Recoverable assembly type steel frame combined negative stiffness supporting lateral force resisting wallboard
The invention discloses a recoverable assembly type steel frame combined negative stiffness support lateral force resistant wallboard, which comprises a steel frame, a negative stiffness support, an external fireproof decoration layer and a connecting piece, and is characterized in that the steel frame comprises a steel frame column, a steel frame beam and a column foot stiffening rib; the steel frame beam and the negative stiffness support are connected through a connecting piece to form a beam support integrated component, the two ends of the steel frame beam in the beam support integrated component are connected with the upper end of a steel frame column respectively, the column top is higher than the surface of an upper flange of the steel frame beam, and column foot stiffening ribs are arranged on the outer sides of column feet of the steel frame columns. And an externally-hung fireproof decoration layer is installed to form the recoverable assembled steel frame combined negative stiffness supporting lateral force resisting wallboard. The problems that a traditional steel frame combined inner diagonal bracing wall plate is plastically damaged after strong shock and is difficult to repair are well solved, and the steel frame combined inner diagonal bracing wall plate can be used as a basic structural component in an assembly type recoverable structure.
本发明公开了一种可恢复的装配式钢框架组合负刚度支撑抗侧力墙板，包括钢框架、负刚度支撑、外挂防火装修层、连接件，所述钢框架包括：钢框柱、钢框梁、柱脚加劲肋；所述钢框梁和负刚度支撑通过连接件连接组成梁支撑一体式构件，梁支撑一体式构件中钢框梁两端分别与一钢框柱上端连接且柱顶高于钢框梁上翼缘表面，钢框柱柱脚外侧设有柱脚加劲肋；安装外挂防火装修层形成可恢复的装配式钢框架组合负刚度支撑抗侧力墙板。本发明较好地解决了传统钢框架组合内斜撑墙板经强震后塑性破坏且难以修复的问题，可做为装配式可恢复结构中的基本结构构件使用。
