While the temporary support unloading process is a structural system transition process in which the structure transitions from a construction state to a design state. The stress state in the construction stage is very different from the final design stress state: in the state of the supporting jig frame, the dead weight of the supporting jig frame is basically born by the supporting jig frame; when the support frame is disassembled, the structure is displaced downwards due to dead weight, and the internal force of the rod piece is redistributed, so that the structure is changed greatly in the moment. In addition, in the actual construction process, all temporary supporting jig frames cannot be synchronously dismantled, and the internal force born by the supporting jig frames after being dismantled one by one can possibly undergo a gradual increasing process, so that the requirement on the structural strength of the supporting jig frames is high, and the construction is difficult.
