Description

Papers abstract:

Columns have traditionally been constructed of reinforced concrete or structural steel. Much attention was allocated to estimate the axial capacity of the traditional column sections to the detriment of other forms of construction. Other forms of column construction such as Concrete Filled Double Skin Tubes received little research attention, and almost no attention when subjected to eccentric loading. This paper investigates the axial capacity of columns when subjected to eccentric loading. The experimental axial capacities are compared to other established theoretical formulae on concentric loading to determine a possible relationship. The study found a good correlation between the reduction in axial capacity for different column lengths and hollow section ratios.

 

Product Overview:
This tutorial provides an investigation of the finite element modeling process used to analyze CFDST columns under eccentric compression. It details the key parameters affecting structural performance and offers insight into numerical simulation techniques. Key simulation steps include:

  • Development of CFDST column geometry and mesh refinement.
  • Definition of material properties and interaction between steel tubes and concrete core.
  • Application of boundary conditions and load cases.
  • Execution of nonlinear finite element analysis.
  • Post-processing and result interpretation.

 

In this tutorial, CFDST columns subjected to eccentric compression are simulated, according to data from the work of Haas and Koen.

More information

  • This tutorial package provides a complete workflow for analyzing steel-concrete composite beams under bending loads using ABAQUS. Researchers can easily adapt the model to study CFDST columns or other composite structures by modifying geometry and boundary conditions. This practical resource bridges academic research and engineering applications, offering insights into material behavior and interface interactions.
