RESEARCH OF PARALLEL CHORD TRUSSES WITH DIFFERENT ANGLES OF DIAGONALS USING RESIDENTIAL TIMBER

The purpose of this study is to create and verify the performance of large-span parallel chord truss as a design case for medium- to large-sized timber structures. In this paper, the authors carried out the bending tests on full-size truss and validated them with elastic analysis models. The experimental results showed that the yielding of the steel used in the joints plasticized the trusses. In addition, the design criteria were satisfied by applying the uniformly distributed load to an analytical model simulating the truss.
