Description
Technical field
The invention belongs to civil engineering structure experimental technique field, especially relate to a kind of new spatial for asymmestry section bias test and load bearing.
Background technology
In the bending test of frame column or the pseudo-static experimental of node, usually need to apply vertical and horizontal loading at capital, to consider the impact on pillar load-carrying properties or Seismic Behavior of axial compression ratio or P-Δ effect simultaneously.For cross-section centroid and the post cutting heart coincidence, existing pin hinge device can meet loading requirement.When pillar is the odd-shaped cross section such as L shape or grooved, its centre of form and cut the heart and often do not overlap, and the vertical and horizontal actuator of testing machine can only work in a face usually, when the current frame column bending test for this type of cross section or node pseudo-static experimental, usually horizontal loading and vertical load are all put on the centre of form in cross section, make pillar create additional torque, be not inconsistent with actual forced status, and add the difficulty of analysis.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and provide a kind of space for asymmestry section bias test load bearing.
Object of the present invention can be achieved through the following technical solutions: a kind of space for asymmestry section bias test loads bearing, comprise pin hinge component, horizontal balance device and vertical action device, described pin hinge component is made up of the otic placode a and otic placode b that is rotatably connected, wherein otic placode a is provided with upper plate and side plate, vertical action device is positioned on upper plate, horizontal balance device abuts side plate by waling stripe, otic placode b connects test specimen, horizontal balance device and vertical action device apply vertical load and horizontal load by pin hinge component to test specimen, it is characterized in that, also comprise conversion equipment and ball pivot, ball pivot is placed on the upper plate of described otic placode a, conversion equipment is placed on ball pivot, vertical action device is placed on conversion equipment, by conversion equipment and ball pivot, the center of vertical action device is overlapped with the centre of form of otic placode a, the centre of form of otic placode a overlaps with the centre of form of test specimen simultaneously, thus make vertical load all the time along the centre of form effect of test specimen.
Described otic placode a and otic placode b passes through pinned connection.
Described ball pivot center overlaps with the upper plate centre of form of otic placode a.
The centre of form of described plate b is alignd with the heart of cutting of the center of horizontal actuator and test specimen.
Principle of work: overlapped with the centre of form of the upper plate of otic placode a by the ball pivot center of converter device by vertical actuator, the centre of form of upper plate overlaps with the centre of form of test specimen simultaneously, thus ensures that vertical load is done all the time along the centre of form effect of test specimen; Capital horizontal loading acts on test specimen top by otic placode b, the centre of form of otic placode b is alignd with the center of horizontal actuator and the heart of cutting of test specimen, ensures that horizontal loading cuts heart effect along test specimen, thus avoids test specimen to bear moment of torsion.
Compared with prior art, the present invention by conversion equipment by vertical uniform load q in cross-section centroid, horizontal loads cuts the heart in cross section, simplifies the stress of pillar, makes it to be consistent with actual loaded state, also make its stress closer to Practical Project situation.
Accompanying drawing explanation
Fig. 1 is the structural representation of apparatus of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As described in Figure 1, a kind of space for asymmestry section bias test loads bearing, comprise pin hinge component 1, conversion equipment 2, ball pivot 3, horizontal balance device 4 and vertical action device 5, described pin hinge component 1 is made up of the otic placode a11 and otic placode b12 that is rotatably connected, otic placode a11 is connected by bearing pin 13 with otic placode b12, wherein otic placode a11 is provided with upper plate 111 and side plate 112, ball pivot 3 is placed on the upper plate 111 of described otic placode a11, conversion equipment 2 is placed on ball pivot 3, vertical action device 4 is placed on conversion equipment 2, ball pivot 3 center overlaps with upper plate 111 centre of form of otic placode a11, by conversion equipment 2 and ball pivot 3, the center of vertical action device 5 is overlapped with the centre of form of otic placode a11, the centre of form of otic placode a11 overlaps with the centre of form of test specimen 6 simultaneously, thus make vertical load all the time along the centre of form effect of test specimen.
Horizontal balance device 4 abuts side plate 112 by waling stripe 7, and otic placode b12 connects test specimen 6, and the centre of form of plate b12 is alignd with the center of horizontal actuator 4 and the heart of cutting of test specimen 6, ensures that horizontal loading cuts heart effect along test specimen, thus avoids test specimen to bear moment of torsion.
Ball pivot load active line 31 overlaps with test specimen centroidal line 61, vertical action device load active line 51 and ball pivot load active line 31 moment of flexure produced that do not overlap is born by vertical action device 5 and conversion equipment 2, because being connected by ball pivot 3 between conversion equipment 2 with pin hinge component 1, above-mentioned moment of flexure can not be delivered on test specimen, additional bending moment can not be produced to test specimen, only by its axle masterpiece for test specimen, simultaneously, the otic placode b12 be connected with horizontal balance device 4 cuts the heart with test specimen 6 and overlaps, thus achieves vertical load effect and test specimen centre of form horizontal load acts on the target that the heart cut by test specimen.
