Analysis of a New Wedge-Shape Rectangular Tube Column and Girder Connection Joint

Aiming at the existing problems of column-beam joint put forward the new wedge-box joint. The new joint shape is simple, avoid the inconvenience that add diaphragm in the square tube, as well as to the late process of building interior decoration, the way of joints force transmission is clear, mechanical and seismic performance is good, from the external shape is better than the traditional internal partition and outreach plate joints, and compare to the both, inner bearing capacity is not weak, it can satisfy the need of industrialization of steel structure well, and used in actual engineering design.
