Abstract
In the following article we examine problems faced when designing PVC windows for high-rise buildings, which are usually not considered when constructing objects for massive sites, using a high-rise residential complex as an example. We address the matters related to wind loads on windows & statistical calculation of the impact of wind loads on them. We have presented variants of installing load-bearing elements of PVC windows which accept wind loads. We conducted a laboratory experiment by simulating wind loads on the window design, which is actually used for glazing the examined high-rise building. In the course of the experiment we determined additional factors which need to be considered when constructing PVC window structures for glazing high-rise buildings. We can determine that the following calculation method for the impact of wind load on PVC windows gives higher values of the desired statistical characteristics of load-bearing elements of a window compared to the results of laboratory experiments. We provide prerequisites to improve the analytical method of calculating impact of wind loads on load-bearing elements of PVC windows.
Highlights
The construction volume of high-rise buildings in the world is constantly increasing, especially in the residential sector [1,2,3,4,5]
The use of PVC windows in high-rise buildings, which are subjected to high values of wind loads during construction & operation, needs consideration as to the technological construction features of the PVC window system, as well as the structural concept, parameters & the construction technology of the building
The existing rules for the statistical calculation of PVC window units is based on the assumption that operational loads occurs only by steel liners installed inside profile elements made of PVC
Summary
The construction volume of high-rise buildings in the world is constantly increasing, especially in the residential sector [1,2,3,4,5]. To reduce the cost of construction of high-rise buildings, we introduce technologies which were previously used only in mass construction sites. One such example is using PVC windows when glazing high-rise buildings instead of using traditional aluminium windows. In the article we examine the questions of designing & statistical calculation of PVC windows using a high-rise apartment building which is 140m in height as an example. For glazing the building we use large-size structures of window units from the PVC profile. The designed window unit with load area of maximum collection of wind loads is presented in figure 1
