Reasons for Reaves

Reason number 1:
We sell a totally engineered building.

With a totally engineered building, qualified & experienced suppliers put their resources together to create a reliable product. Some of the partners coming together for Reaves are Component Manufacturing Company, and Robbins Engineering. We also use Engineering Technical Services for in-plant inspections, design certification and quality control.

Twin City Testing & Engineering Laboratories, Inc. compared rack load capacities on different roof and wall panels. The wood braced shear walls in the Reaves Building System outperformed the tie-rod braced and cable braced shear walls of typical metal buildings.

Subject: Wind Load Testing
Class 30, 60 & 90 Roof Assembly
UL Standard 580
#6600 88-003.3

Report #7-11737 presents the results of Reaves roof assembly wind testing according to Underwriters Laboratory Standard 580 for Class 90 roof assemblies. The purpose of our work was to load the roof assembly according to the UL Standard 580 to determine whether or not the assembly meets this standard. Based on the results of our testing, the Reaves roof assembly using corrugated channel drain, Channel drain 2000 and Panel drain which is manufactured by Wheeling Corrugated Company, exceeds Underwriters Laboratory Standard 580 for Class 90 roof assemblies.

Based on test results, the Reaves roof assembly qualifies for the UL-90 uplift test according to UL Standard 580. For specific information pertaining to Reaves roof assembly and type of steel, nailing, etc. refer to Twin City Testing report #7-11737.

Test #6600 88-003.3

Subject: Load Testing
Prefabricated Roof Panels
Reaves Building
Sioux Falls, South Dakota
#6600 88-003.3

Introduction
This report presents the results of our load testing on the prefabricated roof panels that we performed on the Reaves building. The purpose of our work was to load test the roof panels in accordance with The Uniform Building Code. Our work was performed at the verbal request of Mr. Lloyd Reaves of the Reaves Corporation on March 8, 1988.

Conclusions
Based on the results of our observations and load testing, it is our opinion that the prefabricated panels will withstand the following loadings with a minimum ultimate strength factor of safety of at least 2. The 2" x 4" x 8' -0" panel (see attached drawing) is capable of a 50 pound snow load and an 8 pound dead load with a factor of Safety of 2. The actual deflection of the 2x4 panel was 0.27" at full snow load plus dead load. The 2" x 6" x 10' -0" panel is capable of a 40 pound snow load and an 8 pound dead load with a Safety factor of 2. The actual deflection at full live load plus dead load was 0.50".

Method of Test
The test specimens used were representative of the materials and workmanship in the manufacturing plant. For information on actual panel sizes tested, please see the attached drawings. Testing was performed in accordance with The Uniform Building Code. Each sample was loaded to 8 psf, released, and the permanent deformation or (set) was recorded. The samples were then reloaded to 8 psf dead load. Samples were loaded with the use of 6" x 12" concrete cylinders with an average weight of 29.2 pounds each.

Additional loads of approximately 5 psf increments were added until the desired live load was attained. During loading, the deflection was measured using dial indicators calibrated to 0.001 inches. Four dials were used on each panel. Then the overload was applied in 5 psf increments until overload reached two times the allowable loads. After loading was removed, all wood and nails were checked for any signs of failure. No signs of overstressing were noted.

Subject: Rack Load Testing for Prefabricated Roof and Wall Panels
Reaves Building
Sioux Falls, South Dakota
#66-9137

Introduction
This report presents the results of our rack load testing on the prefabricated wall and roof panels that we preformed on the Reaves Building. The purpose of our work was to rack load test the roof and wall panels in accordance with ASTM:E-72. Our work was performed at the verbal request of Mr. Lloyd Reaves of Reaves Corporation on April 5, 1984.

Conclusions
Based on the results of our observations during our rack load testing and the deflection readings, it is our opinion that the prefabricated panels will withstand the following loadings with a minimum ultimate strength factory of safety of at least 2 and will be limited by deflection up to L/180.

*Load allowable is based on ultimate strength divided by 2, or L/180, whichever is less.

Method of Test
The test specimens used were representative of the materials and workmanship noted previously in the manufacturing plant. Since the specimens were prefabricated, the total height of the specimen used in the testing of the wall panels was the highest wall using the smallest sized column as recommended for the Reaves Building. The width of the specimens was 8' wide, since all fabricated panels are of this dimension. For further information on actual panel sizes tested, please see the attached drawings.

Testing was performed in accordance with ASTM:E-72. Each sample was loaded to 800 pounds, released, and the permanent deformation, or "set" was recorded. The samples were then reloaded to 1600 pounds. Samples which did not fail at 1600 pounds were released, "set", recorded and loaded to failure.

The apparatus used for the load test of the wall and roof panels complied with ASTM:E4. It was a Black Hawk Hydraulic Pumping Ram unit calibrated by the use of a Lebow Model 7510 Transducer Digital Indicator, Serial #22.1, and a Lebow Mode 3632-50k Hollow-Core Load Cell, Serial #95.
