Abstract
Replacement of functionally obsolete structural members is not the answer in sustainable construction market. Sustainable methods should be adopted to increase the load carrying capacity structures/members to increase their service life. In order to increase the load carrying capacity and/or increase the service life of existing reinforced concrete columns, Carbon Fibre Reinforced Polymer (CFRP) composites could be utilized. It provides good confinement to the concrete column core, which enhances the bending and compression strength as well as ductility. This paper presents an analytical concrete confinement model that reflects the effects of humidity on the mechanical properties of CFRP composites, and consequently, the humidity effects on the efficiency of CFRP in strengthening concrete columns. Tensile strength and modulus in humidity, and their effects on the concrete confinement are the two primary parameters that will be investigated. A modified concrete confinement model is developed and presented.
