Título:
D7199 Standard Practice for Establishing Characteristic Values for Reinforced Glued Laminated Timber (Glulam) Beams Using Mechanics-Based Models
Descrição: This practice covers mechanics-based models for calculating characteristic values for the strength and stiffness of reinforced structural glued laminated timbers (glulam). The mechanics-based analyses shall account for the following: (1) stress-strain relationships for wood laminations and reinforcement; (2) strain compatibility; (3) equilibrium; (4) variability of mechanical properties; (5) volume effects; (6) finger-joint effects; (7) laminating effects; and (8) stress concentrations at the termination of reinforcement in beams with partial length reinforcement. This practice also provides for minimum physical test requirements to validate mechanics-based models. A minimum set of performance-based durability test requirements for reinforced glulams is also herein described. Additional durability test requirements shall be considered in accordance with the specific end-use environment.
