This study presents the experimental and numerical investigations on structural steel-reinforced concrete (SRC) columns under combined axial lateral cyclic loadings. The main parameters evaluated are peak strength, mode of failure, hysteretic response, stiffness degradation, energy dissipation potential SRC columns. A parametric has been conducted using a finite element software ABAQUS to predi...

Eucalyptus nitens (E. nitens) has been much used for producing paper but also shows promise structural applications. In this study, static compressive tests were undertaken to examine its suitability be in an innovative composite column. The column was comprised of a rectangular steel tube with E. timber infill. nonlinear behaviour the filled wood both dry and wet conditions examined. same on t...

Recent earthquakes severely damaged short columns due to high lateral stiffness and low ductility. Some conditions, such as reductions in the heights of some compared others on same floor, deep beams, partially buried basements, non-structural walls, cause column effects. The prominent characteristics engineered cementitious composites (ECCs) reinforced with polyvinyl alcohol (PVA) fibers – inc...

This paper presents experimental research on structural behaviour of normal and recycled aggregate concrete filled steel tube (RACFT) columns externally strengthened with carbon fibre reinforced polymer (CFRP) sheets and subjected to axial loading. A total of 22 specimens were tested to investigate the influence of the following variables: (1) tube configurations, circular or square, solid or h...

Given the deterioration of civil infrastructure throughout world, developing more efficient repair and strengthening is essential. Jacketing one most common methods for retrofitting reinforced concrete (RC) columns. Notably, using engineered cementitious composite (ECC) within jacketing area increases bearing capacity significantly enhances ductility The recent development ECC with suitable com...

Abstract The behavior of concrete-filled double-skin poly vinyl chloride (PVC) tubular columns confined by plain PVC sockets is studied in this research. plastic pipes have been used with concrete as columns. has several advantages it inexpensive, light weight for construction, and decrease the time taken construction. Thus can be an alternative to metal various applications which maintenance c...
