Prevents local damage like excessive cracking or deformation during normal use to ensure a long lifespan. 3. Establish Material Properties and Loads

Controlled cracking permitted under peak service loads; design relies on crack width calculations similar to reinforced concrete. 6. Practical Implementation and Software Workflows
This article is intended as a technical summary. Always consult the original British Standard documents for legal and contractual purposes.
Check compressive and tensile working stress limits, perform explicit crack-width calculations, and check structural deflections. Prevents local damage like excessive cracking or deformation
Tensile stresses are allowed, but they must not cause cracking.
The design compressive strength of the concrete is taken as:
