ボラードの強度試験とその解析 : JIS型ボラードの改善研究

抄録

The strength of bollards used for mooring and towing is specified by JIS. But recently some examples of damage of bollards are reported from some shipyards and so it will be an interesting problem to know the actual ultimate strength of bollards both for builders and for ship owners. In view of the circumstances stated above, it was decided to have a better understanding on the standard for bollards by the Japanese Association of Marine JIS. Accordingly, in order to examine the strength of JIS type bollards full scale tests were carried out and the weak points of those were found out. Then several test bollards deemed to be of improved type were manufactured for trial and tested so as to get the data for the improvement of the weak points about JIS type bollards. This is the report about those test result.
