“…The influence of corrugation depth and radius of curvature of profiles on their mechanical properties has been discussed in [1,11]. The shape of cross section investigated in [11] varies from the one considered in our paper, but the analysis of the results obtained from numerical calculations and standard [10] gives the valuable insight into the limitations of the latter.…”

“…The shape of cross section investigated in [11] varies from the one considered in our paper, but the analysis of the results obtained from numerical calculations and standard [10] gives the valuable insight into the limitations of the latter. It showed satisfying correlation for plain-walled profile; however that was not a case for a curved profile with corrugated wall.…”

Abstract. The paper presents problems related to the numerical modeling of profiled steel sheets used as self-supporting arch structures for roof covering. The rules of preparing and full analysis of a set of numerical models of these elements with a different level of complexity are given. The models are evaluated by comparing numerical results with the results of extended experimental tests performed by 3D Digital Image Correlation (DIC) method. For each model the comparison of numerical and experimental results has been made for samples of a single-wave trapezoidal profile with corrugated web and lower flanges subjected to compression and bending. The full-field analysis allows to determine the allowed simplification of numerical models which do not affect in significant way the reliability of the results. The proposed methodology is the first step in the development of full assessment methodology for different types of self-supporting arch structures produced by ABM technology.

A novel method for shaping innovative building forms, roofed with diversified complex continuous and discontinuous folded structures composed of many transformed corrugated shell units, is presented in the paper. The units are defined on the basis of specific reference polyhedral networks and arranged on arbitrary reference surfaces characterized by the negative Gaussian curvature. The method is presented using several computer models of complex building structures with folded plane-walled elevations. The proposed method significantly supplements the previous method developed for modelling building free forms, roofed with shell structures arranged in conformity with surfaces having the positive Gaussian curvature. Some basic rules using parameterization and governing the creation of the multi-plane elevations, ribbed continuous and discontinuous roof shell structures, arranged in different unconventional and visually attractive patterns, were developed. The elaborated specific sets of division coefficients are taken as parameters for the designed building structures. These sets determine unconventional polyhedral networks, which are composed of several specific sets that allow to define a polygonal eaves network, a reference surface and, finally, individual shell units of the roof structures. The developed method is presented using the example of three novel forms defined by means of the appropriately selected diversified sets of values of the division coefficients. The elaborated new forms confirm the innovative nature of the achieved results. By imposing appropriate proportions between the values of these division coefficients, the developed method enables the creation of two different groups continuous and discontinuous complex shell roof structures.

“…In recent years, a number of researches were carried out to study the behavior of arch-shaped steel sheet sections, including the work of Cybulski et al, who studied the influence of surface transverse geometric imperfections called corrugations on the local stability of cold-formed elements and two types of thin-walled elements are considered: a panel with smooth walls and panels with corrugations on their surfaces. Finally, the conclusions are made, which can be useful for design purposes [5][6]. Piekarczuk and Malowany have worked on the comparative analysis of numerical models of arch-shaped steel sheet sections.…”

The modern basic civil engineering concept is to design simplistic structures, by using innovative brand new manufacturing and assemblage concepts. As a result of this concept, arch type steel plates are used like the corrugated coatings. The main purpose of this work is to describe the Roll Form Machine (RFM) technology as used for the structures, especially for the roofs. Cold formed arch type steel structures may be fast and simple. These types of structures were used for temporary buildings in the US Army. Nowadays, this technology becomes popular and gets in consideration for civil life. However, the design concept of this technology does not have a theoretical model, and the calculations are evaluated according to the United States Standards. The uniaxial compressive behaviors of corrugated arch type steel members are observed, experimentally within this work.
