Reliability Assessment System In Reinforced Concrete Structures

The function of structures will certainly deteriorate with time under environmental effects. A systematic analysis so-called life-cycle reliability management including construction stage, normal used stage, and aging stage should be used for a particular structure.In the present thesis, following the baseline of the assessment and prediction for existing structures, based on the previous research contribution on Reliability Assessment in Structural Engineering (RAISE-7), a new software RAISE-8 to assess and predict the reliability of existing reinforced concrete structures has been accomplished with CAD technology.The most work done in the thesis is to introduce how to use CAD technique,VBA and data-base to develop a new software RAISE-8. The work focus on the following three aspects:1) Use CAD technology and add five kinds of blocks in autocad to record and inspect member's information.2) Use VBA technology to read blocks information and output them to extent data files.3) Based on RAISE-7, some subroutines have been modified for the steel corrosion model in concrete.4) The new software has been validated by practical projects.
