Hollow concrete columns are often employed in bridge constructions because of their lighter weight and effective section characteristics. In addition, to reduce the issue steel reinforcement corrosion create a strong light construction, hollow also reinforced with bars made fiber-reinforced polymer. This research aimed analyze effect GFRP (glass fiber polymer) on compression strength square und...

Fused Deposition modelling (FDM) technology is based on decomposition of 3-D computer models into thin cross sectional layers, followed by physically forming the layer and stacking them up layer by layer. FDM provide freedom to add material in the desired area and we are also able to create hollow region in certain portion of layer. In this way low weight with good strength single ply raw mater...

thin-walled hollow steel columns, either circular or box shaped, are commonly used as piers in bridges. recent earthquakes, e.g. hyogoken-nanbu or kobe 1995, on the other hand have shown that these columns are vulnerable to damage when subjected to earthquake loading. this paper presents a new innovative thin-walled hollow steel column fabricated of corrugated plates, “thin-walled steel columns...

The elliptical hollow section has been recently included in the family of structural steel sections. This type is also used production concrete-filled tubular (CFST) members. For CFST compression members, there no specific design formulation current provisions, except code called “Technical for structures” prepared by Ministry Housing and Urban-Rural Development People’s Republic China. However...

This paper reports an experimental and numerical study of the cross-sectional behaviour cold-formed high-strength steel (HSS) square rectangular hollow section (SHS RHS) members. Six stub column tests, six 3-point three 4-point bending tests have been carried out, followed by development accurate finite element (FE) models a parametric study. Based on test FE results, design rules for slender c...

ABSTRACT This article describes the finite element analysis of concrete columns with a hollow square reinforced which restricted Carbon-Fiber-Reinforced polymer (CFRP) tube. In this study, about sixteen core were investigated. These classified into four sets. The set number one was reference involved unconfined traditional steel helices and longitudinal bars. 2nd category have similar configura...
