The effect of superimposed load was more pronounced for joists with cut ends.
The effect of a superimposed load was larger for the floor system with cut joists than for the undamaged floor.
In the second study, data on the effects of magnitude and location of dead load superimposed on the floor system were limited, Nevertheless, these data sug gest that superimposed loads may be an important factor in the inspection and evaluation of in-situ floor systems.
To obtain stable, reproducible data, the superimposed load was held at 0.
In bending, or in tension, it is difficult to maintain a small enough superimposed load to prevent accelerating creep and loss of signal.
Wood Beam and Joist, 15'X 15' Bay, Superimposed Load
, 40 Lbs.
This superimposed load is caused by acceleration of the test specimen and test fixturing that are attached to the load cell.
Fixturing induced errors include changes in data due to specimen end effects, and superimposed loads due to fixture and specimen mass.
Superimposed Load, Includes: Composite steel beams with welded shear studs, composite steel deck, lightweight concrete slab reinforced with welded fiber fabric, sprayed fiber fireproofing on steel beams: $8.
Wood Beam and Joist, 15' x 15' Bay, Superimposed Load, 40 Lbs.
CIP Flat Slab w/Drop Panels 15' x 15' Bay 40 PSF Superimposed Load
, 12" Min.
Completed Stage Loads: When both cantilevered portions were joined together with closing segment, the superimposed loads
were applied on the structure.
