ideCAD automatically designs beam-column joints in accordance with ACI 318-19.
Notation
h = overall thickness, height, or depth of member, in.
The shear resulting from moment created by gravity load, wind, earthquake or other lateral forces at beam-column joints should be considered in the design of the joint.
According to ACI 15.2.6, if a column extension provides continuity through a beam-colum joint in the direction of joint shear, it considered shall satisfy the following two conditions:
The column extends above the joint at least one column depth, h, measured in the direction of joint shear considered.
Longitudinal and transverse reinforcement from the column below the joint is continued through the extension.
According to ACI 15.2.7, if a beam extension provides continuity through a beam-colum joint in the direction of joint shear, it considered shall satisfy the following two conditions:
The beam extends at least one beam depth h beyond the joint face.
Longitudinal and transverse reinforcement from the beam on the opposite side of the joint is continued through the extension.
According to ACI 15.2.8, for a beam-colum joint to be considered confined for the direction of joint shear, two transverse beams should be satisfed the following three conditions:
Width of each transverse beam is at least three-quarters of the width of the column face into which the beam frames
Transverse beams extend at least one beam depth h beyond the joint faces
Transverse beams contain at least two continuous top and bottom bars satisfying ACI 9.6.1.2 and No. 3 or larger stirrups satisfying ACI 9.6.3.4 and 9.7.6.2.2.
