Prestressed concrete-filled steel tube buckling-restrained supporting member
The invention relates to a prestressed concrete-filled steel tube buckling-restrained supporting member, comprising a concrete-filled steel tube buckling-restrained supporting member. The prestressed concrete-filled steel tube buckling-restrained supporting member is characterized by further comprising prestressed cables; four prestressed cables are evenly distributed on the circumference of a core dissipative member along full length of the supporting member; at two ends of a peripheral restraining member, the prestressed cables apply prestress to concrete. The peripheral restraining member extends out from the end of the core dissipative member of the buckling-restrained supporting member; section is enlarged, an extension of great flexural rigidity is formed; the extension is hinged to or rigidly connected with a frame member through connecting boards and high-strength bolts. After the concrete is prestressed, the problem of early cracking of the concrete caused by bending of the peripheral restraining concrete-filled steel tube member is solved, the flexural rigidity of the peripheral retraining member is never decreased due to tensile cracking of the concrete, the characteristic, namely high compressive bearing capacity, of the concrete is made full use, and bearing capacity of the buckling-restrained supporting member is improved.
