Book Description
This report presents updated design guides for both thick- and thin- walled concrete cylinder structures under hydrostatic loading. The design approach for thick-walled cylinders has been changed from that described in previous work to a semi-empirical basis; improvements in implosion strength on the order of 10% are found. A test on a thick-walled 10-ft-diam (3.05-m) structure loaded to failure in the ocean is reported. A major change in the guide is for thin-walled cylinders, where new data on 15 relatively large-scale specimens are reported. Design guides for thin-walled cylinders show an increase in implosion strength ranging from 0% to 35%, depending on the structures' tDo and L/Do ratios, from that reported previously.
