Standard Test Method for Conducting Traverse and Concentrated Load Tests on Panels used in Floor and Roof Construction
SIGNIFICANCE AND USE
Transverse Load—The procedures outlined will serve to evaluate the performance of floor and roof segments for deflection, permanent set and ultimate capacity. Performance criteria based on data from these procedures can ensure structural adequacy and effective service.
Concentrated Load—This concentrated load test shall be used to evaluate surface indentation of structural framing members.
These procedures will serve to evaluate performance of roof and floor segments under simulated service conditions. Diaphragm shear loading of roof and floor segments shall be evaluated under Test Method E 455. Impact loading shall be evaluated under Test Methods E 661 or E 695.
SCOPE
1.1 This test method covers the following procedures for determining the structural properties of segments of floor and roof constructions: Section Test Specimens5 Loading6 Deformation Measurements7 Report9 Precision and Bias10 Testing Floors Transverse Load11 Concentrated Load12 Testing Roofs Transverse Load13 Concentrated Load14
1.2 This test method serves to evaluate the performance of floors and roofs panels subjected to (1) Uniform loading, and (2) Concentrated static loading, which represent conditions sustained in the actual performance of the element.

5. Test Specimens
5.1 Specimens—There shall be at least three replicate specimens for each test. Specimens shall be constructed to represent
sections of the floor, or roof assembly including the means of the attachment when the load direction is away from the supports.
The specimens shall be representative in width and length as to the material and workmanship. The test specimen shall not be less
than the width and length of the tributary load area under actual conditions. If the tributary load area for the test specimen exceeds
the test equipment, a reduced specimen that is representative in proportional width and length shall be tested. Unsymmetrical
assemblies shall be tested in each axis. If the structural properties of a particular construction are to be compared with another
construction, widths of the specimens shall be of comparable size.
5.2 Age—Constructions, which include concrete and masonry for which the structural properties depend upon the age of the
specimen, shall be aged not less than what is indicated by the manufacturer and/oror national standard, or both. The age of the
specimen shall be recorded in the report.
6. Loading
6.1 Apparatus—The testing machine or load-measuring apparatus shall comply with the requirements prescribed in Practices
E4.
6.2 Application of Load—Apply the load to each individual specimen in increments so that a sufficient number of readings will
be obtained to determine definitely the load-deformation curve (see 6.3) using the following sequence:
6.2.1 Prior to testing, apply a small initial load not greater than 5 % of the ultimate capacity load expected and hold for 5 min
(6 1 min) and then release. Zero all measuring devices and begin the test.
6.2.2 Record the initial load and deformation reading of the specimen and then increase the load on the specimen to the first
predetermined increment.
6.2.3 Record the load and deformation reading and release the load back to the initial load and then record the set of the
specimen.
6.2.4 Increase the load to the next predetermined increment and record the information as indicated in the first load increment
above. Follow this sequence of loading and reading for all predetermined load increment(s).
6.3 Duration of Load Application—After each increment of load is applied, maintain the load level as constant as possible for
a period of 5 min (see Note 1).Take deformation readings as soon as practical after load application, at the end of the 5-min period
under constant load, and immediately and at the end of the 5-min period after any partial or complete load release. Plot initial and
5-min readings in the form of load-deformation curves. Maintain complete load-deformation time records throughout the test. If
application of a given load is required for a certain period, such as 24 h, take deformation readings at the end of this period, to
allow the satisfactory plotting of a time-deformation curve for the complete period.
NOTE 1—Reason for the 5-min application of constant-level increment loads are as follows:
(1) To permit the assembly to come to a substantial rest prior to taking the second set of readings. (Depending on the method employed for applying
the test load, it may be necessary to continue, at a reduced rate, the motion of the loading device in order to maintain the constant load level during the
5-min period.)
(2) To observe any time-dependent deformation or load redistribution, or both, and to record accurately the load level when time-dependent
deformation starts, that is, at the divergence of the immediate and delayed load-deformation curves. This load level may, under certain conditions, have
an important bearing on the design load.
(3) To be able to stop the test, if this should be desirable, prior to total failure, after initial failure has been anticipated as a result of the observations.
(4) To assure uniformity in test performance and consistency in test results.
7. Deformation Measurements
7.1 Measure the deformations with sufficient precision to define the load-deformation relationship, and report at least to the
nearest 0.25 mm (0.01 in.). mm.

8.1 Prepare the report in accordance with Recommended Practice E 575.

10.2 Apparatus—The apparatus shall be capable of applying a uniform load (such as air bag load or vacuum load), gravity load
or two point load and shall conform to the requirements prescribed in 10.2.1 through 10.2.3 or the equivalent.
10.2.1 Uniform Load—Uniformly distributed loading is a satisfactory test method. Uniformly distributed load shall be applied
by air pressure, either in a bag or in a vacuum chamber.

loaded and wider than the specimen to the supports by tie rods. Place an airtight bag as wide as the specimen and as long as the
span between the specimen and the reaction platform.Apply transverse load to the specimen by increasing the air pressure in the
bag. Measure the difference in pressure by means of a manometer or other pressure measuring device. The error of the pressure
reading shall not exceed 1 % of the full-scale reading. Deflection measurement shall be measured following 10.4. See Fig. 1.
10.2.1.2 When the vacuum chamber method of loading is used, place the specimen near the test frame to create an airtight
vacuum chamber. An airtight frame or curb shall surround the specimen closely and be flush with the upper surface of the
specimen. An air resistant blanket covers the specimen, overlaps the frame, and is sealed so that it is reasonably airtight. Use a

10.2.2 Gravity Load—Gravity load testing shall be conducted in accordance with Practice E 196.
10.2.3 Two Point Load—The two point (quarter-point) loading method is used for transverse load tests. Test the specimen as
a simple beam (Fig. 3) on a span 150 mm (approximately 6 in.) less than the specimen length. Apply two equal loads, each at a
distance of one-quarter of the span from the supports, toward the middle of the span. For floor specimens tested horizontally (Fig.
1), the load on the specimen shall include the weight of the specimen between the supports.Apply the transverse loads to the upper
(finish floor) face for three of the symmetrical specimens. For asymmetrical assemblies, the bottom face for three of the specimens
must also be tested. Deflection measurements shall be measured following 10.4. See Fig. 3.
10.3 Loading Application—The application of load is found in 6.2. The application of load shall be compatible with the test
apparatus indicated in 10.2.
