Finite Element Analysis of Axially Loaded RPC Filled Long Circular Steel Tube Columns
In recent years, Reactive Powder Concrete (RPC) has been concerned by the structural engineers and researchers. RPC is a kind of cement-based composite which has ultra-high strength, high ductility and durability, however, it has great fragility. The fragility performance of RPC will be improved if RPC and steel are put together as RPC-filled steel tube circular stub columns. The aim of this paper is to develop accurate finite element models to simulate the behavior of RPC-filled steel tube circular long columns. The finite element program ABAQUS is used in the analysis. An extensive parametric study is conducted to investigate the effects of different slenderness ratio and confinement action on the strength and behavior of RPC-filled steel tube circular long columns. The results obtained from the models are verified against the results of the tests. The results show that the rising part of load-strain curves are in good agreements with experiment results.
