Design As - Detailing provisions

As was mentioned in the previous chapters there is also possibility to including detailing provisions during design routine. All settings related to detailing provisions are available in Concrete settings (structure) and in Manager of national annexes. Calculation of detailing provisions is dependent on member type. There are the following groups.

• Plate, Shell (Plate)
• Wall, Shell (Wall)
• Deep beam

All explanation of setting for detailing provisions for 2D members and activation of particular detailing provisions can be done in chapter "Concrete settings (structure)"

Reinforcement diameter for detailing provisions

Three different approaches of using reinforcement diameters in case of existence provided reinforcement or not are implemented

• Provided reinforcement is not used - diameters for detailing is used the same as for required reinforcement
• Provided reinforcement is used (but only basic)
  • diameters for required reinforcement is used from additional,
  • diameters for detailing reinforcement is used from basic reinforcement
• Provided reinforcement is used (both basic and additional)
  • diameters comes from basic or additional, depends on if A_s,stat ≥ A_s,basic or not

A_s,req is calculated as max(A_s,stat; A_s,det,min), where A_s,det,min is affected by A_s,prov,

All 2D members

Longitudinal

Check minimal clear bar distance 8.2(2)

Calculation of maximum allowed area of reinforcement from minimum clear spacing of reinforcement bars

Plate, Shell (Plate)

Longitudinal

Check minimal ratio of principal reinforcement 9.3.1.1(1)

Calculation itself is based on formulas from 9.2.1.1(1)

Check maximal ratio of principal reinforcement 9.3.1.1(1)

Calculation itself is based on formulas from 9.2.1.1(1)

Check minimal transverse ratio of secondary reinforcement 9.3.1.1(2)

Determination of principal or secondary reinforcement layer is defined via concrete member data

Check maximal spacing of principal and secondary longitudinal reinforcement 9.3.1.1(3)

There are different requirements for principal and secondary reinforcement

Shear

Check minimal ratio of shear reinforcement 9.3.2(2)

Check minimal thickness of member with shear reinforcement 9.3.2(1)

There is only message that there is small depth and should be increased to design also shear reinforcement

Check maximal spacing of shear links 9.3.2(4)

Wall, Shell (Wall)

Longitudinal

Check minimal ratio of vertical reinforcement 9.6.2(1)

Check maximal ratio of vertical reinforcement 9.6.2(1)

Check maximal spacing of vertical reinforcement 9.6.2(3)

Check minimal ratio of horizontal reinforcement 9.6.3(1)

Check maximal spacing of horizontal reinforcement 9.6.3(2)

Transverse

Check maximal spacing of shear links 9.6.4(1)

Check minimal spacing of shear links 9.6.4(2)

Deep beam

Longitudinal

Check minimal ratio of horizontal reinforcement 9.7(1)

Check maximal spacing of reinforcement 9.7(2)

National annexes are supported in detailing provisions. For more details about national depended values, see pdf document "National annex for EN 1992"
