Design With Confidence
Barchip’s macro synthetic fiber concrete reinforcement conforms with international design methodologies and standards from bodies such as DBV, RILEM, CNR, ACI, ITAtech and the UK Concrete Society.
Our experienced team can guide you through the design process, providing comparative analysis, structural design and where appropriate complex finite element analysis (FEA). When you design with Barchip, you design with confidence.
Background information on the use of macro synthetic fiber reinforced concrete is given in; The UK Concrete Society’s TR 65 – Guidance on the use of Macro-synthetic FRC, April 2007.
Designing Industrial Floors
The majority of industrial floor slabs using fiber reinforced concrete are designed in accordance with;
The UK Concrete Society’s TR 34 4th Edition – Concrete Industrial Ground Floors – A Guide to Design and Construction March 2016
American Concrete Institute ACI 360.R-10 Guide to Design of Slabs-on-Ground.

Sprayed Concrete (Shotcrete) for Mining and Tunnelling
Barchip’s fiber reinforced sprayed concrete is typically designed based on its energy absorption requirements or the moment capacity of the structure. Common guidelines include;
Barton’s Q-system (left)
American Concrete Institute ACI 506.1R-08 Guide to Fiber- Reinforced Shotcrete
Concrete Institute of Australia Shotcreting in Australia 2nd Edition.
More complex situations can require N-M interaction diagrams to analyse the moment capacity of the structure. For more information, download;

For special cases Barchip’s experienced team can provide detailed finite element analysis (FEA) for our synthetic fiber reinforced segments, which prove performance over the entire life of the structure.
Commonly, N-M interaction diagrams are used to analyse the moment capacity of cast-in-place final linings. Barchip’s experienced team can also provide detailed FEA for special cases.

Designing Precast Concrete
Precast concrete elements are often complex structures. Their design usually follows national concrete codes. If designs exist with steel reinforcement Barchip can provide structural analysis using moment capacity and performance requirements.
For specific applications Barchip can prove the performance of the structure using detailed FEA and predict crack width and crack propagation, shrinkage, creep and fatigue performance.
Testing of Fiber Reinforced Concrete
The energy absorption capacity of Barchip’s fiber reinforced concrete is measured according to internationally recognised standards. Common tests for sprayed concrete are;
ASTM C 1550 Standard Test Method for Flexural Toughness of Fiber Reinforced Concrete
EN 14488-5 Testing sprayed concrete – Determination of energy absorption capacity of fiber reinforced slab specimens
EFNARC Panel Test
General test methods for fiber reinforced concrete are;
ASTM C 1609 Standard Test Method for Flexural Performance of Fiber-Reinforced Concrete
EN 14651 Test Method for Metallic Fibered Concrete
JSCE-SF4 Method of Tests for Flexural Strength and Flexural Toughness of Steel Fiber Reinforced Concrete
