2011 off the Pacific Coast of Tohoku Earthquake, gymnasium buildings exhibited
the unexpected structural damages, which prevented a use as evacuation shelters
in during- and post-disaster periods.

during the emergent inspection. According to the earlier studies, it was
implied that the presence of the slotted hole possibly deteriorates the seismic
capacity; however, the length of slotted hole was fixed at a certain value.
Facing this concern, this research attempts to clarify the influence of the
slotted hole length through a comprehensive parametric study by pushover and
seismic response analyses. In conclusion, it has been discovered that the
slotted hole deteriorates the seismic capacity for the connection failure up to
almost 50% of that without slotted hole. Moreover, the discrepancy of
characteristics obtained by the static and dynamic analyses is originated by
means of the presence of slotted hole. This slotted hole effect should be noted
by structural engineers and researchers to provide the adequate seismic
diagnosis and strengthening.</span></span></span>
