For the shock insulation building with larger height and width, the rubber shock insulation support at the corner of the building is easy to generate tension phenomenon under the action of strong shock. When the rubber shock insulation support is subjected to stretching action, the internal rubber of the rubber shock insulation support can shrink in the horizontal annular direction under the action of vertical tension, negative pressure is easily formed in the rubber, adverse phenomena such as empty holes and tensile stress concentration can be generated in the rubber, and when the rubber shock insulation support is subjected to larger tension deformation, the vertical compression rigidity of the rubber shock insulation support can be greatly reduced when the rubber shock insulation support is compressed again, and the performances of the rubber shock insulation support and the safety of a shock insulation structure can be greatly influenced.
The friction pendulum vibration isolation support is a vertical tensile discontinuous component, when the corner of a vibration isolation building is in tension under the action of strong vibration, the components of the friction pendulum vibration isolation support can be separated, the vibration isolation support temporarily loses the vibration isolation energy consumption capacity of the vibration isolation support, when the building falls back, serious impact can be generated, the safety of the friction pendulum vibration isolation support and a vibration isolation structure is affected, and when the lifting height of the building is large, overturning can be even generated.
In bridge structures, in order to transfer various loads of an upper structure to a pier and adapt to deflection (including displacement and rotation angle) generated by various factors such as load change, temperature change, shrinkage and expansion of concrete, earthquake wind vibration and the like, bridge supports are required to be installed between a bridge and a bridge pier, and in order to make longitudinal and transverse displacement and rotation angle generated by deformation of a beam body not limited as much as possible, tensile bearing capacity of a common bridge support structure is often deficient, which causes hidden trouble to bridge safety and even multiple bridge overturning accidents in recent years.

The tensile support can meet various tensile load bearing requirements by adjusting the size of the members or using materials of different yield strengths, and can also improve the tensile load bearing capability by increasing the number of hinge assemblies 3. One upper track 1 as shown in fig. 17a, 17b cooperates with two hinge assemblies 3. Of course, a greater number of hinge assemblies 3 may be fitted as desired.
The working principle of the combination of the tensile support 6 and the shock insulation support 7 in the present embodiment is specifically described below:
the upper slide rail 1 and the lower slide rail 2 are fixed on the upper embedded part 50 and the lower embedded part 51 through welding or bolting, the embedded anchor bars can be directly welded on the upper embedded part 50 and the lower embedded part 51, and can also be fixed through bolting and sleeve connection, the upper embedded part 50 is poured into the upper support pier 52, and the lower embedded part 51 is poured into the lower support pier 53, as shown in fig. 16. The shock-insulating supports 7 and the tension supports 6 are arranged in the manner of fig. 18.
When an earthquake occurs, the tension support 6 can slide freely along with the sliding of the shock insulation support 7 in the horizontal direction, and the shock insulation support 7 is not prevented from functioning. In the vertical direction, when the shock insulation support 7 generates smaller vertical displacement, the tensile support 6 changes along with the change of the shock insulation support, when the upward displacement of the shock insulation support 7 reaches a certain value, the tensile support 6 reaches limit along with the contact of two hinging seats on the lower sliding rail 2, and at the moment, the tensile support 6 is integrally pulled to provide vertical bearing force for the shock insulation support 7.
The cooperative working process of the shock insulation layer comprises the following steps: when the shock insulation support 7 works normally, the tensile support 6 does not influence the movement of the shock insulation support; when the shock insulation support 7 horizontally reciprocates, the height of the support changes, and the tensile support 6 changes along with the height change of the shock insulation support 7; when the shock insulation support 7 receives larger tensile stress or generates larger lift-off displacement, the tensile support 6 acts to increase the tensile bearing capacity of the shock insulation layer; the tension support 6 can also rotate with it to accommodate the deformation when the structure makes a small angle of rotation.
As shown in fig. 19: the working principle of the combination of the tensile support 6 and the bridge support 8 applied to the bridge is similar to that of the combination of the tensile support 6 and the shock insulation support 7, and will not be described in detail herein.
