I am currently running a non-linear FEA (Using Lusas-Concrete Model 94) on a steel fibre self-compacting concrete (SFRSCC) slab.

I am having difficulties in getting similiar pattern for the load-displacement curve validation. I suspect its coming from the strain value. Currently using 0.0035 (typical normal concrete value).

With inclusion of steel fibres, i believed the sttrain value will need to be revised.

Appreciate anyone to share the value either from books/journals/experimental results.

Please and Thank You.
