The application discloses a computer-aided design intersection analysis method based on a Transformer and a feature column, and belongs to the technical field of CAD and artificial intelligence intersection. The method comprises the following steps: randomly generating a polynomial equation set of a parametric curve or surface, constructing Wu feature column data set and pseudo division data set; training a Transformer model to obtain a pseudo division model, and fine-tuning to obtain a Wu feature column model; converting input CAD geometric object parameter equations into a polynomial equation set, inputting the Wu feature column model to obtain an implicit equation; according to an intersection type judgment criterion, completing intersection analysis between curves and curves, surfaces and surfaces, and curves and surfaces, and outputting intersection points, intersection lines or compliance reports. The application combines symbolic computation and deep learning, and significantly improves the automation level and calculation efficiency of the CAD geometric intersection task.

This invention discloses a concrete column model and its casting method, as well as a method for testing the buckling of reinforcement in the model. The concrete column model includes a column body, with the middle part of the column body serving as the testing section. The two ends of the testing section are the upper end and the lower end, respectively. The testing section, the upper end, and the lower end are integrally cast. At least one first hard plate is provided on the joint surface between the testing section and the upper end, and at least one second hard plate is provided on the joint surface between the testing section and the lower end. The beneficial effects of this invention are: the upper and lower end regions of the concrete column are constrained by denser stirrups, and additional constraints are provided on the outer sides of the upper and lower end regions using carbon fiber cloth (or steel plates, etc.). This allows the concrete failure and longitudinal reinforcement buckling to be controlled in the middle region (i.e., the testing section), thereby avoiding the randomness of the failure area and failure mode, and is beneficial for reflecting the interaction between reinforcement and concrete.

The application discloses a column section information table generation method, which comprises the following steps: after obtaining column numbers and axial network coordinates, determining a plurality of first column models, obtaining column top elevation data of each first column model, and generating first sorting data after sorting in floor sequence; obtaining section numbers and distribution numbers of each first column model, respectively sorting in the order of elevation data to generate second sorting data and third sorting data; establishing a blank preset information table on an overall column positioning map, filling the column numbers, axial network coordinates, first sorting data, second sorting data and third sorting data into the blank preset information table, generating a column model information table and displaying; through the application, the description of all sections and reinforcement information of the same type of column can be completed on an overall column positioning map according to the generated column model information table.
