Post-Fire Damage Inspection of Concrete Structures - Phase III - In-Situ Experimental Phase

项目名称：	Post-Fire Damage Inspection of Concrete Structures - Phase III - In-Situ Experimental Phase
摘要：	Massachusetts Department of Transportation (MassDOT) has experienced several recent tunnel fires, as reported in recent MassDOT reports. Post event evaluation of damage has been difficult due to insufficient information and protocols. A better understanding of post-event condition is needed. The current project will complement efforts which are underway in the second phase of this research program. In short, Phase I provided a thorough literature review, development of a draft inspection protocol checklist, and evaluation of a heat system for physical testing, while Phase II provides results from a laboratory experimental program where concrete panels (and some tunnel non-structural components) are tested. Phase III will modify the heating set up developed in Phase II for in-situ heating and field verification of existing structural elements being removed from service. This will allow for field results that include in-situ moisture content and thermal conductivity to verify results from the laboratory tests, as well as proof of concept for using the heating set up in field testing. Testing will only be completed on components that are scheduled for demolition or removal, and are expected to include both tunnel (wall or panel elements) and bridge components (deck, abutment or pier).
