Figure 14: The pushover patterns for 10-story steel buildings. For 10-story buildings, hybrid achieves 82% damper damage concentration versus 58% column damage in bare frames. In 15-story cases, hybrid maintains 76% damper hinging protecting frame elements (18% damage) against 72% column damage in bare frames and mixed brace/column damage in brace-only systems. The hybrid bracing system demonstrates clear superiority in plastic hinge distribution analysis across all building heights. In 5-story buildings, bare frames exhibit extensive beam and column hinging indicating soft-story vulnerability, while brace-only systems concentrate damage in braces and damper-only systems show scattered damage across structural elements, but the hybrid localizes damage
