Estimation of Design Thermal Loads on PSC Box Girder Bridges by Statistical Extrapolation of Analytical Data

해석 데이터의 통계적 방법을 통한 PSC 박스거더교의 설계 온도 하중 추정

This paper describes the procedures to estimate for the design thermal loads on prestressed concrete box girder bridges on th basis of the extreme analysis of the temperature data obtained from long-term thermal analyses. Long-term thermal analyses using the environmental data for three years were conducted, and the extreme distributions of th thermal loads are then determined by the tail-equivalence method, and the thermal loads corresponding to selected return period are calculated. Finally, the results are compared to the specifications suggested in a current design code for thermal loads.
