Abstract: This study investigated the failure behaviour, energy absorption response and load carrying capability of fibre-glass (FG)/natural silk fibre (NS)/epoxy hybrid composite cylindrical tubes subjected to an axial quasi-static compression test. The reinforced cylindrical composite tubes were prepared using mandrel assisted hand lay-up technique. The specimen tested were three (3) fibre-glass cylindrical tube, each consisting of 5 layers of (FG); three (3) natural-silk fibre cylindrical...
Abstract: Zinc oxide (ZnO) is a naturally occurring n-type semiconductor which is viewed as a promising candidate to replace indium tin oxide (ITO) in opto-electric applications, owing to its natural abundance and a wide bandgap (3.37). Synthesis of ZnO thin films via chemical spray pyrolysis technique is more convenient and cost effective compared to the mostly used deposition techniques such as magnetron sputtering which are highly expensive. Chemical spray pyrolysis provide easier way of ...
In addition to the inherent advantages of an outrigger system over conventional framed structural system, damped-outrigger systems (DOS) enhance it further with its agility to resist lateral loads in high-rise buildings. Dynamic response of slender and flexible buildings with DOS induces vibration control in which twisting of core structure is restricted by shear deformation of the damper present at the end of outrigger connected by perimeter columns. In this paper, a 300 m tall core-tube typ...
