Аннотация:

The object of research is a calculation model for determining the deflection of a window mullion post under the combined influence of wind load, temperature, and climatic factors. Method. The calculation model was verified by comparing the formulas entered into Microsoft Excel with those in the regulatory document. The sensitivity analysis of the model to variations in the combination of PVC profile and reinforcing element was carried out to assess the correctness of the model's operation and its parametric stability. Results. The calculation model developed by VEKA Rus LLC and implemented in Microsoft Excel fully reproduces the algorithms presented in the regulatory document. The formulas for determining deflection due to wind load, temperature effects, and their combined effect were correctly implemented. The calculation model allows one to determine the actual deflection of the window mullion (cell E190) and compare it with the regulatory requirements (cell A191). A sensitivity analysis of deflection based on the selected combination of PVC profile and reinforcing insert showed that deflection varied from 1.868 mm to 15.039 mm. For deflections that do not meet regulatory requirements, cell Y192 reflects the noncompliance with the regulatory limits of L/300 and L/200.
