Purpose-Social media has fundamentally changed the leisure travel behavior of Singapore residents. The purpose of this paper is to focus on Facebook and its impact on travel behavior. The study focuses on Singapore residents. Design/methodology/approach-A total of 16 input and five output variables were tested, with a sample of 203 Facebook users residing in Singapore. Primary data modeling was done using ADANCO, a structural equation modeling tool that uses composite modeling approach for hypothesis testing. The analysis performed an estimated structural model and then determined the best model fit by measuring reliability, validity and path analysis and estimating model parameters. Findings-Research findings indicate that Facebook has had a strong behavioral influence on the frequency of travel, itinerary planning and social sharing, while it had no impact during the destination-selection stage of travel planning. Originality/value-Facebook's influence on leisure travel behavior confirms the theory of planned behavior proposed by Icek Ajzen. From Facebook's perspective, the outcome of this study is helpful in recommending the best use of the platform for destination providers.

In current duration growing atmospheric high temperature and discharge of pollutants leads to environmental destruction became major issues in previous couple of decades. This study deals with the partial replacement of fine aggregate with steel slag in concrete filled steel tubular column to check the axial behaviour of column. Review from previous research found that fine aggregate replaced in concrete will reduce the effect of global warming and other environmental hazards.

Concrete column fails by crushing or bucking due to axial load in order to resist failure of confinement, concrete filled steel tubular column (CFST) and carbon fibre reinforced polymer (CFRP) wrapping are used. CFST member has its consecutive progression in the construction industries due to its high load carrying capacity upgraded ductile performance, need for form work is minimized and has greater confinement effect. CFRP wrapping provides resistance towards corrosion, light weight exceptional durability, increases strength over confinement. In this work, an experimental investigation between stunt and slender concrete filled steel tubular column is compared with conventional pcc strut and slender column externally wrapped by single and double layer of CFRP. Total of 8 specimen were tested under axial compression. The parameter varied is height (750mm, 1050mm). The diameter of the column is 75mm. M30 grade concrete is cast. End support condition is hinged. For short column slenderness ratio is 40, L/D is assumed to be 10 and for slender column slenderness ratio is 60 and L/D is assumed to be 14. From this study, the influence of slenderness ratio over an effect of confinement is observed. Maximum axial compressive strength of the column is recorded and it is compared with eurocode4, AS/ACI code, IS516:1959 code. The behaviour of column both experimental and analytical results is observed.
