This paper aims to experimentally study the fire performance of steel-reinforced concrete-filled steel tubular (SRCFST) columns without protection. Eight SRCFST specimens with cruciform section profiled were tested under ISO-834 standard fire. The various test parameters including cross-section type tube (circular or square), load ratio and eccentricity considered discussed. temperature distrib...

BACKGROUND & OBJECTIVES Prevention of malaria is a major technical and operational problem in displaced and mobile populations such as refugee camps and temporary labour settlements. Insecticide incorporated plastic sheeting is a new technology to control mosquitoes in emergency shelters and also temporary habitations at different locations. In view of this, efficacy of ZeroFly® , an insecticid...

Concrete filled cold-formed steel-concrete composite columns exhibit improved strength and ductility characteristics due to its ability resist inward buckling as well delay the outward buckling. Though concrete infill prevents buckling, still limits steel section from reaching yield strength. From past studies, it is observed that introducing of web stiffeners in cross-section may improve resis...

This paper reports a numerical study on the optimisation of lip size Z-sections under gravity loads. Numerical models cold-formed steel Z purlins restrained by cladding and angle struts subjected to sagging moment were developed validated against total 8 experimental results that failed in local or/and distortional buckling reported companion paper. Models varying levels complexity generated ke...

To investigate the mechanical behavior of profiled steel-concrete composite deck with modified clothoid (MCL) connectors under fatigue load, a method for calculating residual carrying capacity is proposed, and finite element (FE) model established to analyze mechanism decks after failure. The maximum error between theoretical test result 4%, model, 9%. indicates that capacities obtained from ac...

This paper focuses on the adverse effects of soil sodicity and alkalinity growth barley (Hordeum vulgare L.) in a rainfed environment south-western Australia. These conditions cause accumulation salt (called ‘transient salinity’) root zone, which decreases solute potential solution, particularly at end growing season as dries. We hypothesized that two approaches could help overcome this stress:...
