- Abstract
- Alternative approaches are reviewed for revision of the original NBS preliminary performance criteria for tensile strength and tensile fatigue strength of bituminous membrane roofing. Reviews of five approaches - elasticity theory, brittle fracture, viscoelasticity theory, strain energy and finite element techniques - were completed. Advantages and limitations of these approaches were identified and use of the strain energy approach for both tensile strength and tensile fatigue strength preliminary performance criteria was recommended.
