Semi-rigid steel frame beam-column joint based on buckling-restrained steel plates
The invention discloses a semi-rigid steel frame beam-column joint based on a buckling-restrained steel plate. A key stress component of the joint is a T-shaped steel plate with a weakened section. The buckling of the T-shaped steel plate when the T-shaped steel plate is pressed can be prevented by the joint constraint of the buckling-restrained angle steel and the beam flange, so that the T-shaped steel plate has stable compression performance and full hysteretic behavior. The node is simple and clear in mechanical principle, the rigidity and the strength are determined by the length and the sectional area of the weakening section of the T-shaped steel plate, and design is convenient. And the T-shaped steel plates and the buckling-restrained angle steel are mounted on the inner sides of the beam flanges, so that the influence on a building space and a floor slab is reduced. The joint is assembled by bolts and is convenient to mount and dismount. When an earthquake occurs, plastic deformation of the joint is concentrated on the weakening section of the T-shaped steel plate, the beam and the column are in an elastic state, and only the damaged T-shaped steel plate needs to be replaced after the earthquake ends.
本发明公开了一种基于防屈曲钢板的半刚性钢框架梁柱节点，该节点的关键受力构件是具有削弱段的T型钢板。防屈曲角钢和梁翼缘的共同约束可防止T型钢板在受压时屈曲，使其具有稳定的受压性能和饱满的滞回行为。该节点的力学原理简单、明晰，其刚度和强度由T型钢板削弱段的长度和截面积确定，方便设计。T型钢板和防屈曲角钢均安装在梁翼缘内侧，减少了对建筑空间和楼板的影响。该节点全螺栓装配而成，便于安装和拆卸。地震发生时，节点的塑性变形集中于T型钢板的削弱段，梁和柱处于弹性状态，地震结束后，仅需更换受损的T型钢板。
