Abstract

The intensive expansion of high-rise construction is observed in Russia during the last several decades. Today it is hard to imagine a Russian metropolitan city without a skyscraper, whether it is a multipurpose business-center or a residential building. High-rise buildings in Ekaterinburg (which is a center of Urals) include not only office buildings, but also residential buildings higher than 100 meters. It is worth mentioning that most of these high-rise buildings were designed by local design companies without the participation of foreign specialists. The reliability and strength of the building structures received the particular attention during the high-rise building design process irrespectively of the function of a building. It is well known that the reliability of building structures shall be assured as early as the design stage, and therefore it is necessary to pay a special attention to the analysis of bearing structures under worst-case combinations of design loads in order to prevent them from influencing the strength of the building structures in the course of its service. Also it is important to note that high-rise buildings are subject to factors extrinsic to low-rises, such as aerodynamic loads. In addition to the wind loads, aerodynamic conditions of the building location in general also have a significant effect. In this work the authors review the specifics of design of high-rise building in Urals region on the example of one of the high-rise residential complexes in Ekaterinburg. Basic design conditions are described and architectural, planning, and design features of the building are reviewed. Effects of harmful factors acting on the building frame, including the wind loads, are analyzed. Some distinctive features of the analysis of the bearing structures are given. The conclusion contains the summary on specifics of high-rise buildings design and construction in Urals.

Highlights

The intensive expansion of high-rise construction is observed in the whole world
It was found that the buildings surrounding the new complex were not taken into account in the calculation of wind loads that was performed at the design stage
Due to the limited experience of designing high-rise buildings and insufficient Russian regulatory base, it may be hard for local designers to evaluate wind effects correctly

Summary

Introduction

The intensive expansion of high-rise construction is observed in the whole world Such expansion can be attributed to the reduction of areas allocated for the construction of new buildings. First modern high-rise residential buildings in Ekaterinburg were built in the beginning of the 21st century [1, 2]. It was the complex of residential buildings named Aquamarine, the maximum height of the buildings of this complex was 93 meters. There are more than 20 high-rise buildings with height varying from 75 meters and above in Ekaterinburg.
