Fctm of concrete
Webfctm,ax = 0.3 (f fck) 2/3 (N/mm2) (1) 1. INTRODUCTION The design of steel fibre reinforced concrete accord-ing to the σ-ε-method is based on the same fundamen-tals as the design of normal reinforced concrete. The proposed method is valid for steel fibre concrete with compressive strengths of up to C50/60. The European pre-standard ENV 1992-1-1 WebThe characteristic compressive strength fck is the first value in the concrete class designation, e.g. 30 MPa for C30/37 concrete. The value corresponds to the characteristic (5% fractile) cylinder strength according to EN 206 …
