연속합성형교의 비탄성평가방법의 개발에 관한 연구 = A Development of Inelastic Rating Method of Continuous Composite Steel Girder Bridges

다국어 초록 (Multilingual Abstract)

It has been known that inelastic design of steel girder bridges can result in beneficial material and fabrication cost savings and reduce the susceptibility of steel girder bridges to fatigue. The ability to redistribute large negative region moments, coupled with section capacities exceeding the yield moment, results in an efficient structure used to its limit-state capacity. But until now the method calculating the redistributed moment at pier section is very difficult. It is necessary to simplify the way to determine the redistribute moment at pier section. This paper presents simplified method to determine final redistributed moment without repeating calculation.
Most important thing of all in elastic rating of continuous composit I-type bridges is to determine the redistributed moment. Using coefficients used to determine allowable ultimate bending stress and redistributed moment calculated by previous inelastic method some relationship between these could be found and more simplified method to determine redistributed moment will be found.
