Abstract:
The physical and mechanical properties, safe working stresses for structural uses and suitability indices for different end uses were determined for 6 Bhutan timbers, viz. Abies densa, Juniperus recurva, Picea spp., Pinus wallichiana, Populus ciliata and Tsuga dumosa. Comparisons made between these species from Bhutan and from elsewhere in the Himalayas found no significant differences in their properties
