Development of the ontario highway bridge design code 1979

The report is a record of notes made for a verbal/ visual presentation made in April 1980 at arrc to a selected group of bridge designers and researchers who are, or are likely to be, involved in the production of an Australian limit states bridge design code. Methods of design generally used in ontario during the period 1950-1979 are briefly outlined. Reasons for adopting a limit states design format and the problems associated with its development and resulting advantages are given. Organisation and function of the committees formed to produce the lsd code are detailed together with the planned time schedule for the development of the code to the implementation stage. The necessity for a wide involvement of researchers and designers is emphasised as well as the importance of precise, meaningful codes which lack ambiguity. The code described was developed for the design of bridges of the types most commonly designed in Canada (made of steel, concrete and wood) and having a span less than 125 m. The code considers the statistical variability of resistances and loads, including soil, foundations, materials used, live loads, environmental loads, etc. The development of load factors and safety index ( =3.5) Is discussed. The guidelines the Canadian committees used in the development of the lsd code and for determining design safety and serviceability criteria are given.
