Abstract

This paper reports on the long-term performance of CFRP strengthened concrete members subjected to 20–50 °C cyclic temperature, 60% constant humidity and sustained loading. The induced sustained stress was imposed through a range of loading values from 0% to 35% of the ultimate strength of specimens subjected to normal environmental conditions. The behaviour of CFRP/concrete lap shear specimens prepared using two types of commercially available two-part epoxy adhesives was investigated. Three different curing conditions were taken into account.
