Step S307, position information of the three-dimensional civil structure model and each second object in the three-dimensional civil structure model is obtained.
It should be noted that the second object may be a space structure capable of bearing a load, for example: plates, beams, columns in civil structures.
In step S308, a second spatial bounding box of each second object is obtained.
Wherein obtaining the second spatial bounding box of each second object may include:
for each second object, determining the area occupied by the second object according to the position information of the second object; and expanding the preset range to the periphery by using the area occupied by the second object to obtain a second space bounding box of the second object.
It should be noted that the second space bounding box refers to a certain three-dimensional space, when the preset range extending to the periphery is 0, the second space bounding box of the second object may be a space region occupied by the second object, and when the preset range extending to the periphery is not 0, the second space bounding box of the second object may be a space region extending to the periphery by the preset range occupied by the second object.
Step S309, according to the three-dimensional civil structure model, the position information of each second object, the layer height of each load point and the second space bounding box of each second object, moving each load point to the corresponding second object and associating the load information of the load point to the corresponding second object, so as to generate the three-dimensional civil structure model marked with the load information.
The method for generating the three-dimensional civil structure model marked with the load information according to the three-dimensional civil structure model, the position information of each second object, the layer height of each load point and the second space bounding box of each second object comprises the following steps of S3091-S3096, as shown in fig. 4:
s3091, for each load point, moving the position of the load point along the layer height direction to a layer corresponding to the layer height of the load point.
In the three-dimensional civil structure model, a spatial coordinate system is established, and the direction of the layer height in the spatial coordinate system generally refers to the direction in which the z coordinate axis is located.
For any load point P1 with position coordinates (x1, y1, z1), moving the position of the load point P1 in the layer height direction to the layer corresponding to the layer height of the load point may be: keeping the x1 and y1 coordinates of the load point P1 unchanged, translating the z1 coordinate to the layer corresponding to the layer height z2, wherein the space coordinate of the load is P2(x1, y1 and z 2). For example: as shown in FIG. 5, which is a cross-sectional view of the three-dimensional process model in the y-z direction, the loads P1 and P2 belong to a 12.495 meter story height, so P1 is moved from point A to point A1 and P2 is moved from point B to point B1.
Step S3092, determining whether the updated position of the load point is located within the second spatial bounding box of the second object, if so, performing step S3093, and if not, performing step S3094.
Step S3093, the updated position of the load point is moved to the centroid of the second object and the updated load point is associated with the second object.
For any load point P2 with the position coordinates of (x1, y1, z2), if the load P2 is in a second space bounding box of a second object, the load point P2 is perpendicular to the centroid axis in the layer height plane of the second object, the intersection point is a vertical foot P3, then the load point P2 is moved to P3, and the updated load point and the second object are correspondingly stored. For example: as shown in fig. 6, which fig. 6 is a cross-sectional view in one x-y direction of a three-dimensional process model, assuming the bounding box is designated as the space occupying volume of the structural member, loads P1 and P2 are both within the bounding box of the structural member and P1 is on the centroid axis of the member. Therefore, the P1 position was unchanged, translating P2 from point B to point B1.
Step S3094, two second objects having the smallest distance to the updated position of the load point are determined according to the positions of the respective second objects.
It should be noted that the distance between the second object and the updated position of the load point is the distance from the load point to the axis of the second object.
S3095, decomposing the load of the load point corresponding to the updated position of the load point to two second objects on the three-dimensional civil structure model.
In the present application, as shown in fig. 6, the load point P3 is broken down into two loads, P31 and P32, the points of action being C1 and C2, respectively.
S3096, determining load information decomposed to the two second objects according to the distance between the two second objects and the updated positions of the load points, and associating the load information decomposed to the two second objects to the corresponding second objects to generate the three-dimensional civil structure model marked with the load information.
It should be noted that there are various methods for moving and decomposing the load, as long as the transmission rule of the load on the structural system is met, such as: as shown in fig. 6, the load P3 is decomposed into two loads P31 and P32, the acting points are C1 and C2, respectively, the load of P31 is P31 ═ P3 ═ b/(a + b), the load of P32 is P32 ═ P3 × (a/(a + b), where a and b refer to the distance between the load point P3 and the corresponding second object with the smallest distance, respectively.
When a line load exists, a starting point and an end point of the line load are obtained, the starting point and the end point of the line load are respectively regarded as point loads, the starting point and the end point of the line load are processed according to the moving and decomposing modes of the point loads, and load points decomposed to the same three-dimensional civil engineering component model are connected to serve as new line loads.
