ENGINEERING METHOD FOR CALCULATING TEMPERATURE DEFORMATIONS OF PVC WINDOW PROFILES WITH A REINFORCING STEEL CORE

Engineering Method for Calculating Temperature Deformations of PVC Window Profiles with a Reinforcing Steel Core

In current engineering practice, static calculation of windows for temperature loads is not performed.However, the existing experience in operating PVC windows in environmental conditions of Eastern and Northern Europe shows that the temperature deformation of such structures can reach values comparable to those of wind loads, which leads to a sign
