High-strength steel elastic ductility control structure

Abstract

A high-strength steel elastic ductility control structure comprises stand columns made of a high-strength steel material and a structural body composed of beams horizontally arranged among the stand columns at intervals. The beams and the stand columns are connected through semi-rigid joints or hinge joints. The structural body is divided by the beams into at least one anti-seismic energy-consuming area. An anti-seismic energy-consuming device is arranged in each anti-seismic energy-consuming area. By means of the high-strength steel elastic ductility control structure, it is ensured that a high-strength steel component is in an elastic state in normal use under the effect of an earthquake, the problem that a traditional high-strength steel structural system is limitedly used in an anti-seismic fortification area due to the ductility problem is solved, the application range of the high-strength steel structure is expanded, and the advantages of the high-strength steel can be more sufficiently and effectively brought into play.

Description

technical field [0001] The invention belongs to the field of building high-strength steel structure design, in particular to a high-strength steel elastically controlled ductility structure. Background technique [0002] Improving the strength of steel helps to reduce the cross-sectional size of steel structural members and increase the effective use of space in buildings. Reducing the thickness of the plate can solve the problem of thick plate welding and ensure the quality of the weld. The use of high-strength steel can also reduce the weight of the structure, reduce the force of the superstructure on the foundation, and reduce the cost of the foundation. Due to the small self-weight of the structure, the seismic action of the structure can also be reduced in the anti-seismic fortification area. For bridges and long-span structures, the use of high-strength steel can solve the problems of transportation and hoisting of large steel components, and at the same time, due to...
