(a) Roof Load Tests. The following is an acceptable test procedure for roof trusses that are supported at the ends and support design loads. Where roof trusses act as support for other members, act as cantilevers, or support concentrated loads, they shall be tested accordingly.
(b) General. Trusses may be tested in pairs or singly in a suitable test facility. When tested singly, simulated lateral support of the test assembly may be provided, but in no case shall this lateral support exceed that which is specified for the completed commercial coach. When tested in pairs, the trusses shall be spaced at the design spacing and shall be mounted on solid support accurately positioned to give the required clear span distance (L) as specified in the design. The top and bottom chords shall be braced and covered with the material with connections or method of attachment as specified by the completed commercial coach.
(1) As an alternate test procedure, the top chord may be sheathed with 1/4 inch by 12 inch plywood strips. The plywood strips shall be at least long enough to cover the top chords of the trusses at the designated design truss spacing. Adjacent plywood strips must be separated by at least 1/8 inch. The plywood strip shall be nailed with 4d nails or equivalent staples not closer than 8 inches on center along the top chord of one truss only. The bottom chords of the adjacent trusses may be either: (A) unbraced, (B) laterally braced together (not cross braced) with 1 " x 2 " stripping not closer than 24 inches on center nailed with only one 6d nail at each truss, or (C) covered with the material with connections or methods of attachment as specified for the completed commercial coach.
(2) Truss deflections will be measured relative to a taut wire running over the support and weighted at the end to insure constant tension or other approved methods. Deflections will be measured at the two quarter points and at midspan. Loading shall be applied to the top chord through a suitable hydraulic, pneumatic, or mechanical system, masonry units, or weights to simulate design loads. Load units for uniformly distributed loads shall be separated so that arch action does not occur, and shall be spaced not greater than 12 inches on center so as to simulate uniform loading.
(c) Nondestructive Test Procedure.
(1) Dead Load Plus Live Load.
(A) Noting Figure A, measure and record initial elevation of the truss in test position at no load.
(B) Apply load units to the top chord of the truss equal to the full dead load of roof and ceiling. Measure and record deflections.
(C) Maintaining the dead load, add live load in approximately 1/4 design live load increments. Measure the deflections after each loading increment. Apply incremental loads at a uniform rate such that approximately one-half hour is required to establish the total design load condition. Measure and record the deflections five minutes after loads have been applied. The maximum deflection due to design dead load plus live load (deflection measured in Step (C) minus Step (B) shall not exceed L/180, where L is a clear span measured in the same units.
(D) Continue to load truss to dead load plus 1.75 times the design live load. Maintain this loading for 12 hours and inspect truss for failure.
(E) Remove the total superimposed live load. Trusses not recovering to at least L/180 position within 12 hours shall be considered as failing.
(2) Uplift Loads. This test shall only be required for truss designs which may be critical under uplift load conditions.
(A) Measure and record initial elevation of the truss in an inverted test position at no load. Bottom chord of the truss shall be mounted in the horizontal position.
(B) Apply the uplift load as stated in 4360.6 to the bottom of the chord of the truss. Measure and record the deflections 5 minutes after the load has been applied.
(C) Continue to load the truss to 1.75 times the design uplift load. Maintain this load for 3 hours and inspect the truss for failure.
(D) Remove applied loads and within three hours, the truss must recover to at least L/240 position, where L is a clear span measured in the same units.
(d) Destructive Test Procedure.
(1) Destructive tests shall be performed on three trusses to generally evaluate the truss design.
(2) Noting Figure A-1, apply the load units to top chord of the truss assembly equal to full dead load of roof and ceiling. Measure and record deflections. Then apply load and record deflections in 1/4 design live load increments at 10-minute intervals until 1.25 times design live load plus dead load has been reached.
(3) Additional loading shall then be applied continuously until failure occurs or a load equal to dead load plus 1.5 to the factor of safety times the design live load is reached.
(4) Assembly failure shall be considered as design live load deflections greater than L/180 rupture, fracture, or excessive yielding.
(5) The assembly shall be capable of sustaining the dead load plus the applicable factor of safety times the design live load (the applicable factor of safety for wood trusses shall be taken as 2.50).
(e) Trusses qualifying under the nondestructive test procedure (Tests C-1) and C-2) shall be subject to a continuing qualification testing program acceptable to the department. Trusses qualifying under the nondestructive and destructive test procedures (Tests C-1 and C-2, and D) shall be subject to retesting when required by the department.
