Scientific Research An Academic Publisher. Any applicable errata are included with individual documents at the time of purchase. The proposed guidelines are based on the knowledge gained from experimental research, analytical work, and field applications of FRP systems used to strengthen concrete structures.

FRP systems offer advantages over traditional strengthening techniques: Design Optimization of Reinforced Concrete Frames. These items are not eligible for return.

Moreover, the observed failure was that of the fracture of the FRP strips for all such specimens. Debonding of the FRP strips or failure of the anchoring device results, as was to be expected, 440.2e-08 relatively unsatisfactory FRP material exploitation.

Choose Product Language English. This document offers general information on the history and use of FRP strengthening systems; a description of the unique material properties of FRP; and committee recommendations on the engineering, construction, and inspection of FRP systems used to strengthen concrete structures.

Errata are not included for collections or sets of documents such as the ACI Collection. The highest degree of FRP material exploitation was achieved in the specimen that utilizes a patented anchoring device together with two layers of SFRP strips. A novel loading arrangement was utilized to apply the necessary forces to these unit beam specimens together with instrumentation capable of capturing the behaviour of these specimens up to failure.

Studying in this way the transfer of forces from the open hoop FRP strips, it could be demonstrated that when this type of retrofitting was accompanied with a properly designed anchoring device, a significant increase in the bearing afi of the tested specimens was observed. The full and complete returned product will qci accepted if returned within 60 days of receipt and in salable condition. FRP strengthening systems use FRP composite materials as supplemental externally bonded reinforcement.


Due to the characteristics of FRP materials as well as the behavior of members strengthened with FRP, specific guidance on the use of these systems is needed. ManosAck V. For a listing of and access to all product errata, visit the Errata page.

Fiber-reinforced polymer FRP systems for strengthening concrete structures are an alternative to traditional strengthening techniques, such as steel plate bonding, section enlargement, and external post-tensioning.
