Abstract

Fabric-reinforced cementitious matrix (FRCM) systems for repair and strengthening concrete and masonry are another tool allowing engineers and contractors to effectively remove deficiencies, improve performance and prolong life of existing structures. FRCM is a composite consisting of one or more layers of cement-based matrix reinforced with dry fibers in the form of open fabric. Two significant documents were published in 2013 to provide manufacturers, designers and contractors with requirements and guidelines for the acceptance, evaluation, design and installation of FRCM. The first document is ICC-ES AC434 developed to provide guidelines for the evaluation of FRCM strengthening of concrete and masonry structural elements since the model building codes in the USA do not have requirements for testing and determination of structural capacity, reliability and serviceability of this class of products. AC434 establishes requirements for testing and calculations that can lead to the issuance of a product research report by ICC-ES. Such reports may be accepted by code officials, under Section 104.11.1 of the International Building Code as evidence of a product's building code compliance. The second document is ACI 549.4R-13. This guide addresses the history and use of FRCM systems repair and strengthening, their unique material properties, and recommendations on their design, construction, and inspection. This paper will first address the development of the "Code Requirements for Evaluation, Repair, and Rehabilitation of Concrete Buildings" recently published by ACI (ACI 562), its impact for the repair industry and its relationship to the model codes. Next, the paper will summarize and present the key features of AC434 and ACI 549.4R for testing and design of FRCM systems, as well as underlining differences and commonalties with the consolidated practice of FRP usage as outlined in ACI 440.2R and ACI 440.7R.
