Bearing capacity of deep locks of wooden rods
Abstract
Wooden rods, which usually have a wedge-slot construction and possess low weight, low cost, ease of manufacture, non-deficiency of material, are rarely used. The reasons for this are the low bearing capacity of the deep lock of such rods, not exceeding 1 -1,5 tons, short life and low resistance to shear forces...
