• Test connections taken form a damaged steel frame (building demolished).
• Test in existing condition to evaluate residual strength.
• Repair connections using recommended procedures and retest.
• Use 3D Nonlinear analyses to estimate connection loading.
• Use nonlinear finite element analysis to predict force vs. displacement (hysteresis) curve and stress strain distributions.
• Perform hardness surveys across connection and cut tensile coupons from webs and flanges of specimens.
