Table 3: Damage state definitions and spectral displacement for HAZUS Macro-seismic Approach (HMA) and Capacity Response Approach (CRA) displacements.

Damage State	Description(Hazus)	HMA Roof Disp. (mm)	CRA Roof Disp. (mm)	Difference (%)
D1	Slight Structural Damage: Flexural or shear type hairline cracks in some beams and columns near joints or within joints.	30.48	26.66	14.3
D2	Moderate Structural Damage: Most beams and columns exhibit hairline cracks. In ductile frames some of the frame elements have reached yield capacity indicated by larger flexural cracks and some concrete spalling. Non ductile frames may exhibit larger shear cracks and spalling.	60.96	76.66	-20.5
D3	Extensive Structural Damage: Some of the frame elements have reached their ultimate capacity indicated in ductile frames by large flexural cracks, spalled concrete and buckled main reinforcement; non ductile frame elements may have suffered shear failures or bond failures at reinforcement splices, or broken ties or buckled main reinforcement in columns which may result in partial collapse.	182.88	228.33	-19.9
D4	Complete Structural Damage: Structure is collapsed or in imminent danger of collapse due to brittle failure of non ductile frame elements or loss of frame stability.	487.68	350	39.3
