Description
Technical field
The utility model belongs to construction engineering technical field, relates to a kind of steel performance, is specifically applicable to the through concrete-filled steel square tubular column of a kind of stiffener in multi and tall steel building and H profile steel beam structures with semi-rigid joints.
Background technology
U.S. Northbridge in 1994 earthquake in succession occurred and nineteen ninety-five Japan Kobe earthquake etc. repeatedly earthquake show, adopt the steel frame welding rigid joint completely because ductility of joint is poor, residual stress is large, easy generation brittle fracture, thus cause earthquake zone steel building disaster quite serious.In recent years, concrete-filled rectangular steel tube because of joint form simple, second moment of area is large, good stability, be convenient to particular advantages such as taking precautions against fire, applies increasingly extensive.But these concrete-filled rectangular steel tube frame construction joint structures are close with steel framed structure, therefore, also there is the problems such as ductility of joint difference, welding residual stress be large, under geological process, equally easily occur brittle fracture.
At present, varied rigid link couples together beam, post mainly through high-strength bolt and connector (angle steel, T-steel and end plate), and principal mode has the board-like connection of through, the not through overhanging end of bolt, and flange of beam is connected with post jamb by connector.(1) the not through overhanging end of bolt is board-like, namely the high-strength bolt that the girder steel of welded end plate is welded on steel pipe post jamb by bolt is connected with post, this node is easy to the cripling causing steel pipe post jamb, and the bolt Welding quality requirement of high-strength bolt and post jamb is high, switching performance not easily ensures, bending rigidity is also little, therefore less in the application of engineering reality.(2) the through overhanging end of bolt is board-like, namely girder steel is by welded end plate or T-steel (T-shaped connector also can be connected with girder steel with high-strength bolt), be connected with post by the strength bolts of growing tall of through shaft, after the concrete in pipe reaches some strength, to shank of bolt Shi Hanzhang.This node has good ductility and anti-seismic performance, and connection stiffness is large, but the installation of building site in-and-out bolt, the prestressed applying of bolt and control are more difficult, and because bolt needs to run through steel core concrete column, site operation is also very inconvenient.(3) connector formula, namely pass through connector (angle steel, T-steel and combined steel plate) and be connected with steel core concrete column with high-strength bolt, web is connected with post by the vertical steel plate high-strength bolt be welded on post.The flange of beam of this node, because have employed high-strength bolt, not only increases ductility and the anti-seismic performance of node, and decreases Site Welding amount, is also conducive to on-the-spot installation.But when connector is under seismic loading repeatedly, owing to there is no internal partition power transmission in steel pipe.Steel core concrete column easily causes the cripling of post jamb.
Research shows, the deformability that Semi-rigid Connection Steel Frame is stronger because node has and energy dissipation capacity, can the natural vibration period of extending structure, can to dissipate seismic energy by controlling beam-ends plastic hinge, prevent because connected node destroys and cause collapsing of structure, thus greatly reduce earthquake, be conducive to antidetonation.Therefore research structures with semi-rigid joints new model, realize seismic design the applying in Practical Project of ductility joint, significant.
