Energy-consuming frame joint for steel structure beam-column connection
The invention relates to an energy-consuming frame joint for steel structure beam-column connection. The energy-consuming frame joint comprises a steel column and a horizontal steel beam connected with the side edge of the steel column. A T-shaped energy-consuming plate is connected between the end of the steel beam and the side edge of the steel column. A reinforcing and supporting structure is arranged at the position, corresponding to the connection joint of the steel beam, in the steel column. The T-shaped energy-consuming plate comprises an end plate connected with the side edge of the steel column through bolts and a transverse plate connected with the outer edge of the steel beam in the horizontal direction through bolts. The two sides of the end plate and the two sides of the transverse plate are welded and fixed. The transverse plate is sequentially provided with an expanding wing section, an anti-buckling restraining section with the reduced plate width and an outer wing connecting section from the connecting end to the outside. The outer wing connecting section is provided with a plurality of connecting holes. The expanding wing section and the end plate have the same width, the width of the expanding wing section is larger than the width of the outer wing connecting section, the width of the anti-buckling restraining section is smaller than the width of the outer wing connecting section, and the width of the expanding wing section is gradually decreased in the direction towards the anti-buckling restraining section. The outer edges of the two ends of the anti-buckling restraining section are in concave arc transition connection with the outer edge of the tail end of the expanding wing section and the outer edge of the front end of the outer wing connecting section.
本发明涉及一种用于钢结构梁柱连接的耗能框架节点，包括钢柱和与钢柱侧缘连接的水平的钢梁，钢梁的端部与钢柱侧缘之间连接有T形耗能板，钢柱的内部与钢梁连接节点对应的位置设有加强支承结构，T形耗能板包括与钢柱的侧缘螺栓连接的端板和与钢梁水平方向的外缘螺栓连接的横板，端板与横板之间双侧焊接固定，横板从连接端向外侧依次设有扩翼段、板宽缩小的防屈曲约束段和外翼连接段，外翼连接段设有若干连接孔，扩翼段与端板同宽度并且扩翼段的宽度大于外翼连接段的宽度，防屈曲约束段的宽度小于外翼连接段的宽度，扩翼段的宽度向防屈曲约束段方向逐减，并且防屈曲约束段两端的外缘分别与扩翼段未端外缘和外翼连接段前端的外缘凹弧过渡连接。
