Abstract

Among many tasks to be done by the state, the most significant is a social-economic one i.e. provision of its citizens with affordable, long-lasting, energy- efficient and economical housing. One of the ways of doing the given task is the application of concrete-filled steel tubular (CFST) structures, for the elements of a building, of circular, square or rectangular type. It is also possible to use such structures not only for a new housing stock but in the reconstruction of present one at the expense of additional storeys (about 20); without demolition and total resettlement of tenants of the house under reconstruction. Alongside with this, there is an opportunity to increase total area of residential houses and make new types of comfortable place of various purpose.

Highlights

At present buildings from monolithic reinforced concrete in shallow and large-panel formwork are erected using large-block and frame construction technology
Expansion of monolithic-framing house construction causes considerable capital investments connected with frameworks, depends on weather conditions, it is characterized by big material consumption and construction cost and terms
In foreign construction practice the most widely used are not bearing monolithic building envelopes or reinforced concrete columns but as well as combined frame-core system with a bearing core made of monolithic reinforced concrete and external frame made as a bearing shape of columns peripherally located to a building, which is rationally combined with horizontal outrigger-foundation frame work located in every 15-25 storeys [1,2,3,4]

Summary

Introduction

At present buildings from monolithic reinforced concrete in shallow and large-panel formwork are erected using large-block and frame construction technology. In Australia the first residential building (46 storeys) was built in 1990 in Melbourne. The core of the building was formed with steel concrete shafts. 24 CFST columns were located peripherally the building. In Japan 57storey building was built with the use of concrete-filled steel tubes. The base of the building is a CFST framing. Concrete-filled steel tubes are widely used in China in the last decades. A large number of skyscrapers were built in China using CFST frames
