Segmented tooth-shaped constrained energy dissipation joint
The invention belongs to the technical field of steel structures, and provides a segmented tooth-shaped constrained energy dissipation joint. The segmented tooth-shaped constrained energy dissipation joint comprises a column, a long beam section, a short beam section and an energy dissipation section, wherein the long beam section and the short beam section are connected by virtue of the energy dissipation section through a high-strength bolt group, the energy dissipation section comprises a flange connecting piece and a web connecting piece, energy is dissipated by means of yielding of an energy dissipation plate, and a constrained jacket with a tooth-shaped bulge is arranged on the flange connecting piece. Under the earthquake, the plastic deformation of the structure can be controlled on the energy dissipation section, and additionally, the tooth-shaped constraint exists, so that the condition that the energy dissipation performance is reduced due to excessive buckling of the energy dissipation section is avoided, and main components of the structure always keep elastic. The joint has the advantages of good energy dissipation effect, small overall size, no influence on the structural space layout, the simple structure and easiness and convenience in machineing, and the structure can be recovered for use only by replacing the energy dissipation section during post-earthquake repair.
本发明属于钢结构技术领域，提供了一种分段式齿状约束耗能节点，包括柱、长梁段、短梁段、耗能段。长梁段和短梁段由耗能段通过高强螺栓群连接。耗能段包括翼缘连接件和腹板连接件，依靠耗能板屈服耗散能量，翼缘连接件设有带齿状凸起的约束外套。地震下，结构的塑性变形能控制在耗能段上，同时由于齿状约束的存在，又不至于导致耗能段屈曲过度，引起耗能性能下降，保证了结构的主要构件始终保持弹性。本节点耗能效果良好，节点整体尺寸较小，不影响结构空间布局，构造也较为简单，加工简便，震后修复时，只需更换耗能段即可使结构恢复使用。
