Abstract
This paper introduces three experimental research works on protective structures against bomb and blast loadings that
were directed by the late Professor A. Johoji, who was then a Colonel in the Fortification Headquarters of the old Japanese
Army before WWII. First, bombing tests for reinforced concrete (RC) buildings were performed in order to examine the
effects of reinforcement of the roof against aerial bomb attack. Second, blast loading tests for RC wall shelters were carried
out in order to investigate the effects of concrete depth and size of an RC wall against blast loading. Third, explosive tests
for various types of tunnel shelters were conducted to determine the effects upon corners in branch type and mesh type
tunnels under blast pressure.
