Starting from December 2000, a timber research was initiated in the Faculty of Civil Engineering, Universiti Teknologi Malaysia (UTM), under the IRPA grant no. 72214 until May 2003. During the research, bending, tension and compression tests were conducted on structural sized DRM timber specimens in accordance with ASTM standard (D 198-84) procedures [1]. A new stress model was also proposed to predict the ultimate bending strength of DRM timber beams. Then, the model was verified by using the experimental results of bending, tension and compression tests. Ultimate tensile and compressive strengths of test specimens were the input parameters in the model. During bending tests, the distribution of strain in mid-section wood fibres, the ultimate load, and the deflection of beams were recorded. The ultimate load and the values of strains at certain load levels were recorded during direct tension and compression tests. Moisture content and density of test specimens were also determined according to ASTM D 4442-92 [2] and D 2395-83 [3] procedures.
