Description
Technical field
The present invention relates to the steel plate shear force wall that a kind of novel tensile force of belt supports, belong to Structural EngineeringTechnical field.
Technical background
At present, adopt in the world steel plate shear force wall to have two as the building of main lateral resistant memberBuilding more than ten, is mainly distributed in the Areas of High Earthquake Intensity district such as North America and Japan. Since Japan in 1970Since iron company is applied in building by steel plate shear force wall, the development of steel plate shear force wall is existingMore than 40 year. Steel plate shear wall structure system is made up of embedded steel plate and edge member, edge structurePart comprises edge girder and edge posts. Embedded steel plate conventionally connects and composes lateral resisting with edge member and tiesStructure system, this structural system can be considered the cantilever beam fixing on the ground.
According to the thickness of embedded steel plate, steel plate shear force wall can be divided into steel plate shear wall and sheet metalShear wall; According to whether ribbing of surface of steel plate, steel plate shear force wall can be divided into stiffening rib steel plate shearingWall and non-stiffening rib steel plate shearing force wall; Whether crack according to surface of steel plate, steel plate shear force wall can divideFor slotted steel plate shear wall and slotted steel plate shear wall not; Whether arrange coagulation according to steel plate sideSoil plate, steel plate shear force wall can be divided into steel plate-concrete combined shear wall and general steel plate shear wall.Although thin steel plate shear wall has good economic benefit, its easier flexing. Other forms ofSteel plate shear force wall is target mainly with the deformity out of plane that stops steel plate greatly, allows steel plate protect as much as possibleHold and planar work to consume more energy.
In China's " Technical Specification for Steel Structure of Tall Buildings " JGJ99-98, annex four specifies,For preventing steel plate shear force wall generation shear buckling, should be using the shear buckling bearing capacity of steel plate as itUltimate bearing capacity, or make by steel plate is put more energy into, before its surrender, flexing does not occur. In fact,Above two kinds of modes are all partial to conservative and cost is higher, be unfavorable for steel plate shear force wall development andApplication. Along with going deep into of both at home and abroad steel plate shear force wall being studied, property after the flexing of steel plate shear force wallCan obtain paying close attention to widely, steel plate shear force wall still has higher bearing capacity, good after flexingGood ductility and stable energy dissipation capacity. Make full use of the Post-Bucking Strength of steel plate shear force wall notOnly can make structure obtain good anti-seismic performance, and can significantly reduce steel using amount, reduceCost, increases economic efficiency.
Summary of the invention
The present invention proposes the steel plate shear force wall that a kind of novel tensile force of belt supports, its object existsIn, overcome thin steel plate shear wall and can not give full play to the strength and ductility of steel because of too early flexingShortcoming, improved flat lateral stability and the ultimate bearing capacity of steel plate shear force wall, give full play toThe advantage of steel.
Do not establish the thin steel plate shear wall that pulling force supports, when load is during along a directive effect, embeddedSteel plate generation flexing also forms pull strap, is accompanied by larger face and is out of shape outward; When external load reverseDo the used time, pull strap originally, by reverse pressurized, no longer provides rigidity; Meanwhile, original being subject toNip territory will be transited into pulling force zone, but become owing to once there is larger lateral deflection under higher level's loadShape, is out of shape therefore have the process that is stretched to " open and flat ", until the formation of reversal interlocking relay band. At thisIn one process, steel plate cannot bearing load, and structure only depends on beam column to bear external load, like this anchoringPulling force field on framework can produce larger additional bending moment to side column, has increased the stable of pillarBurden. So the setting that pulling force supports, has limited on the one hand larger after embedded steel plate flexingDeformity out of plane, provides sidewise restraint; Two on the one hand, when load reversal does the used time, and pulling forceSupport can be born external load effect, avoids increasing the burden of pillar. And steel plate wall only with frameThe connection of setting a roof beam in place, the defect of having avoided four limit junction steel plate walls not punch, so can well doFor lateral resistant member is applied in many high-rise steel structure.
