Stress Grading of Timber Joists

Stress Grading of Timber Joists comprises a technical manual, which contains details of the selection of a timber beam and setting up for a four point loading test. A set of three dial gauges is required to measure the curvature of the beam in the central region of constant bending moment.

Point loading is applied using the Dual hydraulic ram system. Stress Grading of Timber Joists system allows pressure to be applied simultaneously from one pump
