CHAPTER Il, SECTION 3 PARTICIPATION: 22 CONSTRUCTION: 4-2-56/4-24-56 OCCUPANCY: 4-18-56 These stations were rehabilitated CASTLE Stations 311.02, 312.02 and 312.05. Gage mounts were furnished and installed by the User. STATIONS: PURPOSE: SITE: 160.01 and 161.01 Drag Response Station Yvonne USER: DOD-1 PARTICIPATION: 24 CONSTRUCTION: 1-25-56/4-21-56 Figure 2-49. STATIONS: PURPOSE: SITES: Stations 151.02 and 152.04 65% Complete 152.01 thru 152.04 and 153.01 thru 153.04 Drag Response Stations Man-Made Island, Able and Dog USER: DOD-1 PARTICIPATION: 18 CONSTRUCTION: 2-18-56/4-20-56 OCCUPANCY: 4-20-56 These stations were two 12-inch flanged columns 3’-6” high with steel plate members, used for supporting User-furnished I-beam and L-iron members. The 152 station series were for I-beams, and the 153 series were for L-irons. The steel columns were embedded in a pile- supported concrete foundation which was 6’ x 14’ x 2’ for the 152 station series, and 6’ x 10’ x 2’ for the 153 series. Cable was run back to a recording station for instrumenting the beams and angles. The average concrete poured was approximately 9 cubic yards for each of the series 152 stations, and 8% cubic yards for the 153 series. STATIONS: PURPOSE: SITES: 154.01 thru 154.12 Drag Response Stations Yvonne, Sally, Peter and Roger USER: DOD-1 PARTICIPATION: 22, 2 and 24 These stations were two User-furnished 4- ton jeeps at each location. One jeep faced, and the other was side-on, to ground zero. STATIONS: 155.01, 156.01 and 156.02 PURPOSE: Pressure versus Time and Velocity versus Time Uncle SITE: USER: Page 2-64 DOD-1 Each station consisted of five different models for supporting User-furnished specimens of various shapes and weights. Eight-inch steel pipes of lengths varying from 3’-6” to 5’ were embedded in 3’x3’x2QY concrete foundations to support the specimens approximately 3 above grade. It was necessary to weld the pipes to the reinforcing steel in order to maintain good alignment and elevation while pouring the concrete (57 cubic yards). STATION: PURPOSE: SITE: 162.01 Instrument Shelter Yvonne USER: DOD PARTICIPATION: 24 CONSTRUCTION: 1-16-56/4-16-56 This station was a one-room 8’ x 18’ 8’ high reinforced concrete structure which had 1’-6” thick walis and was used for housing the recording instruments of Stations 160.01 and 161.01. The south wall had a 4’-6’x 9watertight blast-resistant door for access. A wooden partitioned room within the station was utilized for battery storage. Because the structure was exposed to blast pressure from several directions, the founda- tion slab was extended beyond the walls so as to pick up the pressures acting downward, which would tend to resist overturning the building from side loads. Since the station was located near the lagoon shoreline, it was also necessary to build a riprap retaining wall for the floor slab. Power to the station was supplied from the island distribution system through a primary oil switch to a 45 KVA transformer and then to a 12-circuit breaker power panel at 120/208 volt, 3-phase, 4 wire, 60 cycle. The circuit brea- ker panel was located in the interior of the station. A 14’x 14’ tent and a trailer receptacle located outside the station were fed from this panel. User-furnished and installed batteries provided signal power at H minus one minute. A vapor-proof light fixture was installed in the
