Abstract
Many governments all over the world are trying to fulfill the second basic need of shelter of human being by the affordable quality housing. Roofing is an important part of building in structural, architectural and aesthetic point of view. Due to rapid increasing different types of industry as well as growing cities and population, thin shell profiled steel sheet roofing element are using for architectural and structural purpose. Its lightness, corrosion resistance, high strength-to-weight ratio properties make them attractive to engineer and architect. Nowadays, profiled steel sheet thin shell roofing element is used in buildings, stadiums, airports, and industrial factories and other architectural applications. Innovative shapes of roofs using profiled steel sheet can be used aesthetic and structurally efficient. The objective of this study is to investigate thin shell profiled steel sheet roofing element for architectural and structural context. An extensive lab testing and finite element studies on parabolic and doubly curve shape profile steel sheet roofing has been conducted. Mode of failure, load of ultimate failure and deformation–load performance of parabolic and doubly curve shape thin shell profile steel roofing is presented in this study. It is observed that the specimens tended to fail in the concave portion for curve portion of roofing. It was a great attempt to find out aesthetically pleasing as well as structurally efficient parabolic and double curve shape of shell roofing on the basis of present results. It is showed that parabolic doubly curve roofing element is suitable for architectural and structural point of views. So, those innovative shapes of roofs using profiled steel sheet can plays an important role and explore innovation idea for different construction industries.
