Fredrik Lagerström 1.1 6 The design of members with shear reinforcement is based on a truss model (see figure below).

11
12 α is the angle between shear reinforcement and the beam axis,
13
14 θ is the angle between the concrete compression strut and the beam axis perpendicular to the shear force,
15
Fredrik Lagerström 4.1 16 F,,td,, is the design value of the tensile force in the longitudinal reinforcement,
Fredrik Lagerström 1.1 17
Fredrik Lagerström 4.1 18 F,,cd,, is the design value of the compression force in the direction of the longitudinal member axis,
Fredrik Lagerström 1.1 19
Fredrik Lagerström 4.1 20 b,,w,, is the minimum width between tension and compression chords,
Fredrik Lagerström 1.1 21
Fredrik Lagerström 2.1 22 z is the inner lever arm. In shear analysis without axial force, the approximate value z = 0.9 d may normally be used.
