The invention discloses an H-shaped column weak shaft connection joint structure and a connection method. Two lateral stiffening ribs arranged in parallel are arranged between two column flanges of anH-shaped column, and the plane on which the largest surfaces of the lateral stiffening ribs are located is simultaneously perpendicular to the plane on which the largest surfaces of the column flanges are located and the plane on which the largest surface of a column web plate is located; side plates are welded on the H-shaped column, and the plane on which the largest surfaces of the side platesare located and the plane on which the largest surface of the column web plate is located are in a same plane; and in the weak shaft direction of the H-shaped column, flange expanding plates are arranged on both sides of beam flanges of an H-shaped beam, the end surfaces of the beam flanges and the end surfaces of the flange expanding plates are welded to the other side surfaces of the side plates, and both side edges of each flange expanding plate are flush with both side edges of each side plate, so that when the force in the weak shaft direction is transmitted to the column flanges, risingarcs and falling arcs of welding seams are moved from the positions with peak stress to the parts with less stress to reduce the risk of brittle fracture of the welding seams of the beam flanges. TheH-shaped column weak shaft connection joint structure has the distinct characteristics of strong joints and weak members, the outward movement of plastic hinges on the beam under the action of reciprocating loads can be realized, and the requirements of the ductility and bearing performance of a joint are increased.
本发明公开了一种H型柱弱轴连接节点结构及连接方法，通过在H型柱的两个柱翼缘之间设置两个平行设置的横向加劲肋，横向加劲肋最大面所在平面同时垂直于柱翼缘最大面所在平面和柱腹板最大面所在平面；在H型柱上焊接侧板，侧板最大面所在平面与柱腹板最大面所在平面在同一平面内；在H型柱弱轴方向上，在H型梁的梁翼缘两侧设置扩翼板，梁翼缘和扩翼板的端面与侧板的另一个侧面焊接，扩翼板的两侧边与侧板的两侧边平齐，使得弱轴方向传力至柱翼缘时，将焊缝的起、落弧从应力峰值处移至应力较小部位，以减小梁翼缘焊缝脆断的风险，本结构具有鲜明的强节点弱构件的特征，在往复荷载作用下可以实现梁上塑性铰外移，增加节点的延性和承载性能的需求。
