Existing Joint Check

Check the beam-column joints capacity for existing building as per NTC2018 (Circolare)

From the Main Menu select Design > Design Result > Existing Joint Check

From 'Set Existing Joint Check Parameter' Dialog, select the load combinations/Show elements type/ Check position for which joint capacity check will be calculated.

Refer to Usage of Table Tool and check the following data:

 Existing Joint Check Parameters dialog box

Load Cases/Combinations

Select the desired load combination or All Combinations.

Existing Joint Check Table Type

Select the elements either showing the selected elements or all elements

Select Check Position

    Set the check position of beam-column joint

Existing Joint Check Tables

Element : Element number

Position : Output position to existing beam-column joint check (Top or Bottom)

Stress : Kinds of stress, Tensile stress and compressive

Load : Govern Load combinations for joint stress ratio

Demand : Demand stress, Tensile stress and compressive stress as per equations C8.7.2.11/12 Circolare NTC2018

Capacity : Capacity stress, Tensile stress and compressive stress as per equations C8.7.2.11/12 Circolare NTC2018

Remark : If the 'Demand/Capacity' exceeds 1.0, 'NG' is printed, otherwise 'OK' is printed.

Note. Use Tips
1) This check option is activated only with NTC2018 codes.

2) If 'Apply Special Provision for Seismic Design' of concrete design code is active, this check option can't be activated.

3) This check must be performed only for 'Not Confined Joint' as defined in 7.4.4.3 of the NTC2018 codes.

4) When 'No Beams' is displayed in remark field, it means there is no joint with the beams. so there is no meaning to review.
