Description
Technical field
The present invention relates to a kind of prefabricated assembled anti-buckling steel plate shear force wall applied in building engineering structure field and
Its construction method, the invention highlight lines that are particularly suitable for use in are set up defences the assembled architecture of earthquake territory.
Background technology
Steel plate shear force wall is a kind of new and effective lateral resistant member, compared with traditional reinforced concrete shear wall, tool
There is the features such as high capacity, deadweight is small, ductility is good, anti-seismic performance is superior, the highlight lines that are particularly suitable for use in are provided fortification against earthquakes area.
At present, anti-buckling thin steel plate shear wall is widely used, but also faces some problems and need to further solve:First, steel
Plate shear wall is divided into four sides or both sides junction steel plate shear wall according to the difference with edge member connection;Four side junction steel plates
Shear wall superior performance, but be unfavorable for elevator, door and window and the arrangement in passageway, while frame column can also be produced larger attached
Add internal force;And though both sides connect the arrangement that anti-buckling steel plate shear force wall is easy to the holes such as door and window, passageway, steel plate is embedded due to two
Side does not have the constraint of edge member, causes the performance of embedded steel plate can not give full play to, four corner stress concentrations of steel plate,
Easily occur steel plate tear ahead of time, it is low that bearing capacity and anti-seismic performance compared with four sides connects anti-buckling steel plate shear force wall, therefore both sides company
Connecing the performance of steel plate shear force wall urgently improves.Secondly, the connection of steel plate shear force wall and edge member passes through fish platee mostly at present
Welding is realized so that site operation needs more on-the-spot welding, and weldquality is whard to control and influences efficiency of construction, hinders
Its application in assembled architecture;Also, the residual stress of weld seam peripheral region can cause the reduction of steel plate shear force wall performance;Together
When, existing investigation and study shows that easily under geological process brittle break occurs for solder design, causes to build heavy damage, no
Beneficial to being repaired after shake.Therefore, steel plate shear force wall as described above is faced with terms of connecting structure and construction technology urgently enters one
The problem of step improves.
