DEVELOPMENT OF PROBABILISTIC MODELS FOR RESISTANCE AND LOAD EFFECTS FOR THE BRIDGE DESIGN CODE . BRIDGE ENGINEERING WORKSHOP; PROCEEDINGS; 14TH ARRB CONFERENCE, 28 AUGUST - 2 SEPTEMBER 1988, CANBERRA

Probabilistic models for structural resistance and load effects have been constructed using available data. This paper discusses the lack of sufficient data to adequately describe the complete probability distribution. The statistical parameters of strength and load effects are used to compute safety indices for the ultimate limit state for bridge superstructures. The load effects considered are due to dead load and traffic live load, the predominant bridge superstructure loads. Safety indices have been computed for prestressed concrete members designed to the existing naasra bridge design specification and also in accordance with the draft bridge design code in limit states format. The draft code has achieved a more uniform level of reliability but shows some inconsistency between the different spans (a). For the covering record of the workshop, see IRRD no 814823.
