THE DESIGN ENGINEERING OF GRC ELEMENTS MUST RESPECT THE UNIQUE CHARACTERISTICS OF THE MATERIAL
Over the last two decades we have seen many GRC projects where the design and engineering principles have been based around incorrect assumptions of how the composite behaves, mode of collapse and consequences of failure.
Whilst many design engineers will look towards BS EN 1990/1991 these do not address many of the unique characteristics of GRC as a composite material.
In 2010 the International Glassfibre Reinforced Concrete Association (GRCA) published its “Practical Design Guide”. This used nearly 40 years of experience adopting an approach of factoring design loads up whilst also allowing for variations in properties of handmade products and the effect of ageing on flexural strength.
We can provide an independent third-party review of designs to ensure that best practices appropriate to the material are followed and allowed for.
