Reliability analysis of concrete girder bridges using measured statistical data

초록

Reliability analysis for a proposed limit state bridge design code is performed. In order to introduce reliability concept to design code, the proposed live load model is based on truck weight survey. Test data of domestic material strengths are collected to model statistical properties of member strengths. Sample RC and PSC girder sections are designed following the proposed code and compared with the current design practice. Reliability index is calculated for flexural and shear strength and the proposed code is concluded to provide reasonable level of reliability compared to international design standards.
