The invention provides a cross support structure with a middle energy dissipation plate. The cross support structure comprises a portal steel frame, an energy dissipation plate located in the portal steel frame, and four support segments forming an X shape; and one end of each support segment is connected with the energy dissipation plate, and the other end of each support segment is connected with the portal steel frame. Seismic energy is consumed by plastic deformation of the energy dissipation plate intensively, so that the plastic deformation of the portal steel frame is smaller; and thus,the anti-seismic property of the portal steel frame is improved. Meanwhile, through adding of the energy dissipation plate on the basis of an existing central support structure, the cross support structure has the advantages of high strength and stiffness of the central support structure and high ductility and energy dissipation capability of an eccentric support structure, and is of great significance in promotion of application of a steel frame support structure to a high intensity fortified area.
本发明提供了一种带中部耗能板的交叉支撑结构，包括：门形钢框架；耗能板，位于所述门形钢框架内；四个构成X形的支撑段，每个所述支撑段的一端连接所述耗能板，另一端连接所述门形钢框架。利用耗能板的塑性变形集中消耗地震能量，使得门形钢框架的塑性变形较小，从而提升了门形钢框架的抗震性能。同时，通过在现有中心支撑结构的基础上增加了耗能板，使所述交叉支撑结构兼具中心支撑结构的高强度和高刚度以及偏心支撑结构延性好和耗能能力强的优点，对于推广钢框架支撑结构在高烈度设防区域的使用具有重要意义。
