Case study of condition assessment and structural audit of fire damaged building
For most fires occurring in buildings with a concrete structural frame, the structural elements don't collapse during fire exposure, and further use of the building after fire could also be possible. Fire can nevertheless end in a permanent loss of strength and thus a post-fire evaluation of the residual load bearing capacity has got to be made to tell decisions on continued use and therefore the need for structural repairs. This present study is based on several NDT methods, how to use and apply them with recommending following solutions. As in this case several NDT methods are used such as Ultrasonic pulse velocity test, Schmidt rebound hammer, pH and chemical test, Cover meter test, Half-cell potentiometer test and the Extraction of core samples and testing them which gives enough reliable data to recommend the solution as in this case recommended RC column jacketing with is design and detailing to retain the mildly damaged area and demolish some part of the structure which is very critical to stand.
