The relationship between torsional rigidity and bending strength characteristics of SA pine
Item type: Journal Article • Journal: The Southern African Forestry Journal • Authors: W. M. G. Burdzik [d849458e21] P. D. Nkwera --- Department of Civil Engineering,The modulus of rigidity, G, and bending moment ofelasticity, MOE, of SA pine are evaluated from a direct torsion test and bending tests. Specimens were subjected to a series of tests with the view to determining direct torsional rigidity, apparent... -
Strength and stiffness capacity utilisation of timber members in roof truss structures
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: C Brand Wessels --- Department of Forest and Wood Science, South Africa Nils-Olaf Petersen --- Department of Forest and Wood Science, South AfricaThe main objective of this study was to determine which property, of the six strength and stiffness properties used in structural timber design, was the most influential in the design of nail-plated roof trusses. Thirty recently completed nail-plated roof truss... -
Investigation of green-glued laminated timber from the Congo Basin: durability, mechanical strength and variability trends of the bondlines
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: René Oum Lissouck --- University of Yaoundé I, Cameroon Rachel Raïssa Ngono Mvondo --- Institute of Wood Technology, University of Yaoundé I, Cameroon François René Ateba --- Institute of Wood Technology, University of Yaoundé I, Cameroon Regis Pommier --- University of Bordeaux, FranceThe development of glulam may give complementary, added-value to an important part of the timber production in the Congo Basin. Nevertheless, the high humidity in which these timbers operate may cause problems such as cracks and severe deformations if they...
