Why Talk about SFRC?
The design of steel fiber reinforced concrete (SFRC) structures is becoming more popular. It is beneficial to structural engineering to combine traditional reinforcement with SFRC (hybrid solution), the design will become more robust (more ductile), and the traditional reinforcement and/or the concrete cross-section can be decreased. The ductility also increases shear and punch force capacity significant.
The fib Model Code 2010 describes different constitutive laws which can be used to check your design with SFRC. Both simplified laws as more advanced laws are included. In the upcoming fib Model Code 2020 these different laws are now coupled to levels of approximation (LoA) and advise you to either use cross-sectional analysis for the lower LoA’s or use Finite Element Analysis for the higher LoA’s.

Why Join us for this Session?
For Finite Element modelling the constitutive law is often applied in a smeared crack approach - good guidelines used to be lacking. We discuss the fib Model Code 2020, an update of the advanced constitutive model for SFRC which has been added in order to improve the behavior.
We will go into detail about improving crack localization - good crack localization is very important with the smeared crack approach.
Professor Marco Di Prisco will take us through the general assumptions and the lower level of approaches in a way that engineers can directly take advantage of their daily jobs. Pim van der Aa will guide us through the background and setup of Finite element analysis including the material characterisation.

Pim van der Aa
Pim van der Aa (MSc) graduated from Eindhoven University of Technology in the faculty of Built Environment, specialized in Structural Design.
During his master thesis project, he investigated the pull-out behavior of a single steel fiber by means of finite element analysis.
He works as a structural/civil engineer at the Consultancy Department of DIANA FEA BV for more than 7 years.
