Description
Technical field
The present invention is mainly concerned with the steel structure member field that is used for building structure, refers in particular to a kind of H Steel section member that can be used for the lateral restrain in the house architectural structure design and construction of antidetonation area.
Background technology
Steel work has the intensity height, from heavy and light, series of advantages such as anti-seismic performance is good, speed of application is fast, ground cost saving, area occupied is little, industrialization degree is high, good looking appearance, compare with concrete structure, adopting steel work environmental protection and also can utilizing once more more, also is the structure that is easy to industrialization.Developed countries such as the U.S., Japan, Germany extensively adopt steel work in engineering construction, steel building will account for more than 40% of whole building, and the shared proportion of steel building of China is less than 5% at present, and this is with China's steel are underproduce relevant in the past.China's output of steel promotes significantly in recent years, and supply exceed demand then become." Chinese architecture technical policy " announcement (1996-2010) is a strong promotion to the development of steel work, has started the new period that steel work is used under construction, makes construction steel structure obtain developing rapidly." national construction steel structure industry the Tenth Five-Year Plan (2001-2005) and development planning outline (draft) in 2015 " points out that the developing goal of construction steel structure is to strive for reaching annual construction steel structure to account for 3% of national steel output with steel during "the 10th five-years"; The developing goal of construction steel structure in 2015 is that the steel using amount of striving for annual construction steel structure reaches 6% of steel total output.Can predict, steel work will more and more be applied in the construction work from now on.
H shaped steel is the section bar that every performance that a kind of cross section forms through optimization all is better than common i iron.H shaped steel can be divided into according to the manufacturing process difference: hot rolled H-shaped and welded H section steel.H shaped steel can be used as the main material of using of all kinds of steel buildings.According to statistics, substantially all be to adopt H shaped steel to form the structure stress system in 13 the highest high-rise steel structure of the world, its H shaped steel steel using amount accounts for 40%～80% of total steel using amount.The nineties in last century, the horse steel utilized home equipment that 650 milling train transformations have been built up article one H type steel production line.Later on roll in Laigang, Anshan one, introduction of foreign technology such as Jiangyin Xing Cheng and equipment built up hot rolled H-shaped production line in succession.China H shaped steel production capacity in 2005 is nearly 4,000,000 tons according to estimates, and in Tianjin, ground such as Beijing, Shandong, Hebei, Anhui released a collection of steel house demonstration project.Why H shaped steel so extensively is because he has the following advantages if being used: it is wide that (1) and i iron are compared the edge of a wing, and lateral rigidity is big; Two surfaces, the edge of a wing are parallel to each other, and joint construction is convenient; (2) with the concrete structure structure compared from heavy and light, speed of application is fast.For rolling H shaped steel, owing to there is not weld seam, residual stress is little, ductility good in addition.
Nineteen ninety-five occurs in the violent earthquake of Japanese Hyogoken-Nanbu, and the typical case that steel work takes place destroys and mainly contains cripling, brittle fracture and low-cycle fatigue failure.Why the steel member produces crippling near the moment of flexure maximum cross-section, mainly be owing to have the limit value of the plate flakiness ratio of material impact can not satisfy the plastic strain under the cyclic loading effect and the requirement of consuming energy to the steel member in the design, particularly under the bigger situation of axial load, situation is more obvious.
Summary of the invention
The technical problem to be solved in the present invention just is: at the technical problem of prior art existence, the invention provides a kind of anti-seismic performance that can effectively strengthen steel work, improve its ductility, and cost is lower, the H Steel section member of the lateral restrain of easy construction, thereby solved the local stable problem that the H Steel section member is occurred under geological process, improved its stability.
For solving the problems of the technologies described above, the solution that the present invention proposes is: a kind of H Steel section member of lateral restrain, this H Steel section member is girder steel or steel column, it is characterized in that: be provided with horizontal restrain and be provided with flexible dottle pin between the end of horizontal restrain and girder steel or steel column or bottom near end or bottom place on described girder steel or the steel column, this horizontal restrain comprises the outsourcing thing that is wrapped in H Steel section member periphery and is located at the filler in the cavity between the H Steel section member edge of a wing and the web; Be provided with first gap between the outline of described outsourcing thing and H Steel section member, be provided with second gap between described filler and the H Steel section member surface.
Described outsourcing thing is fibre reinforced plastics cloth or steel loop or steel plate or steel concrete or the wire mesh mortar outer envelope that is wrapped in H Steel section member outline.
Described filler is a concrete.
Be filled with flexible material in second gap between first gap between described outsourcing thing and the H Steel section member outline and filler and the H Steel section member surface.
Compared with prior art, advantage of the present invention just is:
1, the H Steel section member of lateral restrain of the present invention, this steel member is mainly girder steel or steel column, behind close end on girder steel or the steel column or place, bottom lateral restrain, can limit the issuable crippling under earthquake or other effects of H Steel section member effectively, but it does not change the stress performance of H Steel section member at elastic stage;
2, the H Steel section member of lateral restrain of the present invention, this horizontal restrain can prevent or postpone development and the low-cycle fatigue failure of H Steel section member in the issuable cripling of areas of plasticity hinge effectively, slow down the rapid decline of steel member supporting capacity after the bearing capacity that reaches capacity, thereby improve the ductility of H Steel section member, improve the anti-seismic performance of structure;
3, the H Steel section member of lateral restrain of the present invention, only to the end or the bottom lateral restrain of girder steel or steel column, promptly only the position that plastic hinge may occur is applied horizontal restrain, like this, can not change the design of conventional steel frame structure system, construction, and horizontal restrain of the present invention is simple in structure, construction technology is easy, can be generalized to easily in many existing antidetonations district steel framed structure;
4, the H Steel section member of lateral restrain of the present invention also can be transformed existing steel building simultaneously, only need end or bottom lateral restrain, thereby finish reinforcing, gentrify work existing steel building to H Steel section member in the existing steel building.
