Performance Analysis of CFST Column and RC Column Subjected to Eccentric Load

Applied Mechanics and Materials, 2011
A nonlinear finite element model is developed to study the behavior of square concrete-filled steel tubular(CFST) column and reinforced concrete (RC) column with the same quantity of material and cross-section sizes under eccentric load using ANSYS software.The results indicate that the bearing capacity of CFST column is about 30% greater than RC ...

Behaviour and design of demountable CFST column-column connections under tension

Journal of Constructional Steel Research, 2017
Abstract In the current construction practice, concrete-filled steel tubular (CFST) columns are difficult to be dismantled and relocated due to the continuous infilled concrete and reinforcement inside the columns. An innovative design method of the connections for CFST columns has been proposed herein, with which the CFST columns can be easily ...

Rigidity estimation of embedded CFST column-to-beam connections

Engineering Structures, 2017
Abstract This paper presents a finite element analysis (FEA) of embedded concrete-filled steel tube (CFST) column-to-beam connections subjected to combined axial-flexural loading. The proposed FEA model was verified by experimental results from previous research. The comparison and analysis show that the predicted local damages, failure patterns, and

Application of ANN to the design of CFST columns

Structures, 2020
Abstract In this paper, artificial neural network (ANN) is used to predict the ultimate strength of rectangular and circular concrete-filled steel tubular (CFST) columns subjected to concentric and eccentric loading. Four comprehensive datasets are compiled and used for developing ANN-based predictive models. Empirical equations are also derived from

Experimental and Numerical Investigations of Bolted CFST Beams–CFST Columns Connections

Iranian Journal of Science and Technology, Transactions of Civil Engineering, 2018
The effectiveness of concrete-filled steel tubular (CFST) sections as compression and flexural members has been investigated by many authors. The combined utilization of CFST columns and steel beams has increased in composite building construction in recent years, but combined use of CFST columns and CFST beams is still unexplored.

Effects of debonding on circular CFST stub columns

Journal of Constructional Steel Research, 2012
Abstract Core concrete subjected to confinement effect from steel tube is the main advantage of concrete filled steel tubular (CFST) column under compression. However, this beneficial composite action could be weakened even destroyed by debonding, which is almost unavoidable as a common phenomenon in CFST structures and has not been considered ...

Global Buckling Behavior of CFST Columns with Assembling Errors

International Journal of Structural Stability and Dynamics, 2022
Concrete-filled steel tubular (CFST) column has been widely used in engineering practice. In the process of assembling two columns to form a slender member, assembling errors (AE) are inevitably produced at the section of connection. When the AE are too large, the global buckling resistance of slender column would be significantly affected. Therefore,
