Buckling of Oil Storage Tanks in SPPL Tank Farm During the 1979 Imperial Valley Earthquake

摘要: An oil storage tank that suffered damage during the 1979 Imperial Valley earthquake is studied using a laboratory model. The unanchored and includes floating roof. subjected to single horizontal axis base excitation. Buckling under both harmonic simulated motion. model buckling results are in reasonable agreement with field observations. It was also found roof has no effect on behavior. Comparison API design provisions shows empirical used as basis of code for tip-over bucking have little resemblance actual
