To represent the structural behavior of self-compacted concrete filled steel tube composite columns under axial compression loading after high temperatures exposure, a nonlinear three dimensional finite element analysis model has been achieved to analyze these using ANSYS R-15 software. An eight-node solid brick (Solid65) is used concrete, while four-node isoparametric shell (Shell63) for analy...

As a new member of concrete-filled steel tube (CFT) structural families, elliptical tubes (CFETs) have great potential to be used as piers and columns in bridges airport terminals because its low flow resistance coefficient reasonable distribution major–minor axis. Hence, the main objective this paper presents an experimental investigation on seismic behavior terminal stirrup-confined (TS-CFET)...

ABSTRACT: The design of steel and concrete composite columns in a fire situation is directly linked to the reduction strength stiffness, among other properties, which are manifested response rising temperatures. normative codes that deal with these elements under action consider thermal based on heating four faces column, an aspect does not cover most cases buildings due presence walls. In this...

Abstract. Due to age, structural deterioration, and other factors, concrete constructions such as beams columns will inevitably deteriorate. The growth of nanomaterials recent advances in multidisciplinary research has broadened cement composites' applicability various fields. A self-sensing composite can detect its own deformation, strain, stress by changing electrical characteristics, which m...

In recent years, rehabilitation has been the subject of extensive research due to increased spending on building work and repair of built works. In all cases, it is absolutely essential to carry out methods of strengthening or repair of structural elements, and that following an inspection analysis and methodology of a correct diagnosis. The reinforced concrete columns are important elements in...
