BIM and Forensic Structural Engineering: strengthening and repairing a post-tension concrete slab bridge

摘要

The forensic engineering investigation carried out to determine the possible causes of cracking in arnpost-tension concrete slab bridge and the rehabilitation proposed is explained in this paper. Thernfollowed methodology includes new technologies making up a complete BIM model in LOD 400 with allrnthe reinforcements and post-tensioning tendons and exporting it to Advanced FEA software in order tornanalyze and investigate the causes of the cracking.
