I-Joists in Timber - Discussion of Current Design Practice and Implementation in Structural Analysis Software

Finnjoists or I-joists are optimized composite beams with an I-section made of timber materials, where the flanges are made of laminated veneer lumber (LVL) and the web of OSB. The cross-section elements are glued together. The components can be used as a beam or a column. In this bachelor thesis, the simplified design practice of the European Technical Approval ETA 02/0026, based on the limit internal forces, is compared with the more general design practice according to ÖNORM B 1995‑1‑1:2019, based on the limit stresses, and checked for consistency of the results.
