Current codes and standards have many regulations regarding the arrangement of structural columns, which are generally reviewed manually line by line to identify any non-compliant arrangements. A typical design may contain hundreds of structural columns, and the arrangement of these columns could potentially exhibit at least four types of non-compliance, making manual review obviously time-consuming and labor-intensive. Summary of the Invention

[0044] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] like Figure 1 As shown, the present invention provides a method for arranging structural columns, including:

[0046] Step 1: Generate a design model for the layout of structural columns, and then extract the set BW = {bw} of all brick walls in the design model. i The set of all structural walls SW = {sw} i}, and store the coordinates of the two endpoints of the centerlines of the brick walls and structural walls; then extract the set BC = {bc} of all structural columns in the design model. i The set of all structural columns SC = {sc} i} and store the coordinates of the center of the cross-section of the structural columns and the building columns;

[0047] Here, as Figure 2 Information technology methods can be used to express the design scheme of structural column layout (e.g., to create a BIM floor model that includes structural columns);

[0048] Step 2: Based on the set of all brick walls BW = {bw i The set of all structural walls SW = {sw} i The coordinates of the two endpoints of the centerlines of the brick walls and structural walls, and the set of all structural columns BC = {bc} i The set of all structural columns SC = {sc} i Given the coordinates of the cross-section centers of the structural columns and the building columns, find the set of critical nodes T = {t}. i And calculate the priority, where i represents the number of the brick wall, brick wall, structural column, structural column or key node;

[0049] Preferably, the set of key nodes T includes six categories:

[0050] (1) Each brick wall bw i The two endpoints have a priority of 1.

[0051] (2) The intersection of brick walls, i.e., BW*BW, has a priority of 2;

[0052] (3) Each structural column bc i Its priority is 3;

[0053] (4) The intersection of the structural wall and the brick wall, i.e., SW*BW, has a priority of 4;

[0054] (5) Each structural column sc i Its priority is 5;

[0055] (6) Each structural wall sw i The two endpoints have a priority of 6.

[0056] Step 3: Merge key nodes in the same position;

[0057] Preferred, such as Figure 3 As shown, key nodes t are paired up. h and t j If t h to t j If the distance is less than 0.1 meters, then delete t from T. h and t j At the same time, add a new key node t in T. k The added key node t k The coordinates are t h and t j Average coordinates, key node t k The priority is t i and t j The one with the higher priority has the effect of merging two key nodes into one; where h, j, k∈i, this step is repeated until no two key nodes can be merged.

[0058] Step 4: Pair up key nodes t h and t j Determine t h and t j Is there a brick wall between them? i If t h and t j There is a brick wall between them. i Then the key node t h and t j Connect them with an edge so that the set of key nodes and edges forms a topological graph structure G;

[0059] Preferably, the key node t is determined. h and t j Is there a brick wall between them? i ,include:

[0060] like Figure 4 As shown, the set of brick walls BW = {bwi} is iterated through, and based on the coordinates of the two endpoints of the centerline of the brick walls, if the key node t i and t j All are at the same distance from the brick wall. iIf the distance between the centerlines is less than 0.1 meters, then it is determined that there is a brick wall between the critical nodes. i .

[0061] Step 5: Based on the topological graph structure G, check whether the arrangement of the structural columns is qualified.

[0062] Preferably, four structural column arrangement schemes can be tested. For example... Figure 5 , 6 7.

[0063] (1) As shown in 5, traverse the set of key nodes T. If there is a key node t m Each critical node is connected to only one other critical node by a single edge, and the critical node t m If the priority is 1, then the critical node t m The wall end of the brick wall; based on the coordinates of the center of the cross-section of the structural column, if the critical node t is determined... m Without structural pillars and stronger constraints, the critical node t m The test result is t m There is a lack of structural columns at the end of the wall, m∈i;

[0064] (2) Figure 5 As shown, traverse the set of key nodes T, if there is a key node t n If the priority is 2, then the critical node t n The intersection of the brick walls; based on the coordinates of the center of the cross-section of the structural column, if we determine the critical node t... n Without structural pillars and stronger constraints, the critical node t n The detection conclusion is that the key node t n The intersection point lacks a construction pillar, n∈i;

[0065] (3) Figure 6 As shown, iterate through all key nodes t with priority 3 in the key node set T. p Using Dijkstra's algorithm, based on the coordinates of the cross-section center of the structural column, the critical nodes t in the topological graph G are calculated. p The shortest distance to other structural columns; if any distance is less than 1.0 meter, then this critical node t... p The test result is t p The structural columns are too dense;

[0066] (4) Figure 7 As shown, iterate through all key nodes t with priority 3 in the key node set T. q Dijkstra's algorithm is used to compute the critical nodes t in the topological graph G. qThe shortest distance to key nodes with priorities of 3, 4, 5, and 6 is used to mark the set of key nodes T and the thickness and height of the associated brick and structural walls. Specifically, if the brick and structural walls are 200mm thick, all shortest distances are set to be greater than 5.0 meters; if they are 100mm thick, all shortest distances are set to be greater than 4.0 meters; if all shortest distances are greater than 2H, where H is the thickness and height of the associated brick or structural wall, then the detection conclusion is t. q The structural columns are too far apart.
