WOODEN BRIDGE

DATA
File may28a_freq_mode_wood.mat includes data matrix of size 232 x 2008

232 variables
2008 measurements

Variables:
The first 8 variables are natural frequencies
The rest are 8 complex mode shapes scaled using one sensor. There were 15 sensors.
Therefore, the dimensionality is 8 x [1 + 2 x (15-1)] = 232

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 (between sensors 1 and 2)
D1: 23.5 g
D2: 47 g
D3: 70.5 g
D4: 123.16 g
D5: 193.66 g

File may29_freq_mode_wood.mat includes data matrix of size 232 x 2148

232 variables
2148 measurements

Variables:
The first 8 variables are natural frequencies
The rest are 8 complex mode shapes scaled using one sensor. There were 15 sensors.
Therefore, the dimensionality is 8 x [1 + 2 x (15-1)] = 232

Measurements:
1-2000 undamaged (from which most are the same as in may28a_freq_mode_wood.mat)
2001-2019 Damage 1
2020-2042 Damage 2
2043-2065 Damage 3
2066-2091 Damage 4
2092-2114 Damage 5
2115-2148 undamaged

The damage scenario is a point mass on the other top girder (left from sensor 4)
D1: 23.5 g
D2: 47 g
D3: 70.5 g
D4: 123.16 g
D5: 193.66 g
