A beam end variable cross-section connecting joint device
By designing a variable cross-section connection node device at the beam end, and utilizing a combination of I-beam connecting beams and trapezoidal webs, the problems of insufficient bearing capacity at the beam end of the wall column and complex construction were solved. This achieved efficient torque transfer and plastic hinge displacement, thereby improving the structural stress and seismic performance.

AI Technical Summary
In wall-type column structures, the reduction in the weld length of the beam end flange makes the core area of the node prone to damage such as weld tearing and flange buckling. Existing remedial measures increase construction complexity and may create new weak links.
A variable cross-section connection node device is adopted at the beam end. The connection between the beam and the steel column is fixedly connected. The cross-section is designed as an I-shaped cross-section, and the connection height is increased by using a trapezoidal web. Combined with a hybrid connection method of full welding and bolt welding, the efficient transmission of torque and the outward movement of plastic hinge are achieved.
It improves the structural stress and seismic performance, simplifies construction procedures, reduces costs, meets the design principle of strong nodes and weak components, and improves construction efficiency and safety.
