DURABILITY OF CONCRETE INFRASTRUCTURE

摘要

Use of fiber composites for the enhancement of concrete structural durability is discussed. Computer methods are utilized to evaluate the progressive damage and fracture tolerance characteristics of example fiber composite enhanced concrete structures. The methodology is based on an iterative reanalysis/reevaluation method to simulate progressive damage and fracture in structural concrete with various reinforcement systems. A continuous fiber composite mechanics module is used to evaluate the properties and stress limits of glass/epoxy reinforcement systems. The developed simulation method enhances structural concrete design by providing a tool for the rapid evaluation of fiber-composite reinforcement materials and configurations with regard to durability and damage tolerance.
