Method for calculating tearing path of all-welded steel truss girder node with bevel edge on one side and arc edge on one side

The invention relates to the technical field of bridge structures, in particular to a method for calculating a tearing path of a node of an all-welded steel truss girder with a bevel edge on one side and an arc edge on the other side, which comprises the following steps: according to web member structure parameters, bevel edge parameters, arc edge parameters and the position relationship between a web member and the bevel edge and the arc edge, calculating the tearing path of the node; establishing a distance function from the fixed point to the bevel edge, a distance function from the fixed point to the arc edge, a contribution function of the web member horizontal plates to tearing and a tearing path value of a node plate between the web member horizontal plates; and according to the distance function from the fixed point to the bevel edge, the distance function from the fixed point to the arc edge, the contribution function of the horizontal plate of the web member to tearing and the tearing path value of
