ABSTRACT

In recent years, hoarding design has been a source of major concern in city limits, since the damage can be risky to life and property. The handbook of wind loads (IS 875(Part3):1987&2015 codes) recommended the hoarding as a temporary structure with 5 years design life period risk factor. The recent developments in India expanded the tremendous outdoor picturesque advertisement hoardings in the city limits for the dissemination of the broadcasting information. The failure of hoarding can be high degree hazard resulting in the loss of human life, but the wind code cannot define the structure even as a low hazard class of structure. Hence this paper addressed the risk associated with 10, 15, 20 and 25 years of design periods in city limits of terrain category 2 of the five wind zones of India. The five wind zones comprise 33m/s,39m/s, 44m/s,47m/s and 50m/s have been considered because most of the populated cities have been geographically located in all the wind speed zones. To ascertain the influence of the above parameters, 15m × 6m steel elevated hoarding mounted on G+7 storey building is analysed in SAP 2000 version software. The associated risks are interpreted in terms of the variation of drag force, shear force and overturning moments. It can be highlighted when risk factor varied from 6% to 29%, the drag force, and overturning moments varied from 13% to 65%. Similar results were also obtained with cyclonic factor.
