Double-core-board buckling-restrained brace structure and design method
The invention provides a double-core-board buckling-restrained energy-dissipation supporting structure and a design method, and belongs to the technical field of building structure damping. The double-core-board buckling-restrained energy-dissipation supporting structure comprises a first core board, a second core board and rib plates, and the first core board and the second core board are arranged side by side; a hollow first energy dissipation deformation space, a hollow middle elastic space and a hollow second energy dissipation deformation space are sequentially formed between the first core plate and the second core plate from front to back; the rib plates comprise a middle rib plate and side rib plates arranged on the two sides of the middle rib plate, and the middle rib plate and the side rib plates are arranged in the middle elastic space and connected with the first core plate and the second core plate; and the orthographic projection of the middle rib plate and the orthographic projection of the side rib plate are coplanar. The first core plate and the second core plate can provide large yield bearing capacity on the premise that a thick steel plate is not adopted, and the first energy dissipation section and the second energy dissipation section are not subjected to welding operation, and under the condition that the yield bearing capacity is determined, flexible adjustment of the axial rigidity can be achieved by changing the number of the middle rib plates and/or the number of the side rib plates.
本发明提出了一种双芯板防屈曲耗能支撑结构及设计方法，属于建筑结构减震技术领域，包括第一芯板、第二芯板和肋板，第一芯板和第二芯板并排设置，第一芯板和第二芯板之间自前往后依次形成空心状的第一耗能变形空间、中间弹性空间和第二耗能变形空间；肋板包括中间肋板和设置在中间肋板两侧的侧部肋板，中间肋板和侧部肋板均设置在中间弹性空间内，且均与第一芯板和第二芯板连接；中间肋板的正投影与侧部肋板的正投影共面。本发明的第一芯板和第二芯板可以在不采用厚钢板和第一耗能段、第二耗能段均无焊接作业的前提下提供较大的屈服承载力，而在屈服承载力确定的情况下，可以通过改变中间肋板的数量和/或侧部肋板的数量实现轴向刚度的灵活调整。
