Bridge assessment provides a measure of adequacy of an existing bridge for current design loads. To determine the load carrying capacity of the bridge it is necessary to have a complete idea of the bridge’s present condition as well as if any modification is done to the bridge since it was built. The load rating proofs to be a key tool for bridge assessment.
The emphasis in load rating is on the live-load capacity and the approach of determining rating factors instead of the design approach of satisfying limit states. Load Rating for bridges is done at both the strength limit state and service limit state.
Assessment process as per CS 454
- Introduction to CS454
- Consideration of Live Loads for Assessment
- Assessment Verification in midas Civil
Key point 1: Introduction to CS 454
CS 454 is the newly introduced standard used for the Assessment of highway bridges and structures. Through this session we would like to shed some light on this new code and how it can be used to assess the structural safety and serviceability of highway bridges
Key point 2: Consideration of live loads
Assessment live loads is classified into two in CS 454:- All Model 1& All Model 2. Either of these two models can be used. In this session we will understand the assessment process as well as see where and how ALL Model 1 and ALL Model 2 vehicle to be used to get most critical effect on the bridge.
Key point 3: Assessment verification in midas Civil
The CS 454 specifications for the bridge assessment have been implemented in the current version of midas Civil. In this session we will see how assessment of PSC/PSC composite bridge can be carried out in midas Civil.
