Mechanical Behavior of Silica Fume Concrete Filled with Steel Tubular Composite Column

نویسندگان

چکیده

Recycling or utilization of industrial waste is becoming more popular as people become environmentally conscious. Silica fume a by-product the smelting process in silicon and ferrosilicon industries. This study examines mechanical behavior steel tubular composite column filled with conventional concrete silica experimentally under axial compressive loading. For study, variability tube thickness height constant diameter are considered. To explore influence concrete, microstructural analyses carried out by SEM, XRD, FTIR. The experimental results reveal that use replacement cement feasible; concrete-filled (SCFST) has marginal enhancement strength capacity compared to CFST increases.

Mechanical Behavior of Recycled Aggregate Concrete-Filled Steel Tubular Columns before and after Fire

Recycled aggregate concrete (RAC) is an environmentally friendly building material. This paper investigates the mechanical behavior of recycled aggregate concrete filled steel tube (RACFST) columns exposed to fire. Two groups of 12 columns were designed and tested, under axial compression, before and after fire, to evaluate the degradation of bearing capacity due to fire exposure. Six specimens...

Influence of Nano-Silica and Silica Fume in the Steel Corrosion Embedded in Concrete

Corrosion of steel is one of the most important potential dangers and threats in concrete structures. Corrosion of steel embedded in reinforced concrete plays a key role in reducing the strength and durability of reinforced concrete. Several studies have proposed that alternative approaches to enhancing the performance of reinforced concrete and its resistance to corrosion. In this study, the r...

Inelastic Behavior of Concrete-filled Thin-walled Steel Tubular Columns Subjected to Local Buckling

This paper is concerned with the inelastic behavior of axially loaded concrete-filled thin-walled steel tubular columns subjected to local buckling. A nonlinear fiber element analysis program accounting for local buckling effects is developed for predicting the ultimate strength and ductility of concrete-filled thin-walled steel tubular columns. The effects of local buckling are taken into cons...
