Mechanism, Design Theory and Structural Reliability of
Corrugated Arch Metal Roof
Abstract: Based on the experiments of the full-sized model and from the degrees of theory research and actual application, this paper does the research work on mechanism, design theory and structural reliability of corrugated arch metal roof systemically. Verified and justified by the full-sized model, we offer the theory and methods to the people to design it and its value of application.
From the degree of theoretical analysis, the paper offers the finite element theory of orthotropic thin plate, deduces the relations between the waves and the orthotropic plates, and influence factors to them. It truly reflects the influence to stress and strain state, and the bearing capacity of CAMR, offered by the waves.
On the basis of research of mechanism, and combined the design with the construction of CAMR, we reach the experimental formula for the supporting and internal forces, bearing capacity, deformation of CAMR. Based on the full-sized experiments and actual projects, we analysis the actual state of stress and strain state during the construction, and offer some comments on the design and construction of CAMR. By the statistical principles, we get the index of structural reliability of CAMR. In the light of the developing history and tendency of modern spatial structures, we form the embryo of the branch between spatial structures and bionics.
