Apply example.Identical appended drawing reference denotes same or similar part or part in attached drawing.It should be appreciated by those skilled in the art that
The drawings are not necessarily drawn to scale.In attached drawing：
Fig. 1 is the schematic diagram of the hollow square pile beam test device of an embodiment of the present invention.
Specific embodiment
As shown in Figure 1, present embodiment discloses a kind of hollow square pile beam test device, the experimental rig includes：Point
Not She Yu hollow square pile both ends bottom surface, the first secondary station 1 and the second secondary station 2 for placing the hollow square pile 100, place
Third secondary station 3 on the hollow square pile 100, first secondary station 1 include the first buttress 11, the first fixed-hinged support
12, second secondary station 2 includes the second buttress 21, the first rolling hinged support 22, and the third secondary station 3 includes distribution beam
31 and second fixed-hinged support 32 at 31 both ends of distribution beam, the second rolling hinged support 33, the distribution are separated from respectively
Beam 31 is equipped with the weight 34 with load.
First rolling hinged support 22, the second rolling hinged support 33 are spherical slip support abutments:Vertical direction is immovable, can be with
Rotation, can move in the horizontal direction.
First fixed-hinged support 12, the second fixed-hinged support 32:It can rotate, level, vertical direction are immovable.
The working principle of the experimental rig is：Loading procedure should include following the description：
The first step：It is loaded onto the 80% of ring cross-section by 20% differential of ring cross-section, every level-one load duration is not
Less than 3min；Then by 10% differential continue to be loaded onto ring cross-section 100% of ring cross-section.The duration of every level-one load
No less than 3min has seen whether crack appearance, measures and records fracture width.
Second step：If not occurring crack in the 100% of ring cross-section, differential continue to load by the 5% of ring cross-section
Occur to crack, the duration of every level-one load is no less than 3min, measures and record fracture width.
Third step：Differential continue to be loaded onto until there is one of situation set forth below by the 5% of ultimate bending moment.Every level-one
The duration of load is no less than 3min, observes and records every reading.
