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.
