Design Methodology

Abstract

In this final part of the present work, the gained experiences from previous parts of this work on paperboard laminates are transferred to a construction design process. First, an introducing part with an overview on the current challenging aspects on standardization in terms of building with paper are discussed. The focus is mainly set on the mechanical properties. Building physical design aspects like e.g. fire retardation, humidity and biological impact prevention etc. are not considered. The discussion of standardization challenges is followed by a general view on differences between current testing standards on mechanical properties of paper materials and of conventional construction materials. Further, decisive parts of Eurocode 3 as a current timber construction standard are taken into account and related to experiences with paperboard laminates. As a main part of the construction standards, the partial safety factors are introduced and a potential safety application method on the paperboard laminates for design purposes is suggested. Also, the corresponding laminate in-plane failure criterion is adapted. Further, a simplified criterion is suggested to enable easily accessible application possibilities. Finally, yield stress determination methods are presented as alternatives to the material strength values which were, used for establishing the in-plane failure criterion.
