Synopsis
A clear, data-driven look at how structural timber performs in the real world.
This nonfiction presents a program of timber tests conducted by the Bureau of Forestry to uncover the mechanical and physical properties of commercial timbers. It explains how test results inform design rules, grading, and inspection, while exploring practical questions about species, growth, and treatment.
The book lays out the scope of the testing program and the stations and researchers involved. It describes how large sticks from real markets are tested to reveal how wood behaves under load, moisture changes, and processing. Readers will see how data from different regions and species are collected, interpreted, and used to improve safety and economy in construction.- How strength relates to knots, grain, and growth rate in common timbers
- Comparisons across species like loblolly pine, red gum, red fir, and western softwoods
- How moisture, seasoning, and preservatives affect performance in design and practice
- What tables and figures reveal about modulus of rupture, elasticity, and strength under various conditions
