摘要

This paper presents the results of loading tests regarding RBS moment connection with staggered hole alignment developed for use in rehabilitation and upgrading of existing non-ductile moment frames. Major findings obtained from loading tests are as follows: 1) fractures initiated from the toe of a weld access hole is prevented; 2) method to evaluate the flexural strength of RBS with staggered hole alignment on the bottom flange are suggested and its varidity is confirmed.
