Design and Construction of the Cofferdam Pile with GFRP Reinforced Concrete

Abstract

FRP (Fiber reinforced polymer) is a two-way designed material from both macro and micro design. Former design was carried out according to the structural design, and the micro design is the material design on fiber volume ratio and the resin types. FRP is eminent in civil engineering because of its high strength to weight ratio, durability prolongation, high stiffness to weight ratio and its fatigue resistance behaviors. Right now, lots of applications were found in offshore engineering, hydraulic engineering and railway engineering. This article focused on both design and construction of the FRP reinforcement with concrete, and a case study was provided from the Nanjing city by CCEED (China Construction Eighth Engineering Division).
