摘要：
The use of near surface mounted (NSM) fibre reinforced polymer (FRP) is a promising technology for increasing flexural strength of reinforced concrete (RC) members. This paper deals with strengthening of RC two-way slabs with NSM carbon fibre reinforced polymers (CFRP) rods. The first part describes an experimental investigation conducted on RC two-way slabs strengthened with NSM CFRP rods. Test results show that the NSM technique improves the bearing capacity of RC two-way slabs. A comparison with a test results on RC tow-way slab strengthened with externally bounded (EB) strips is also presented. In the second part, a 2D finite element model for orthotropic plates is used to describe elastic behaviour of RC slabs strengthened with NSM CFRP rods. Elastic behaviour is compared to numerical prediction. (c) 2007 Elsevier Ltd. All rights reserved.
