Abstract

Abstract

Diamond grid braced frames structure(DBF) is a new type of lateral force support structure, which can be used in multi-high-rise steel structure housing to facilitate the installation of enclosure wall.In order to verify the seismic performance of diamond grid brace, the finite element quasi-static analysis of single-span two-story diamond grid braced structure was carried out, and compared with the traditional single diagonal bar brace, herring-bone brace and cross brace under the same steel consumption.The results showed that the diamond grid braced was not prone to buckling failure, and the structure had good ductility and stiffness without increasing the amount of steel.The diamond grid braced structure had adverse effects on the frame, especially on the side columns. Therefore, according to the basic assumptions of structural mechanics, considering the adverse effects of the diamond grid braced structure on the side columns, a design method for diamond grid braced structure was proposed, which could be used as a reference for practical engineering.
