“…Other important issues which should be developed in the analysis of double corrugated arch structures include elastic buckling, non-linear buckling and post-buckling behaviour. The foundations of analytical deliberations on the issues are presented in papers [83], [84], [85], [86], [87], [88], [89] and [90]. Contemporary follow-up on their ideas is presented in paper [91], which applies to the testing of non-linear elastic in-plane buckling and post-buckling parabolic arches in reference to analytical numerical solutions.…”

Double corrugated, self-supporting K-span arch structures are now commonly used globally to make roofs for building structures, as an alternative to traditional solutions. The K-span system has become popular mainly due to the simple and cheap method of its manufacturing and quick installation. Nowadays, new versions of the system are created but still there is no valid design method. Design difficulties are among the causes of failures or even collapses of such structures. Back in the 1970s, the first studies were developed concerning computational analyses of double corrugated arch roofs. They laid grounds for the development of contemporary K-span system technology but have since lost their practical advantages due to changing engineering conditions. The paper presents a review of research and computational methods concerning double corrugated arch structures. The paper discusses selected scientific studies, which were used as the basis for the development of research and computational methods, and their contemporary continuation. Directions for further research and analyses are also presented which could contribute to the future development of science and engineering in the area and could provide inspiration for future studies.

“…We follow the Reissner±Mindlin model to consider shear deformations and use the assumed strain method (Dvorkin and Bathe, 1984) to alleviate shear locking problem. In order to model stiffened structures, we also consider section eccentricity neither to use the rigid links (Jiang et al, 1997) nor to introduce dummy layers (Stiftinger et al, 1995). We solve several numerical examples to show the effectiveness of the proposed element for geometrical non-linear shell structures.…”

This paper presents a simple stress resultant 4-node shell element for geometrical non-linear analysis. In order to model smooth surfaces and/or stiffened structures, a simple and ef®cient technique for ®nite rotation is adopted. By means of suppressing the component of singular rotation effectivley, convenient use of six degrees of freedom is possible without deteriorating the robustness and the convergence rate of the classical 5-dof formulation. In the formulation of shell element, section eccentricity is also considered to model stiffened structures. Through numerical experiments the effectiveness of the proposed method is demonstrated.
