The compression tests were conducted with the load of 18,000kN that was 10 times more than the connection load for the purpose of breaking a full-sized material, and it did not result in destruction. Moreover, it was confirmed that the rubber gasket, presently manufactured in Japan, have enough endurance under the hard condition in repeating load. Thus, it can be used without fear in the practical construction. |
