PSC 합성거더교의 온도차에 관한 해석적 연구
An Analytical Study on the Temperature Difference of PSC Composite Girder Bridge
- 발행 : 2006.05.11
초록
The temperature difference of deck and girder is one of the major factors that affect the stress distribution of a section, and therefore, the design of a composite girder bridge. However, domestic design codes of highway and railway bridges, respectively, present different shapes of design equations regarding the temperature difference, which may induce some confusion to the designers. In this study, each design equation is investigated on a theoretical basis and compared together. Some other methodologies such as finite element method and other equations from a different point of view are also taken into account for further comparison. An example of a railway bridge is presented to verify the result of each scheme.
