Allowable Uniform Load Tables
Full section 3-point bending tests were conducted on Treadwell Reinforced Plastics’ H-Beams, I-Beams, C Section and Square Hollow Section. The allowable uniform load tables were generated using these tests results as well as the formulas, properties, and assumptions listed below. Formulas for critical buckling and lateral-torsional buckling developed from theory are presented in Chapter 6 and 7 of the ASCE Structural Plastics Design Manual.
