Abstract

The invention discloses a buckling restrained brace structure arrangement system for a building, which comprises a frame column, a frame beam, four buckling restrained braces and a connecting node element, a rectangle is enclosed between the frame column and the frame beam, and the connecting node element is arranged between the frame column and the frame beam. The two ends of each buckling restrained brace are fixed to the middle of the frame column and the middle of the frame beam through connecting joint elements respectively, and a rhombic building window opening is defined by the four buckling restrained braces. The buckling restrained brace arranged in the rhombus mode is adopted, the good anti-seismic performance is achieved, construction is convenient and fast, the steel using amount of embedded parts is reduced, good feasibility and practicability are achieved, and the buckling restrained brace can be used for concrete structures, steel structures and combined structures. The structure is simple, force transmission is clear, and construction is fast.

Description

technical field [0001] The invention relates to structural shock-absorbing buildings, in particular to a buckling-constrained support structure arrangement system for buildings. Background technique [0002] As we all know, my country is an earthquake-prone country. With the continuous development of academic research and engineering technology in the field of earthquakes in my country, the seismic performance of buildings has been greatly improved. In recent years, buckling-constrained braces are increasingly used in engineering and have achieved remarkable results. Buckling-restrained braces are connected to frame beams and frame columns through connection nodes, and the connection performance of connection nodes often affects the seismic performance of frame beams and frame columns. [0003] At present, the common method of connecting nodes is to extend the gusset plate and embed it at the node of the frame beam and column, or just connect it to the beam end. When the g...
