dc.description.abstractStructural reliability was examined on the lesser-used timber species such as Akomu (Pycnanthus angolensis) and Eriri (Vitex doniana) which can be good substitute to the well-known species. The strength and physical properties of these timber species were determined to predict their suitability as structural material. Forty lengths of timber species of 50 x 50 mm cross-section were purchased from timber markets in Ilorin, Kwara State, Nigeria. The prevailing environmental conditions during the test were 31 oC and 64 % relative humidity. The properties tested were air dry density, moisture content and compressive strength parallel to grain of forty test specimens each of lengths, 200, 400, 600 and 800 mm in accordance with the British Standard BS 373 (1957). Mean air-dried moisture content for Akomu and Eriri were 11.12 and 13.29 %, respectively. Mean density of Akomu and Eriri were 644.58 and 889.84 kg/m3, respectively. The typical derived equations to relate the stress and strain for Akomu and Eriri were y= 1097.8x − 2.9858 and y = 1033.7x − 2.5309, respectively. Results of reliability analysis show that Akomu and Eriri timber have reliability index of 0.68 and 0.63, respectively for a service life of 50 years, provided other serviceability conditions are met.en_US
