A s1 = Total area of the tensile reinforcement placed on one side of the column-beam node to accommodate the negative moment of the beam
A s2 = Thetotal The total area of the tensile reinforcement placedon placed on the other side of thecolumn-beam node withrespectto with respect to A s1 to accommodate the positive moment of the beam
b j = In the earthquake direction considered, if the beam stuck in the joint area is the same width as the column or protrudes from both sides of the column, the column width, otherwise, twice the distance from the vertical middle axis of the beam to the column edges (the beam width cannot exceed the sum of the height of the junction)
b w = beam width of the body
f ck = concrete characteristic cylindrical compressive strength
f yk = resistance to flow characteristic of longitudinal reinforcement
h = cross section dimension in the earthquake direction Considering the Column
V e = column, beam, combination of and taken as a basis shear of transverse reinforcement accounts curtain
V Arm = Thesmaller The smaller of the column shear forces calculated according to Section 4 above and below the node point
ϕ = Reinforcement diameter
