下侧的碳纤维视作一系列的链杆约束，用力法求解链杆的内力，从而确定了加固梁各部分的受力关系。并提出反映受力关系的系数K进一步探讨，说明系数K具有丰富的内涵，能够反映受力关系和碳纤维的加固作用。

Abstract: Based on the structure and material property of concrete beam strengthened with carbon fiber reinforced plastics (CFRP) and looked CFRP as a series of chain poles on the strengthened beam, mechanics model is built and analyzed by using the Force Method. A coefficient K is put forward and studied in this paper.
