Description
Technical field
The utility model relates to building field, and especially fabric structure supports the field, particularly, relates to and in architectural structure system, is used to the buckling-restrained bracing member that supports.
Background technology
Buckling-restrained support is claimed not have bonding again and is supported; It is a kind of novel earthquake-proof power consumption member of superior performance; A kind of drawn with the pressurized situation under can both reach the energy-consumption supporting member of surrender, improved the shortcoming that flexing takes place when tradition is supported on pressurized, improved the anti-seismic performance of structure.
Frame construction is that highrise building uses more general a kind of form of structure, but its anti-side rigidity and supporting capacity are limited, under wind load or geological process the side direction displacement bigger, make its construction height receive certain limitation.For anti-side rigidity of solution framework structure and the more weak problem of intensity, can be its additional support, be framework-support system, comprise center support-frame system and eccentric support-frame system.Eccentric support-frame system has been sacrificed part agent structure member through beam-ends shear yielding section dissipation earthquake input energy, make its shake back repair comparatively difficulty, and cost is very high.And center support-frame system under geological process, is difficult to avoid supporting the pressurized flexing.After conventional steel supported flexing, performance degradation was serious, the destruction of very easily causing support itself to be connected with node, and then cause structural seismic capacity sharply to descend, very unfavorable to structural seismic.For avoiding ordinary steel to support the generation of pressurized flexing phenomenon, there is the scholar to propose this notion of buckling-restrained support, be also referred to as " anti-flexing supports " or " not having bonding supports ", be common support and apply lateral restraint, produce flexing when preventing its pressurized.Buckling-restrained supporting form is various, but operating principle is similar, and its power is born by the supporting core unit, and peripheral steel pipe or concrete filled steel tube provide constraint to core, limit its complete buckling and cripling.Buckling-restrained support tensile and compressive property is suitable; Hysteresis loop is full stable, and it not only can be used as structural element, also is a kind of damper of function admirable after the surrender; The earthquake that can dissipate in a large number input energy; And the damage of structure concentrated on buckling-restrained support self, and protected agent structure, reduced the structure seismic response.Buckling-restrained support structure form both domestic and external can be divided into two types substantially at present: the buckling-restrained support of (1) clean steel type; (2) with the concrete filled steel tube be the buckling-restrained support of constraint element.But existing buckling-restrained support is very uneconomical, and cost of manufacture is higher, and this is that common way is the enlarging section area owing to need in the design to guarantee that the support node position is in elastic stage.The power consumption core and the support node that support adopt same steel plate, have caused a large amount of waste materials inevitably; On the other hand,, also can cause the support outward appearance to control sometimes, have to increase sleeve dimensions, and be only most economical rational by the design of stable control by Intensity Design owing to the cross dimensions that increases position of joints.
