Nonlinear Finite Element Modeling of Concrete-Filled Circular FRP Arch Tubes under Monotonic Loading
This paper aims to develop a numerical model to predict the in-plane load-deflection behavior and the maximum load carrying capacity of concrete-filled circular FRP arch tube (CFFAT) which to date has rarely been investigated. The present model employs the well known fiber element approach to consider the material behavior of concrete core and external FRP tube. The composite arch was idealized as an assembly of stepwise two dimensional (2D) straight prismatic beam-column elements. The established FE model was then implemented into Opensees software framework to obtain the load-deflection characteristics up to the limit strength state of CFFAT under monotonic loading. Comparisons between the present numerical predictions and experimental results reported elsewhere were made concerning the load carrying capacity as well as the ultimate failure modes. The proposed analytical model was shown to provide, with sufficient accuracy for practical use, the estimates of nonlinear static behaviour of CFFAT.
