A Neural-Wavelet Technique for Damage Identification in the ASCE Benchmark Structure Using Phase II Experimental Data

Table 2

Damage cases and quantified damage metric (Γ_ASCE) based on experimental description of damage in ASCE benchmark structure.

Structure Configuration	ΓASCE	Damage class
(1) Fully braced	0	Healthy
(2) All braces removed from East face	28.4	PD
(3) Braces removed on all floors in SE corner	21.3	PD
(4) Braces removed 1 & 4 floors, SE corner	8.5	PD
(5) Removed braces on E & N faces (2nd floor)	31.2	PD
(6) Braces removed all floors and all faces	85.1	FD
(7) Config. 7 plus loosened bolts N & E face	100	FD
(8) Config. 7 plus loosened bolts N & E face (1st & 2nd floors)	91.1	FD

E: East, SE: South-East, N: North, PD: Partially Damaged, FD: Fully Damaged. ^∗Γ_ASCE is evaluated using (1).
