This paper is intended as an investigation of the mechanical behavior of wooden single-layer space frame by numerical analysis. The constructional elements of wooden structures are divided into the timbers, bolted joints and joint of steel plates. These elements are treated as beam elements with various mechanical properties. The validities of these elements are verified by comparing the analytical results with the experimental results on the single-layer lattice domes in ref. 17). Next, the calculation formulas for mechanical properties of bolted joints are derived. The effects of joint properties estimated by using the calculation formulas on mechanical behavior of wooden single-layer space frame are examined. Furthermore, dealing with the wooden space frame with gymnasium size, the effects of the occurrence of slip at joints on the mechanical behavior of space frame are investigated.
