Abstract

This chapter delves into the evolution of bridge analysis methods, focusing on the development of the Ontario Highway Bridge Design Code (OHBDC). It begins by defining key terms and concepts in bridge analysis, such as load distribution and bridge deck types. The text then explores various analysis methods used in the late 1960s and early 1970s, including computer-based methods like the finite element method and manual methods like distribution coefficient methods. The chapter highlights the work of influential figures like Leslie G. Jaeger and the development of the OHBDC, which aimed to simplify bridge analysis while maintaining accuracy. It discusses the concept of the factor D and its application in the OHBDC, as well as the differences between the OHBDC and AASHTO specifications. The text also covers the development of simplified methods of analysis for the OHBDC and the further refinements made in the 1983 edition. Finally, it pays tribute to Dr. Leslie G. Jaeger, a mentor and friend to the authors, who played a significant role in the development of the OHBDC.
