Banjar traditional house architectural had been identified by symbolization that was emphasized on roof truss structure, ornamental style, decorative and symmetrical. Since 1871-1935 Banjar traditional house had been populer in Borneo people environmental. Bubungan Tinggi was one of the famous Banjar traditional house. Considering the geometric and the durability of the material the roof truss structure of Bubungan Tinggi should be evaluated in strength design and buckling capacity. This research investigated the strength and stability of the Bubungan Tinggi roof truss structure by performing the numerical analysis that were based on finite element method. Several idealization had been developed in this research such in 2D truss and 3D solid element by conducting some numerical software analysis then to be compared. The direct symmetrical property had been involved by introducing the material nonlinearity. Furthermore in buckling analysis, the 3D solid had been run in eigen value analysis. The results showed that the Bubungan Tinggi roof truss structure strong enough for supporting the loads. The result also showed the chord of the roof truss structure had high vulnerability in buckling failure. More stiffener member had been recommended to avoid the buckling failure occurred immediately
