Analysis of the Residual Safety Level in RC Slabs with Severe Joist Corrosion
Publication: Journal of Performance of Constructed Facilities
Volume 29, Issue 4
Abstract
An analysis until the failure on a series of one-way slabs with severe corrosion at the lower reinforcement of the RC joists is presented. Different positions in the slab and number of damaged joists have been studied, obtaining the residual safety assessment in cases of slabs damaged by flexural failure mechanisms. Since the boundary conditions have proved decisive for obtaining the behavior, the damaged slab has been evaluated as part of the entire building, as precisely as possible, taking into account the different phases of the construction process and deterioration in time, and the complex behavior of concrete, steel and masonry. The results of the proposed methodology are consistent with the pathology of the observed cases. As a result of this study the authors propose practical recommendations to help in making decisions about the magnitude of the intervention, always necessary in this type of pathology.
