High-strength steel column-common steel beam steel brace-low-yield-point steel coupling beam restorable structure

Abstract

The invention discloses a high-strength steel column-common steel beam steel brace-low-yield-point steel coupling beam restorable structure which comprises a low-yield-point steel coupling beam, a common steel brace, a common steel framed beam and a high-strength steel framed column, wherein one end of the low-and-medium-yield-point steel coupling beam in each layer is connected with the common steel framed beam, the other end of the low-and-medium-yield-point steel coupling beam is connected with another common steel framed beam or the high-strength steel framed column; the upper end of the common steel brace is connected with the end part of the common steel framed beam, the lower end of the common steel brace is connected with a connecting node of another common steel framed beam or themiddle part of another high-strength steel framed beam; and one end of the common steel framed beam is connected with the low-yield-point steel coupling beam, and the other end of the common steel framed beam is connected with high-strength steel framed column or another low-yield-point steel coupling beam. The high-strength steel column-common steel beam steel brace-low-yield-point steel coupling beam restorable structure not only can meet the rigidity and strength demand of the structure, but also can effectively ensure that a gradient energy dissipation mechanism with good ductility is formed under the geological process, and the antiseismic performance and function restorability of the overall structure system can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of structural engineering steel structures, in particular to a resettable structure of high-strength steel column-common steel beam steel support-low yield point steel connecting beam. Background technique [0002] With the construction of a large number of multi-high-rise and super high-rise buildings, steel structures have been widely used at home and abroad. The traditional steel structure systems commonly used in structural design today include pure steel frames, steel frames with central supports, steel frames with eccentric supports, and steel frames with steel plate shear walls. At the same time, the development and improvement of steel production technology has made it possible to produce and apply new low-yield point steels and high-strength steels. However, the existing design codes in our country have not given clear regulations or guidance on how to apply this new type of steel to the steel stru...
