콘크리트 거더 교량의 중간격벽에 대한 구조실험

The role of intermediate diaphragms in concrete girder bridge was studied by structural tests about 1/2 scale model of the typical design. The purpose of this research is understanding of the role of intermediate diaphragms which has been misused by vertical load distribution and misunderstood by design specification . Experimental variables included : location and number of intermediate diaphragms which were made by reinforced concrete or steel. Service load was applied the structure under static loads. Numerical analysis of the test bridge using solid element of finite element method was verified by comparison with the experimental results. Based on the results, in no case was an appreciable reduction in terms of vertical deflection.
