Description
(1) technical field:
The present invention relates to a kind of building structural element, relate in particular to a kind of building structure supporting member that is used in the earthquake resistant engineering field.
(2) background technology:
In recent years, develop rapidly along with socioeconomic, the quickening day by day of urbanization process, the building of various various kinds moulding complexity, function uniqueness continues to bring out.Though the development of the design-build technology of the development of modern project technology, particularly high building structure is achieved these building schemes; But big shake earthquake in recent years also shows, the agent structure in seismic process of building although it is so is not subjected to tangible destruction, but because agent structure is gentle partially, causes malformation excessive, thereby cause the heavy damage of non-structural element and related service facility, lose huge; And, cause shake back reparation difficulty or cost too high because such structure often all can produce nonlinear deformation, the requirement of discontented foot channel Ji.
In order to reduce the distortion of this class formation under the geological process, people tend to set up some steel supporting components in structure, to improve the integral rigidity of structure.But traditional steel supporting component can produce the phenomenon of flexing when the severe earthquake action pressurized, thus often the supporting member section is strengthened adhering to specification, but still be difficult to guarantee under macroseism, do not take place the flexing unstability.In view of this, the axle power member of flexing unstability can not take place when some researchers in Japan, the U.S. and China Taiwan have developed a kind of pressurized recently, be referred to as to frustrate in the wrong restraining in China Taiwan and support (BucklingRestrained Braces, be called for short BRB), then be referred to as not have bonding support (Unbonded Braces is called for short UBB) in the U.S. and Japan.Consider that this member has very strong energy dissipation capacity behind material yield, in actual engineering, it can be supported as power consumption and use.At present, this member has obtained extensive use in Japan, the U.S. and China Taiwan; At home, still be in the starting stage of research, engineering is used less.
It is that a kind of all can reaching when tension and pressurized surrendered and the axle power member of flexing unstability is not taken place that buckling-restrained power consumption is supported, and compares with traditional center support to have more stable mechanical property.Through suitably design, the framework that contains buckling-restrained power consumption support not only can increase integral rigidity, improve structure ductility, and because characteristic that can flexing during its pressurized can be given full play to the hysteresis energy dissipating ability of steel, therefore, this member has possessed the function of center support and displacement type damper simultaneously, has important use in the earthquake resistant engineering field and is worth.
Generally speaking, buckling-restrained power consumption is supported by three parts and is formed, i.e. core steel support, overcoat constraint steel pipe and sliding mechanism.The core steel supports, and is called the main stress unit again, is force-summing element main in the member; Overcoat constraint steel pipe is called the lateral support unit again, is responsible for providing tied mechanism, to prevent the support of core steel integral body or cripling takes place when being subjected to axial compression.In addition, for avoid the core steel support because of be subjected to after the compression swelling and between overcoat constraint steel pipe generation bond or frictional force causes rolling up of axial pressure, must between support of core steel and overcoat constraint steel pipe, a kind of sliding mechanism be set, at present, this sliding mechanism is mainly provided by the unsticking knot material of filling between support of core steel and the overcoat constraint steel pipe.
Fig. 1 is the structure phantom drawing that a kind of common buckling-restrained power consumption is supported.The packing material 4 that the core steel support 1 that buckling-restrained power consumption support shown in the figure is made of steel plate, overcoat constraint steel pipe 2, unsticking knot material 3, concrete or mortar constitute is formed.Wherein, the core steel supports and directly bears a power load, is made up of the steel plate of certain strength; 4 pairs of core steel of overcoat constraint steel pipe 2 and packing material support and form constraint, and the core steel supports the flexing unstability takes place when preventing that axial compression from acquiring a certain degree; Unsticking knot material is made of special chemical material, can cut off the core steel and support and packing material, can free dilatation when making the core steel be supported on pressurized.Above-mentioned existing buckling-restrained power consumption is supported and is had three major defects:
1, the core steel supports and need be made of the certain strength steel plate, and the material range of choice is restricted, and the difficulty of processing and manufacturing is big, and the cost height is unfavorable for promoting the use of in engineering.
2, unsticking knot material 3, what should guarantee that the core steel supports axially is free to slide, it is unfettered to make the core steel support lateral expansion again, also wants strict its thickness of control simultaneously, can not be too thick again can not be too thin, therefore, must need to adopt special chemical material.Like this, just increase the manufacture difficulty and the cost of member, the transition that has caused buckling-restrained power consumption to support unsticking knot material simultaneously relies on.
3, adopt concrete or mortar as packing material, the perfusion operation is difficulty relatively.In the actual engineering, the length that buckling-restrained power consumption is supported is bigger, and is general all more than 4 meters.At this moment, should guarantee that concrete or mortar injection are closely knit, guarantee that again the relative position that overcoat constraint steel pipe and core steel support can not be offset, be the comparison difficulty.
(3) utility model content
In order to overcome the above-mentioned deficiency that existing buckling-restrained power consumption is supported, solve the material range of choice limited, make and install problem loaded down with trivial details and that cost is high, the utility model provides the buckling-restrained power consumption of a kind of crack with seam and anti-skidding projection to support.
