Abstract

Fibre reinforced concrete is a composite material that is increasingly used in construction practice. An often-discussed problem regarding the fibre reinforced concrete is the crack development state and post-cracking behaviour. The paper compares the calculations done according to the Eurocode design and calculations done according to the older procedure given by ČSN standard. The calculations are also compared with the calculations done using the SCIA Engineer software. From the obtained results, the complexity of the calculation, the amount of coefficients, and the variance of value given the current standards is evident.
