Brief Description of Research Project
This project is for consideration of a) laboratory studies to demonstrate the ability of fabric-reinforced-cementitious-matrix (FRCM) to restore section loss in flexure and shear; b) study the FRCM system subjected to environmental conditions, and c) implement of three different strengthening systems into a field demonstration project in coordination with the Missouri Department of Transportation. This project is undertaken with the partner university Univ. of Miami. The overall objective of this research [which includes round robin work to be carried out at Univ. of Miami (UM) in addition to Missouri S&T work] is to evaluate existing methods of repair of bridge girders, subjecting a new FRCM system to environmental studies, and a practical field strengthening implementation project. UM work will develop guidelines for the best methods of evaluation and repair.
