摘要

Shell structures are used popularly due to aesthetic and economical use of materials. The objective of this paper is to develop self-supporting roofing system with simulates deflection and stress-strain behavior of different types of roofing element by finite element techniques. The experimental investigation confirms the validity of the nonlinear finite element analysis. Conventionally, metal sheet such as zincalume is using in roof as covering materials. A self-supporting roofing system where sheeting roofs runs continuous lengths of roof sheeting from one end to other end support eliminating internal support. An attempt has been made to find out efficient, economic and aesthetically pleasing shape of thin shell zincalume elements to provide self-supporting roofing system on the basis of present results. The load—deflection, stress-strain and deflected shape profiles of investigated roofing element showed that parabolic roofing element having crown height 1/6 of chord length was more efficient than others.
