13-120-080 Tests.

   Tests of structural materials when required shall comply with the provisions of Sections 13-120-090 to 13-160-130, inclusive.

(Prior code § 69-5)

13-120-090 Test specimens.

   The selection and construction of all test specimens and the details of test procedure herein shall conform to the applicable standards of authoritative testing agencies and laboratories. All test specimens and construction shall be truly representative of the materials, workmanship and details to be normally applied in practice.

(Prior code § 69-5.1)

13-120-100 Tests of materials.

   (a)   When the strength, durability, weather- resistance and other qualities of a material necessary to the conditions of its use have not been established by accepted engineering practice, or are in reasonable doubt, tests shall be made as hereinafter provided.

   (b)   Tests of materials shall also be made where specifically required by the provisions of this Code.

   (c)   Materials, when required, shall be subjected to sustained and repetitive loading to determine resistance to fatigue, and to tests for durability and weather-resistance when applicable to the use of the material.

   (d)   When not otherwise required in this Code, the applicable standards and specifications of the American Society for Testing Materials shall be deemed accepted practice in the conduct of tests of materials, assemblies and systems.

(Prior code § 69-5.2)

13-120-110 Tests of structural assemblies.

   (a)   When a structural assembly is not capable of design by accepted engineering analysis, or when there is reasonable doubt as to its strength or stability, the safe load-bearing capacity of such structural assemblies shall be determined by tests acceptable to the building commissioner.

   (b)   Such tests shall simulate the loads and conditions of application to which the complete structure will be subjected in normal use.

(Prior code § 69-5.3; Amend Coun. J. 9-13-89, p. 4604; Amend Coun. J. 3-5-03, p. 104990, § 27; Amend Coun. J. 11-13-07, p. 14999, Art. II, § 1)

13-120-120 Conditions of acceptance.

   In evaluating the physical properties of structural assemblies, the structural requirements shall be based on the following conditions of acceptance:

   (a)   Floor, Wall and Roof Transverse Tests.

      (1)   Test Load. The test assembly shall sustain without failure, superimposed loads equal to two and one-half times the design live load.

      (2)   Deflection. Under design live load, the deflection shall be not greater than one three-hundred sixtieth of the span for plastered construction and one two-hundred fortieth of the span for unplastered construction.

      (3)   Residual Deflection. If the deflection is greater than the computed theoretical deflection after 24 hours under the total static test load, upon removal of the load the construction shall recover not less than three-quarters of the total test load deflection.

   (b)   Wall and Partition Compression Tests.

      (1)   Test Load. The assembly, both with and without window framing, shall sustain without failure, superimposed loads equal to two and one-half times the vertical design live loads.

      (2)   Recovery. After 24 hours under the static test load, and after removal of the superimposed load, the specimen shall recover not less than one-half of all vertical and horizontal distortion and strain.

   (c)   Wall Racking Tests.

      (1)   Test Load. The assembly shall sustain the design live load without excessive distortion and not less than two and one-half times the design live load without failure.

      (2)   Recovery. After 24 hours under the total static load, upon removal of the load, the construction shall recover not less than one-half of the total deflection.

      (3)   Comparative Tests. When not available from existing authoritative test data, the building official may require comparative tests of standard traditional forms of construction assemblies of similar dimensions and sizes, to assist in determining the adequacy of the new construction.

   (d)   Concentrated Load Tests. Where design for concentrated loads is required in Section 13-52-130, floor constructions not capable of design shall be subjected to a concentrated load test when such loading exceeds in stress effect the prescribed uniformly distributed load.

(Prior code § 69-5.4; Amend Coun. J. 6-14-95, p. 2841)

13-120-130 Workmanship test.

   (a)   Whenever there is reasonable doubt as to the stability or structural safety of a completed building or structure, or part thereof, for the intended use, the Building Commissioner may require a load test of the building unit or portion of the structure.

   (b)   Unless otherwise provided for in this Code, the structure under consideration shall be subjected to a superimposed load equal to two times the design live load which shall be left in position for a period of 24 hours. If during the test, or upon removal of the test load, the structure shows evidences of failure, the Building Commissioner shall order such reinforcement or modifications deemed necessary to insure adequacy of the structure for the rated capacity; or in lieu thereof, the Building Commissioner may determine the safe load capacity to which the structure shall be limited.

   (c)   The structure shall be considered to have successfully passed the test if the total deflection does not exceed the theoretical deflection computed by accepted engineering formulae, or if the total deflection exceeds the theoretical value, the structure shall be considered safe for the design load if it recovers 75 percent of the maximum deflection within 24 hours after removal of the test load.
