AbstraktThe paper describes the structural project for a timber cantilevered walkway truss recently built in Vitoria-Gasteiz, Spain, as part of a Nature Explanation Building Center. This study analyses the structural aspects of this walkway, designed as a cantilevered truss with a span of 19,2 m and a backspan of around 10 m between the two lines of columns of the structure.
The structure has been built mainly using Laminated Veneered Lumber (LVL) for the struts and chords and steel bars for the diagonals. The critical sections, at the two lines of columns, have been built using frames made of steel and reinforced concrete. Due to the critical tension force that appears at the foundation, permanent anchors were used for transferring this force to the ground. Wind loading has also lead to anchoring the two pairs of concrete columns. The joints in the timber trusses were designed using dowels with steel gusset plates and toothed rings.
The basis for the analysis and design has already been described in . This paper adds mainly detail construction aspects.
