Contrast test:Low-cycle Test
Experiment process divides three phases:
1. preloading phase before experiment:Before experiment, first pre-add cyclic reverse loading is secondary, and vertical load adds to pre- constant load
50%, horizontal pre-loaded value calculates the 20% of cracking load for test specimen, and main purpose is that elimination test specimen inside is that may be present not
Uniformity.
2. load controls the stage:Vertical load is applied according to the axial compression ratio of design first, and is kept not during experiment
Become.Then reciprocal horizontal loading is applied, every grade cycles 1 time, and every grade of load is 10kN.According on the outside of test specimen bottom end edge
Reinforcing bar reaches yield strain and judges test specimen surrender, and records corresponding yield displacement.
3. the Bit andits control stage:Bit andits control is changed to after test specimen surrender, by the multiple CYCLIC LOADING of yield displacement, per level-one
Displacement cycle 3 times, when test specimen can not bearing load or horizontal loading drop to 85% or so of peak load again when, experiment knot
Beam.
Table 1:Comparative test result:
The ultimate load of embodiment 1 is respectively increased compared with comparative example 1 and comparative example 2 it can be seen from the data of table one
57.7% and 29.5%, 45.7% and 26.4% has then been respectively increased in extreme displacement.Fractue spacing scope after the experiment of embodiment 1
More extensively and evenly, wherein maximum crack width and remaining fracture width is substantially reduced.And the residual deformation of embodiment 1 is then
9mm has been narrowed down to, has reduced 51.4% and 44.1% respectively on year-on-year basis, has illustrated the oblique concealed bracings for adding nitinol alloy wire composition
Afterwards, the runback bit function of wall is good.Per under level-one load action, the hysteretic loop that load-displacement curve is surrounded typically represents examination
The size of part energy consumption, this experiment wall hysteretic loop is fuller, area bigger, illustrates the concealed bracings for adding nitinol alloy wire composition
The energy consumption of back wall is more preferable.
The foregoing is merely the exemplary embodiments of the present invention, do not limit the present invention with this, all spirit in the present invention and
All any modification, equivalent and improvement made within principle etc., should all be included in the protection scope of the present invention.
