Modeling of moisture migration in an FRP reinforced masonry structure

A finite element model for hygro-thermo-mechanical analysis of masonry walls with FRP reinforcement

“…For a multi-layered structure, since the moisture content is discontinuous at the interface of different layers of constituent materials, a change of variable approach was taken by Lin et al [27] to substitute moisture content, y, with relative humidity, h, which resulted in the following form for the moisture diffusion equation:…”

“…Based on this consideration, the relative humidity of the surrounding air was used as the moisture potential for the current analysis [15].…”

“…A modeling scheme using the equivalent relative humidity of the surrounding air as the moisture potential to model isothermal moisture migration in an FRP/masonry structure has been developed by Lin et al [15]. In this study, the isothermal moisture migration model was extended to include the coupling effect of temperature gradient.…”

“…In most recent insulation technologies, the wall itself is made of several different layers. For these envelopes, the heat transfer, moisture transfer, and air infiltration, constitute a typical coupled heat and mass transfer process [1]. An accurate coupled heat, air, and moisture transfer (HAM) through porous media is of special interest in many engineering areas such as in the sphere of pollutants infiltration, drying in porous solids and soils, drying of woods and papers, soil mechanics, thermal insulation for buildings, etc.…”
