1714.3 - In-situ load tests
In-situ load tests shall be conducted in accordance with Section 1714.3.1 or 1714.3.2 and shall be supervised by a registered design professional. The test shall simulate the applicable loading conditions specified in Chapter 16 as necessary to address the concerns regarding structural stability of the building, structure or portion thereof.
1714.3.1
Load test
procedure specified. Where a standard listed in Chapter 35 contains an
applicable load test procedure and acceptance criteria, the test procedure and
acceptance criteria in the standard shall apply. In the absence of specific
load factors or acceptance criteria, the load factors and acceptance criteria
in Section 1714.3.2 shall apply.
1714.3.2
Load test procedure not
specified. In the absence of applicable load test procedures contained
within a standard referenced by this code or acceptance criteria for a specific
material or method of construction, such existing structure shall be subjected
to a test procedure developed by a registered design
professional that simulates applicable loading and deformation
conditions. For components that are not a part of the seismic-load-resisting
system, the test load shall be equal to two times the unfactored design loads.
The test load shall be left in place for a period of 24 hours. The structure
shall be considered to have successfully met the test requirements where the
following criteria are satisfied:
1. Under the
design load, the deflection shall not exceed the limitations specified in
Section 1604.3.
2. Within 24 hours
after removal of the test load, the structure shall have recovered not less
than 75 percent of the maximum deflection.
3. During and immediately after the test, the
structure shall not show evidence of failure.
