Research On The Reliability And Whole Process Quality Control Of The CFRP-reinforced Structures

Recently, an advanced composite material named Carbon Fiber Reinforced Plastic (CFRP) has emerged as an alternative to traditional strengthening materials. The existing reinforced concrete structures can be strengthened by externally bonded CFRP to improve their mechanical performances. Many advantages such as lightweight, non-corrosive, simple construction, and high tensile strength make it widely used in strengthening field. The existing research achievements mainly focuses on composite structure, construct measures and construction application. Based on the structural reliability theory, this article makes an approach to the reliability of the design strength for CFS (Carbon Fiber Sheets) and the reliability of the method for calculating the normal section flexural load-bearing capacity. Based on the structural reliability theory and quality control theory, combined with engineering practice, the whole process quality control theory including survey, design, call for tender construction and check before acceptance is put forward. At last this article tries to make the quality control procedures, check before acceptance on quality standards for the CFRP-reinforced project.
