Non-linear analysis of FRP chimneys under thermal and wind loads

摘要

Due to their high corrosion and chemical attack resistance, Fiber Reinforced Plastic materials (FRP) are increasingly being used in the construction of industrial chimneys. To the best of the authors' knowledge, the current study represents the first analytical investigation aimed at describing the behavior of FRP chimneys under the effect of both thermal and wind loads. The study is conducted numerically using a consistent shell element model which includes the effect of large deformations. A simple material non-linearity model that accounts for cracks occurring in the resin is added to the shell element model. The finite element model is used to describe the typical structural behavior of FRP chimneys, assess the effect of cracking and determine the critical through-thickness temperature profile.
