Canvas Tent Shelters on Wood Frames,

None of these stations was in evi-

dence at the time of inspection except station 65 at Teiteiripucchi. This
station was still intact except that the ridge member was broken about to
inches back from the face edge. All canvas had been removed before the
tests. These stations were used for work and storage space during the

period of test preparation,

Design was adequate for the purpose intended.

Station 7 - Wood Frame Structure.

The station at the tower southeast

of Runit was removed prior to this inspection.
It is understood that the
structure suffered no damage, The structures inspected were not damaged,
The Piiraai structure showed a "belly-in" of about one-half inch of the

face-on wall, but there were no cracks in studs, sill, or plate.

Stations 8 and
- Reinforced Concrete Bases with Steel Frame, There
was no damage to these structures on Engebi (Sites 5 and Bt), Design is
considered adequate,
As was expected, Station 8 at Aomon was severely damaged. The collimator block was blown apart, the base was badly broken up, and the steel
framing was badly bent. There was no damage to Station 9 in the Aomon
Group. Design is considered adequate,
Station 10
- Reinforced Concrete Base with Steel Frame. Station 10
on the Aomon ‘Group was partially damaged. The collimatorblock and base
were not damaged, The tie down rods were strained and bent; the steel

frame was buckled about one inch; and the limonite blocks hung on the collimator for additional protection were shattered. However, it is understood that all data was obtained.

Station 10 was undamaged at all other sites,
Station11 - Reinforced Concrete Base with Steel Frame.

of failure was anticipated for all Stations ll.

Some form

The collimator block at Station 11 on Runit was blown off the base
because of failure by shear and elongation of the tie down rods (U-bolts).
The design is considered adequate.

At Station’ 11 on Engebi, the 10 inch by 1 inch steel plates welded

together to form.an H-beam buckled about one and one-quarter inches at
midspan; two tie down anchors on the lagoon side were broken in tension,
The block remained in position on base.

At Engebi (E+), Station 11, the block was blown off its base; tie
down anchors were not in evidence, and the steel frame was buckled.
The collimator block and steel frame at Station 11 on Aomon were
completely gone, There was one section of a collimator block lying about

500 feet southeast of the structure, and it was assumed that this was

part of the installation,

There was no evidence of the rest of the
