Width of cross-section for shear check

There are calculated two widths for shear check

• value b_w – this value is calculated as the smallest width of the cross-section in tensile area of cross-section perpendicular to direction of resultant shear force. This value is used for calculation shear resistance of concrete (V_Rdc) according to clause 6.2.2(1)
• value b_w1 – this value is calculated as minimum width of cross-section between tension and compression chord perpendicular to direction of shear force. These values are used for calculation:
  • design value of maximum shear force VEd,max (calculation without reduction β), clause 6.2.2(6)
  • design value of maximum shear force limited by crushing of the compression struts (V_Rd,max), clause 6.2.3(3,4)
  • design value of shear force carried by shear reinforcement (V_Rds), clause 6.2.3(3,4)
