ACI STRUCTURAL JOURNAL TECHNICAL PAPER Title no. 100-S7 Seismic Behavior of Nonseismically Detailed Interior Beam-Wide Column Joints—Part II: Theoretical Comparisons and Analytical Studies by Bing Li, Yiming Wu, and Tso-Chien Pan The experimental results of four full-scale reinforced concrete interior with the emphasis on the effect of joint transverse reinforce- beam-wide column joints with nonseismic detailing and limited ments, column axial load, and bond condition on the joint’s seismic detailing have been presented in the previous paper.

The developed finite element models were described and verified using the results of the experimental RESEARCH SIGNIFICANCE results presented in the previous paper. The global behavior and The seismic behavior of beam-column joints is influenced the principal stresses of the interior beam-wide column joints were by many parameters. Due to the inherent complexity of the discussed and examined in detail. The calculated results indicated joints, the effects of t
