Abstract
The invention relates to a rectangular steel pipe concrete column and steel plate shear wall node structure and a construction method, belonging to the field of building structures. By adopting the structure, the problem that the wall of a steel pipe in a rectangular steel pipe concrete column is easy to damage by pulling buckling when connecting the rectangular steel pipe concrete column with a steel plate shear wall can be solved. The scheme is as follows: one end of a fishplate for connection extends into the rectangular steel pipe concrete column, and an anti-shear connecting part is welded at the end of the fishplate, thereby preventing the internal force of the steel plate shear wall from being directly acted on the wall of the rectangular steel pipe, effectively avoiding local buckling of the steel pipe and effectively transferring the force on the shear wall to the rectangular steel pipe concrete column. Simultaneously, the rectangular steel pipe concrete column is used as an effective embedding and fixing boundary, thereby enabling the steel plate shear wall to fully play the bearing capacity and the energy dissipation capacity, and enabling the two to realize better cooperative work.
Description
Technical field
The invention belongs to building structure field, refer more particularly to the method for attachment of steel plate shear force wall and rectangular steel-tube concrete column node.
Background technology
Concrete-filled rectangular steel tube is fill concrete and the member that forms in rectangular steel pipe, and it is mainly used in the frame column in the building.Concrete-filled rectangular steel tube has advantages such as bearing capacity height, ductility is good, anti-seismic performance is superior, compares with concrete filled steel tube, has also that the cross section bending rigidity is big, bending resistance good, joint structure is simple, be easy to advantages such as finishing.Along with the increase of depth of building, especially for highrise building, horizontal wind load or seismic load become the governing factor of structure design, so being chosen in of lateral resistant member seems particularly important in the highrise building.In recent years, steel plate shear force wall is with its stable energy dissipation capacity, and form of construction work is subjected to extensive concern efficiently.Steel plate shear force wall is especially for thin steel plate shear wall, and when its frame column with periphery all was connected with beam, peripheral frame had good anchorage effect to steel plate, can give full play to performance after the flexing of steel plate shear force wall.
Concrete-filled rectangular steel tube framework and steel plate shear force wall all have higher capacity, good ductility and energy dissipation capacity, and both can realize combination among the strong ones at common use, can effectively improve the lateral resisting ability of structural system.Yet there are no the record of the node connected mode of relevant rectangular steel-tube concrete column and steel plate shear force wall, steel plate shear force wall is when the interlayer sideways displacement angle is big, the steel plate tension forms pull strap on diagonal, if the steel pipe of steel plate and concrete-filled rectangular steel tube directly links to each other, steel plate in the steel pipe is prone to unstability outside the plane under tension, cause the early damage of steel core concrete column, the pull strap in the steel plate shear force wall can not fully be carried out simultaneously, and bearing capacity can not effectively be brought into play.
Summary of the invention
The present invention seeks to propose effective method of attachment of a kind of rectangular steel-tube concrete column and steel plate shear force wall, can avoid the steel pipe walls in the rectangular steel-tube concrete column to be drawn in the wrong destruction, by the effective anchor plate shear wall of rectangular steel-tube concrete column, make the pull strap of steel plate shear force wall fully carry out, give full play to its bearing capacity and ductility.
The structure that realizes technical solution of the present invention is at concrete-filled rectangular steel tube framework and steel plate shear force wall node section splice bar to be set, the splice bar that will link to each other with rectangular steel-tube concrete column extends to steel core concrete column inside, on the splice bar that extends to steel core concrete column inside, weld shear connector, the splice bar of steel core concrete column outside is connected with steel plate shear force wall, the active force of steel plate shear force wall is directly passed to rectangular steel-tube concrete column by the shear connector on the splice bar, avoids steel pipe walls directly to bear the active force that steel plate shear force wall produces.
Job practices of the present invention is, when the steel pipe welding of splice bar and rectangular steel-tube concrete column, the welding position of steel pipe at splice bar disconnected, on splice bar, weld shear connector again, the splice bar that then will have shear connector inserts in the empty steel pipe of the rectangle that has perps, connects steel pipe and splice bar with two-sided side weld then; At the construction field (site), after being welded with the empty steel pipe installing and locating of splice bar, steel plate shear force wall is adopted in welded or bolted way and is linked to each other with splice bar, then concreting in rectangular steel pipe, after treating hardening of concrete, realize that rectangular steel-tube concrete column is connected with the effective of steel plate shear force wall.
This joint connecting method is not only applicable to the node of steel plate shear force wall and rectangular steel-tube concrete column, is applicable to the node of steel plate concrete compound shear wall and rectangular steel-tube concrete column yet.
This node connected mode has the following advantages:
1, passes through splice bar is inserted in the rectangular steel pipe, and on splice bar, weld shear connector, effectively avoided the internal force of steel plate shear force wall to act directly on the steel pipe walls, avoided the part of steel pipe to draw in the wrong destruction; Effectively steel plate internal force is directly passed to rectangular steel-tube concrete column;
2, steel core concrete column can fully carry out the pull strap on the steel plate shear force wall as effective anchoring border of steel plate shear force wall, has given full play to performance after the flexing of steel plate shear force wall, has improved bearing capacity and ductility.
