Abstract Composite sections are found to be a novel technique in modern day scenario of construction. This stands tall than the ordinary and conventional type constructions. Columns as structural element play vital role frame. research comments on behavior composite columns. The main objective this study is analyze steel-encased concrete columns experimentally under axial compression mode failu...

The Yale art historian George Hersey showed us the columns in Figure 1 and asked us whether the ideas of symmetry breaking could be used to help classify architectural columns. Provoked by this question and the intriguing columns in that figure, we attempted to answer Hersey in the following way. We view a column as a deformed cylinder and column symmetries as the subgroup of the symmetries of ...

As a result of the excellent performance under different loading conditions, concrete-filled steel tubular (CFST) stub columns are extensively used recently. The current study employs 3D finite element analysis to assess response when subjected axial compression. effect some parameters concrete and confining tube where numerically investigated. was considered as an elastic perfectly plastic mat...

Abstract The objective of this study was to investigate the effectiveness soil–cement (SC) columns, provided either individually or in combination with lime on stability embankment constructed soft consolidating soil. evaluated terms both settlement and factor safety at various time intervals during consolidation. columns studied numerically using two-dimensional plane strain finite element met...

This research examines the electromechanical characteristics of self-sensing cement composite (SCC) containing activated charcoal (AC) at various concentrations (5%, 10%, 15%, 20%, and 25%). The developed is placed in zones beam to monitor behaviour, as well column center deflection. reveals that AC reduced compressive strength resistivity composites by generating local hydration carbon accumul...

A convenient family member of composite columns is concrete filled double skin tube (CFDST); it contains two tubes concentric steel and also shell that there between them. The superior or equal potential offering characteristics CFDST are more than counterparts classical (CFST). purposes the present study to provide experimental investigation results into prestressed load-carrying capacity colu...

In this study, FRP jackets were investigated for their confinement effectiveness on rectangular RC columns. Thirteen reduced-scale short columns were tested to failure in axial compression. Variables investigated include: the type of fibers (AFRP, CFRP or GFRP), the thickness of the jacket, the aspect ratio of the rectangular cross section and the radii of the corners. For square columns, GFRP ...
