A honeycomb girder (HCG) is defined by a mirror symmetric arrangement of two trapezoidal corrugated steel sheets (TCSS). Mechanical fasteners such as screws or rivets connect them. The high bending stiffness of HCGs provides the opportunity to span distances up to 14.0 m. Especially in the application as a cladding of roofs and facades of industrial steel-framed buildings this new construction type promises the potential to improve the resource and economic efficiency of these buildings. Former experimental investigations verified a numerical model. Based on this finite element method (FEM) model a parametric study on HCGs with an equidistant fastener arrangement has been carried out. By applying three design criteria on the numerical results the maximum characteristic surface loads for 360 HCG constellations have been determined. This paper investigates the influence of a graduated arrangement of mechanical fasteners in HCG systems on their maximum characteristic surface load.
Optical methods are now often used in the measuring technology. These methods have the great advantage that the inspected objects are measured contactlessly with a high repetition rate. The obtained data can be evaluated in almost real-time or in post-processing. This allows the reckoning of deformations in real-time, as well as the three-dimensional representation and the documentation of the whole process of deformation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
