Abstract
The invention belongs to the technical field of structural engineering, and particularly relates to a self-resetting buckling restriction support. The self-resetting buckling restriction support is composed of a core, a steel tube sleeve, binder-less materials, mortar, a pre-stressing tendon, rubber blocks, a steel plate and an anchorage device, wherein the core longitudinally penetrates through the steel tube sleeve, a yielding segment on the middle section of the core is inside the steel tube sleeve, non-yielding segments at two ends of the core extend out of the steel tube sleeve, the mortar fills spaces between the core and the steel tube sleeve, the surface of the core is provided with the binder-less materials, the rubber blocks are located at two ends of the steel tube sleeve, the steel plate is tightly attached to outer sides of the rubber blocks, the pre-stressing tendon passes through the mortar, the rubber blocks and the steel plate, and the steel plate and the core are welded into a whole after the components of the self-resetting buckling restriction support are anchored by stretching and drawing the pre-stressing tendon. According to the self-resetting buckling restriction support, the core which is easy to yield is repeatedly pulled and pressed under earthquake action, and therefore energy is consumed due to hysteresis of the core. After seismic oscillation finishes, the self-resetting buckling restriction support can return to an initial position, and enables a supporting member to almost have no residual deformation and keep working.
Description
Technical field
The invention belongs to technical field of structural engineering, be specifically related to a kind of from resetting buckling-restrained support.
Background technology
But the restore funcitons structure is a kind of novel Aseismic Structure System, is based on to produce under the seismic design guiding theory of performance.But be a kind of in the restore funcitons structural system from the resetting structure system, this structural system can be got back to initial position later in earthquake, and the permanent set of structure and member is very little, has guaranteed that then structure do not collapse in earthquake, and has continued to use.
Being supported in the structure lateral resisting system is one very important defence line.Common support pressurized is different with examining tensile behavior, easy unstability during pressurized; Tradition is buckling-restrained to be supported on when being subjected to very big pulling force, and permanent set is big.The present invention proposes a kind of effect that not only can provide support from the buckling-restrained support that resets, consume the earthquake ability in earthquake, after earthquake, the initial tensile stress of presstressed reinforcing steel can also allow core be returned to initial position, it is minimum that the permanent set of support is dropped to, and reduces the remaining displacement of structure.
Summary of the invention
The objective of the invention is to overcome the existing deficiency that supports and provide a kind of and have from resetting and the support of energy dissipation capacity, this support can be in earthquake earthquake energy, can after shake, be returned to initial position again.
To achieve these goals, the technical solution used in the present invention is:
A kind of from resetting buckling-restrained support, comprise core, steel pipe sleeve, non-cohesive material, mortar, presstressed reinforcing steel, block rubber, steel plate and ground tackle.
Described core, its interlude are the surrender sections, are made by the low-yield steel; The shape at two ends is identical, is non-surrender section, and the cross sectional area at two ends is greater than the cross sectional area of interlude.This core and is positioned at the center of steel pipe sleeve vertically in the steel pipe sleeve, and the surrender section of interlude is in the steel pipe sleeve inner, and the non-surrender section at two ends is stretched out outside the steel pipe sleeve;
Described mortar riddles between core and the steel pipe sleeve, one deck non-cohesive material is arranged as separation layer between mortar and the core.The Si Jiaochu of mortar has the presstressed reinforcing steel duct, and this duct is passed for presstressed reinforcing steel.
Described block rubber is positioned at the two ends of steel pipe sleeve, and there is square hole in the centre of block rubber, and this square hole passes for the end of core, and the Si Jiaochu of block rubber has circular hole, and these circular holes pass for presstressed reinforcing steels.
Described steel plate is close to the outside of block rubber, and square hole and circular hole correspondence position with on the block rubber have same square hole and circular hole above the steel plate, and these square holes and circular hole pass for end and the presstressed reinforcing steel of core respectively.
Described ground tackle is anchored on the steel plate.After the tension of prestressed tendon anchored, steel plate and core are welded into one.
Described presstressed reinforcing steel is not for there being bonding low relaxed prestress muscle.
The present invention passes through the easy core of surrendering tension and compression hysteretic energy repeatedly under geological process.After earthquake motion finished, the buckling-restrained support that resets certainly still can be returned to initial position, makes supporting member almost not have permanent set, can work on.The present invention can be widely used in the engineering structures, when geological process, has both realized the power consumption effect of core, can return to original state again after shake, changes simple and fast simultaneously.Simple structure of the present invention, easy construction is conducive to carry out and applies on a large scale.
