Abstract

Crack distribution and Extension is the important mechanical features of flexural members strengthened by carbon fiber sheet bonded with inorganic adhesive after fire, which is helpful to understand all-round mechanical performance of the style of structural members. Four strengthened beams and four strengthened slabs are tested, and their crack development with loading increase is recorded in detail. The test and analysis results show that, For beams strengthened by carbon fiber sheet bonded with an inorganic adhesive which experienced fire, bending cracks are obviously more than bending and shear cracks, which is because that temperature of lower area of beam section is higher than that of upper area. CFS has a role of restricting crack production and development. The more CFS is, the bigger crack width is and the smaller crack distance is.
