1. Buckling of Slender Concrete-Filled Steel Tubes with Compliant Interfaces
Abstract This paper presents an exact model for studying the global buckling of concrete-filled steel tubular (CFST) columns with compliant interfaces between the concrete core and steel tube. This model is then used to evaluate exact critical buckling loads and modes of CFST columns. The results prove that interface compliance can considerably reduce the cr

2. Temperature field of concrete-filled steel tubular columns in fire
Abstract The composite structures formed by the association of steel profiles with concrete have shown to be an advantageous alternative, improving the behavior of the steel structures concerning their load capacity, stiffness, and durability, under fire conditions. The concrete-filled tubular columns have become an attractive alternative for the civil const

3. Numerical study of confinement in short concrete filled steel tube columns
This study presents a numerical investigation into the behaviour of short concrete filled steel tubular (CFST) columns. Three Dimensional Nonlinear finite element analysis of the compression process is performed using commercial software ABAQUS v6.9 (2009). Steel tubes of different geometries and in-filled with different grades of concrete are chosen for mod

4. Experimental study about the fire effect in short composite column of steel and concrete / Estudo experimental do efeito do fogo em pilares mistos de aço e concreto
The use of circular hollow steel filled with concrete as columns are of great importance in the structural area, because it allows steel tube and concrete working together, providing a greater capacity resistant and a longer fire exposure, in relation to the same materials analyzed separately. This work will provide technical information for understanding th

5. Estudo da aderência aço-concreto em pilares mistos preenchidos / Study of bond on concrete-filled steel tubes
Este trabalho aborda o estudo da aderência aço-concreto em pilares mistos preenchidos através de revisão bibliográfica e de investigação experimental. De modo esquemático, a aderência é dividida em três parcelas: adesão, aderência mecânica e atrito, que em conjunto compõem a aderência natural. Adicionalmente, podem ser empregados conectores d

6. Theoretical and experimental study of high strength concrete filled steel tubes / Estudo teórico-experimental de pilares mistos compostos por tubos de aço preenchidos com concreto de alta resistência.
The use of concrete filled steel tubes especially in tall buildings is a tendency in several european, american and asian countries. The use of these members has several advantages: high resistance and ductility, saving of materials and labour, reduction of cross section dimensions and improvement in behaviour of the materials steel and concrete due the conf
