Tensile strength of glulam
WebIn the European standard for glulam EN 1194:1999 the strength values perpendicular to the grain are specified in dependence on the tensile strength and grading class of the used boards respectively. By consideration of the test results given in this. WebIn this study, we test the tensile mechanical properties of single- and two-ply laminated bamboo at various off-axis loading angles and laminate configurations. The data is then compared to micro-mechanical models for predicting modulus and strength of …
