SAFETY INDICES FOR VARIOUS LIMIT STATES OF STRESSED TIMBER DECKS

In the past, several deterministic models for stresses and deformations have been developed to design stressed timber bridges; however, safety indices for various limit states have not been established because of the absence of field data. Utilizing limited field data, this article establishes safety indices for serviceability limit states such as deflection, human response, and cracking of wearing surface, stress limit states, and timber fatigue limit state. For example, a safety index of 2.5 is suggested for stressed deck bridges with resistance factors ranging from 0.5 to 0.8, and load factors ranging from 1.5 to 3.8.
