Table 4 Joint shear strength of test specimens.

From: Structural Performance of PC Double Beam–Column Connection Under Gravity and Seismic Loading

Specimen fc (MPa) Aj (mm2) γ Vjn (kN) Vju (kN) Vjn / Vju
SRC 40.5 298,200 1.2 2277 1216 1.87
SPC1 40.3 383,400 1.2 2921 1031 2.83
SPC2 40.3 383,400 1.2 2921 1025 2.85
  1. fc = concrete compressive strength, Aj = effective joint shear area, γ = a coefficient addressing the confinement effect of beams framed into joint, Vjn = joint shear strength (Eq. 6), Vju = joint shear demand (Eq. 7).
