Example Embodiment
[0033] The present invention will be further explained below in conjunction with the embodiments and the drawings of the specification.
[0034] figure 1 This is the technical flow chart of the method for symmetrical force finding of the prestressed cable rod structure in the present invention, which mainly includes the following steps:
[0035] (1) According to the given initial geometric configuration of the prestressed cable and rod structure, construct the force balance matrix H of the overall structure; according to the independent symmetry operation of the cable and rod structure, the overall symmetry of the structure and the symmetry group to which it belongs are clarified, The symmetrical operations include identity transformation, rotation, mirroring, and inverse operations. Under these symmetrical operations, the geometric configuration of the structure remains unchanged. Use the group theory method to establish a symmetric subspace corresponding to the external load vect...
