采用外部粘贴FRP加固混凝土梁抗剪强度的设计计算

近年来 ,纤维增强复合材料 (FRP)越来越多地被应用于混凝土结构的加固与修复中 ,在日本、欧洲及北美已成为一种重要的加固手段。在国外以及国家工业建筑诊断与改造工程技术研究中心 (以下简称国家中心 )进行的FRP加固混凝土梁试验结果的基础上 ,提出了FRP抗剪加固混凝土梁的设计计算方法。该方法建立在理论和试验分析的基础之上 ,结果可信 ,具有实际应用价值

DESIGN CALCULATION OF SHEAR STRENGTH OF CONCRETE BEAMS STRENGTHENED WITH EXTERNAL BONDING FRP

In recent years,fiber reinforced plastics (FRP) have been used more and more for strengthening and repairing concrete structures,which has already become an important strengthening measure in Japan,Europe and North America.On the basis of the test results of the concrete beams reinforced with FRP conducted in foreign countries and in National Engineering Technology Research Center of Industrial Building Diagnosis and Rehabilitation,the design and calculation methods of the shear strength of the concrete beams strengthened with FRP are proposed,whose results are reliable and useful in actual applications.
