Structural behaviour and application of cylindrical composite wooden tubes [1.86 mb]
Zusammenfassung (Englisch)

The purpose of this research is framework to explore the probability and superiority of applying xylindrical composite wooden tubes in practice. The ultimate target is to utilize sustainable material in an efficient and reliable way. Whole research framework begins from literature review, which provides a universial perspective on the developing history and structural behavior of engineered wood. Subsequent research consistspf a series of study and comparison about composite tubes. By comparing, Michaelis formula is proved to be more conservative and feasible for assessment of the behavior of composite tubes. All comparison, studies and discussion hereinafter depends on the appraisal results form Michaelis fromula. With the assistance of evaluating formula, the capacity and expected failure modes of a variety of tubes are predictable. This research then plots advisory tables according to the estimated results plus a security factor. Advisory tables offer an avenue for users to adopt tubes in buildngs. Furthermore, an application of the assigned tubes is carried out to verify that they are serviceable in an architectural project. It is demonstrated that these tubes are competent for this multi-storey structure. A comparison about self-weight of vaious constructions is then executed. This framework testifies that tube-based buildings possess lower self-weight, which elucidates that this construction comprises structural and economical efficiency. In the end, this research conceives a methodology to find out the optimal profile for tubes subjected to certain axial load. This invention precipitates the ultimate target.
