WATER IMPACT LOADS ON STRUCTURES

Abstract

Theoretical and experimental investigations were made of responses of spherical shell structures subjected to water impact loads. Effects of structural flexibility were evaluated and a simple mathematical model for predicting dynamic loads in a spherically shaped structure was developed. Six model tests were conducted; qualitative agreement was obtained between the theoretical and experimental results. Theoretically predicted coupled responses of the model and water were observed in the test results. The theoretically predicted response frequencies averaged 20 percent above the measured frequencies. Predicted acceleration levels averaged 10 percent lower than the experimentally determined values.
