This article introduces the current methods for concrete floor slab solid testing and their applicability, as well as the methods for selection of testing data, calculation of load effect and calculation check- ing of limiting states related to concrete floor solid appraisal.

Based on related experiments research of RC beam strengthened with unilateral steel-slab-bonded and practical engineering needs,the technique of RC floor strengthened with bilateral steel-slab-bonded.

Technique of structures strengthened with near surface mounted(NSM) fiber reinforced plastics(FRP) is the effective solution for the difficulty caused by rough surface of negative moment regions of RC floor,which could mitigate the slab crevice.
