Abstract
In this paper, report on the structural design of a timber two directional parallel chord truss, which limited the material, section and length. And report about it mock-up loading experiment. The timber-truss was applied to the roof at Gojo gymnasium in Nara of Japan. Until the second floor was a reinforced concrete structure, the roof was a hybrid structure of steel and timber-truss. The plane of the arena was a long axis about 56.8m, short axis about 50.8m. Keel beam and four sides of the roof was a steel frame. And others were covered with timber-trusses. As for the truss, the unit of T-type comprises a top chord wood and a web, the units rotate a direction 90 degrees and are jointed, and a bottom chord intersects perpendicularly and is jointed to the web of the unit.
