IV. Results of the study
The summary for the 1st year study is as follows.
1. Collect pre-study data and identify study scope
Pre-study data were reviewed and design package for similar projects were also reviewed.
-Domestic and international technical reports were reviewed and similar study results were compared
-Design packages for similar study were reviewed and the process and economy study were performed
2. Identify performance upgrade method and process development model
Numerical analysis was performed for railway steel plate girder bridges for various girder length and various total bridge length. The structural safety for PC-slab composite plate girder was reviewed. The drafts for design specification and maintenance guide specification were developed. The design package was prepared for field test and this test would be performed for Sukkyochun Bridge locates at Shinyeemoon station in Kyungwon line. The test would be performed in June 2010 with the supports of Korea Rail Corporation and Korea Rail Network Authority.
3. Test model development and fabrication
Using a 7 m PC-Slab, which was fabricated by КС Industrial Development, PC-Slab composite plate girder bridges were fabricated and the performance test was performed. The full scale test was performed for 2 plate girders which were purchased from Korea Rail Network Authority. From this test, the performance upgrade for PC composite plate girder was verified.
4. Field test
Currently, the test is being coordinated with Korea Rail Corporation and Korea Rail Network Authority. The design package includes technical reports were prepared and the contract with the company who is performing the test was signed.
