Description
Technical field
The present invention relates to a kind of shear wall structure, and in particular to a kind of post edge of a wing double X-type prestress steel framework-steel plate shearing
Wall construction.
Background technology
Steel plate shear wall structure is the one kind for developing and growing up on thin webbed girder theoretical research foundation with steel frame
Embedding steel plate is the new Lateral Resistant System of basic structural unit.Steel plate shear force wall has following good superior function：It is 1. initial
Lateral rigidity is big, and Hysteresis Behavior is stable, and energy dissipation capability is strong, and ductility is big, and it is good etc. excellent to resist deformability under cyclic load
Point.2. for steel frame-armored concrete core barrel structure, as Core Walls Structure is changed to steel plate wall construction, its rigidity can be significantly improved
And ductility, the matching with housing frame material, ductility, rigidity is realized, reaches the dual purpose set up defences.Simultaneously because itself and reinforcing bar mix
Coagulate native shear wall to compare from heavy and light, geological process is small, so as to be delivered to the vertical and horizontal loading on basis reduces, reduces basis
Cost.3. the setting of steel plate is embedded in steel plate wall can alleviate the Ductility Requirement in concrete frame joint area, reduce in severe earthquake action
The earthquake reaction of lower rigid joint, while joint structure can be simplified so that it is possibly realized using structures with semi-rigid joints.4. in steel plate wall
Embedding steel plate is relatively thin, and ratio of height to thickness can increase the effective usable floor area in house up to 250~500.5. steel plate wall structure construction is simple, build
Make that speed is fast, at home and abroad obtained wide application.
Reached full growth pulling force field studies have found that the force-mechanism of steel plate shear wall structure is interior fill plate, frame column will be held
Larger additional lateral load is carried on a shoulder pole, if Steel Frame Column insufficient rigidity, frame column has obvious " interior concave change under pull strap effect
Shape ".Excessive " Inward deflection " reduces stress in the middle part of steel plate wall, and close to the stress increase of styletable, finally in column end shape
Into plastic hinge, frame column deformation shows obvious " hourglass " shape, can cause its premature failure, it is impossible to give full play to steel plate and cut
The advantage of power wall construction.Steel frame-steel plate shear wall structure has a larger lateral resistance, but the H under larger load action
The steel column edge of a wing is smaller due to constraining, and local buckling can first occur, the inner side edge of a wing is the most serious.Post H profile steel premature degradation, loses
The effect of the strong anchoring frame of steel plate shear wall structure.The destruction of steel column causes overall structure can not undertake bigger load,
Limit it and popularization and application are obtained in engineering.
Connecting elements is set in the post edge of a wing for the design that solves the above problems is a kind of --- sway brace, it can be effectively increased
The globality on the edge of a wing, strengthen cooperation performance, effectively solve the above problems.But if sway brace uses horizontal positioned steel
Muscle spot welding there may be problem with the post edge of a wing：Lateral connection tie-rod point is welded in limited to the restriction range on the edge of a wing on the inside of the edge of a wing, weldering
Seam is more easy to crack, while larger residual stress and residual deformation will can be produced at spot welding, it may be caused to exit work in advance
Make.
