    Abstract
  • To ensure the construction safety of high-formwork support structures, a set of construction intelligent real-time monitoring method based on computer vision and finite element technology was proposed. A refined finite element model was established according to the real situation of the rods arrangement of the high-formwork support structure, and the buckling analysis was carried out under a variety of working conditions, so as to obtain the vertical displacement of the key joints during the buckling damage of the high-formwork support structure, and to obtain the alarm threshold value of the intelligent real-time monitoring of the construction. The intelligent real-time monitoring algorithm based on computer vision was developed to monitor the displacement changes of the high-formwork support structure in the construction process in real time, and the algorithm will automatically alarm and guide the elimination of dangers and the protection of construction safety when unsafe displacement occurs. After the construction, according to the theoretical calculation results and the actual measurement results, the finite element model was corrected parametrically, and the corrected finite element model was subjected to buckling damage analysis, and the sizes of the corrected buckling vertical displacement and the alarm threshold were compared to illustrate the reasonableness of the alarm threshold. The successful completion of a high-formwork support structure project for a multi-use building verified the effectiveness of the new construction monitoring method proposed in the paper.
