WOODEN BRIDGE

DATA
File may28a_freq_mode.mat includes data matrix of size 261 x 2008

261 variables
2008 measurements

Variables:
The first 9 variables are natural frequencies
The rest are 9 complex mode shapes scaled using one sensor. There were 15 sensors.
Therefore, the dimensionality is 9 x [1 + 2 x (15-1)] = 261

Measurements:
1-1880 undamaged
1881-1900 Damage 1
1901-1923 Damage 2
1924-1945 Damage 3
1946-1965 Damage 4
1966-1985 Damage 5
1986-2008 undamaged

The damage scenario is a point mass on the top girder
D1: 23.5 g
D2: 47 g
D3: 70.5 g
D4: 123.16 g
D5: 193.66 g
