Description
Technical field
The present invention intersects steel core concrete column tubular joint, particularly relates to low-angle and intersects Frame Joints of Concrete-Filled Steel Tube.
Background technology
Encased structures can improve the anti-seismic performance of structure when significantly not increasing cost, reduce the sectional dimension of component, progressively be promoted in highrise building and applied at present, have good overall economic efficiency, the development of highrise building makes it have wide prospect.
The most outstanding feature of concrete filled steel tube Diagonal Frame Structure is that its urceolus is made up of the batter post of bidirectional crossed continued circling outer surface of building, the vertical post that instead of traditionally adds the form of skewed horizontal load, has the advantage that material use efficiency is high, rigidity is large, lateral resistance is good.Due to the architectural effect of its uniqueness, this form of structure is subject to the favor of architects increasingly.
Few to the theoretical research of Diagonal Frame Structure at present, but the application in Practical Project is carried out.Such as Guangzhou TV transmission tower, Guangzhou West Tower, Central Bank of Kuwait mansion, design and produce processing for intersection Frame Joints of Concrete-Filled Steel Tube and also there is many difficult points.
Chinese regulations " concrete filled steel tube design and construction code " (CECS28) gives the calculating of concrete filled steel tube section bearing capacity, and American Standard AISC360-05 give also circular steel tube concrete and concrete-filled rectangular steel tube section bearing capacity computational methods.But basis is not had for the section form of this X node middle part energetically plate.
Although " Code for design of steel structures " and " steel tubular structure tecnical regulations " has done ask for something to pipe pipe tubular joint in steel tubular structure, angle between supervisor and arm should not be less than 30 °, adopt fillet weld between arm and supervisor more, or the fillet weld of band groove.But intersection steel core concrete column stiffened RHS joints mostly generally is symmetrical nodes, two tube section diameter are equal, regardless of primary and secondary, and the welded K-joint of steel tubular that connected node neither be traditional.Thickness of section is comparatively large, can not use the fillet weld of thin-wall steel tube.Meet the requirement of bearing capacity, need to adopt groove full penetration weld.
7.1.1 the 2nd article regulation in " steel tubular structure tecnical regulations " " be responsible for and angle between arm or two arm axis should not be less than 30 ° ", and actual in structure design inevitably uses the low-angle rod member being less than 30 degree, larger difficulty is caused to joint structure design and construction.
" experimental study of Guangzhou West Tower giant bias grid plan tubular joint " literary composition proposes a kind of low-angle pipe fitting crossover node tubular joint, it utilizes vertical oval arm-tie and horizontal annular stiffener to realize the making of this tubular joint, but this belongs to outer method of putting more energy into, and cannot meet the requirement to outward appearance in some architectural design.
