Description

[0001] The present invention relates to a testing apparatus for evaluating structural performance of structures,

TECHNICAL FIELD The present invention relates to a structure performance test apparatus, and more particularly, to a structure performance test apparatus capable of performing a performance test on various types of test bodies.

In general, an earthquake is a phenomenon in which a sudden movement occurs in a part of a rock constituting the earth due to the energy accumulated in the earth, and a seismic wave is generated. Sudden crustal fluctuations are generated in the earth, Seismic waves propagate to the ground surface and apply an external force to the ground.

Because of such an earthquake, buildings and civil engineering facilities are designed considering earthquake, seismic or damping. Of course, buildings and civil engineering facilities continue to receive lateral forces such as tensile and compressive forces on structures such as pillars and walls, even if they are not earthquakes.

Therefore, buildings and civil engineering facilities are experimented with the strength of the structures against the lateral force before they are reflected in the design.

As an example of a conventional experimental apparatus for such an experiment, Korean Patent No. 10-1352787 is representative. 1, a lateral force cylinder (actuator) 600 for applying a lateral force to the wall 200, which is erected perpendicular to the bottom surface 100, is provided.

In such a conventional art, the actuator 600 tests the seismic performance of the test body 500 by applying a lateral force to the test body 500. However, this prior art has a problem in that it can not actually measure warpage, shear fracture strength, and adhesive fracture strength due to tensile force or compressive force, because the test is performed by applying an external force (lateral force) to the side of the horizontal test specimen 500.

Therefore, the applicant of the present invention has studied an experimental apparatus capable of measuring various deformation and strength by providing a lateral force in a vertical state of a test body such as a column or a wall. (Prior Art 1) was developed.

According to the prior art 1 of the present applicant, since the one end of the specimen having a length is installed in close contact with a part of the specimen, the specimen is installed in a state of being spaced apart from the ground surface and moved in the lateral direction by the lateral force provided on one side, And a moment generating prevention part for preventing a moment from being generated in the mover moving in the lateral direction by guiding the mover to allow the mover to move horizontally while moving the mover to transmit the load for measuring the earthquake- Wherein the moment generation preventing portion guides the mover at an upper portion of the mover, wherein the moment generation preventing portion includes at least one of a fixed body provided in a state of being perpendicular to the paper surface and at least one of both ends of the fixed body, An upper frame which is fixed and located on the upper portion of the mover, It is hinged to the side, and the other port is configured to be connected to a hinge connected to the mover.

At this time, a lateral force cylinder is installed on one side of the mover to provide lateral force and axial force to the mover, and an axial force supplier is installed on the upper side of the mover.

However, in the prior art 1 described above, in order to support the lateral force cylinder connected to the mover, the tip of the lateral force cylinder and the base end of the lateral force cylinder are connected to the wall of the mover There is a problem that movement and installation of the experimental apparatus are limited.

In addition, when a lateral force cylinder is installed on the wall, there is a problem that a reaction force acts on the wall due to the operation of the lateral force cylinder, so that the stress is continuously applied to the wall and is damaged. In addition, when the height of the test body is significantly lower than that of the mover, There is a problem that the setting operation is difficult for the experiment because a plurality of simplifications for the height adjustment need to be interposed.

In addition, since the type of the test object for testing the performance is limited, various experiments can not be performed, and thus the reliability of the test object performance is deteriorated.

[ This lateral force mover 225 may be formed in a flat portion in contact with the test body t, but may be deformed depending on the shape of the test body t in some cases. For example, when the test body t has a cylindrical shape, one side of the lateral force mover 225 that contacts the test body t may be formed to conform to the contour of the test body t.

3, the lateral force mover 225 and the axial force mover 214 may be separated from each other so as to be in contact with the test piece t independently. However, in some cases, The lateral force mover 225 may be fixed and formed integrally in a substantially "prep" form.
