Abstract

The paper identifies the key issues concerning design and calculation of energy efficient windows of high-rise buildings that should be considered at the initial stages of a building design. The analysis of the functional and technical requirements which must be met by window structures in high-rise buildings was performed. The features of wind loads on the high-rise building windows were considered. The specificity of providing air- and water permeability of high-rise building windows under the action of high wind loads was considered. The conducted scientific research review on specific design and calculation issues of high-rise building windows was made. It is established that they are mainly aimed at finding optimal design solutions of the high-rise building windows in terms of energy efficiency. A similar situation is observed in the design of windows, when the issues of ensuring the strength and reliability of these structures are given less attention. It is established that at present, the strength calculation methods of fasteners and protective fences of windows are not developed; the excess stock is laid in the method of profile elements strength calculation, which is confirmed by the results of laboratory tests. The prospective scheme for calculating and appointing design solutions of high-rise buildings windows was presented, which provides an opportunity to ensure reliability, durability, and operational safety of high-rise building windows during all their life cycle. The paper specifies areas for further research of the matter under consideration.

Highlights

Over the past few years, the volume of construction of high-rise buildings and complexes in Russia and the world has increased significantly
A distinctive feature of such structures is the predominant use of glazed large-format window units, rather than translucent facades characteristic of high-rise public buildings
This is due to both modern architectural tendencies and, often, lower cost of manufacturing, installation and operation of window units in comparison with translucent facades

Summary

Introduction

Over the past few years, the volume of construction of high-rise buildings and complexes in Russia and the world has increased significantly. A distinctive feature of such structures is the predominant use of glazed large-format window units (see figure 1), rather than translucent facades characteristic of high-rise public buildings (first of all, administrative and office centers). This is due to both modern architectural tendencies and, often, lower cost of manufacturing, installation and operation of window units in comparison with translucent facades. The high-rise building window design and calculation is much more complicated than similar structures used in multi-storey buildings with a height of less than 75 m. The purpose of this work is the review of the design problems of high-rise building windows, taking into account their loads and actions
