Nowadays, under the  situation  of  the accelerating  process  of urbanization,  our  social economic development has also been leaps and bounds and  the  corresponding construction industry has also been high speed developed. Our country in the field of land resources still insist on a solid  strict  management control, therefore, in this context,it will inevitably lead the land resources to face with a tense situation which has become a great test forhigh-rise residential building construction as it appears repeatedly.  Normally, high-rise residential buildings have the characteristics of limited operating surface, high investment  cost,  long construction period and high requirements of construction technology. In view of this, this paper mainly analyzes the high-rise residential building construction technology.

Selection Of

Purpose – The purpose of this paper is to present a systematic approach for the evaluation and selection of curtain wall systems for medium-high rise building construction. Design/methodology/approach – The authors have identified the different types of curtain wall systems that are commonly used in the building construction industry in Saudi Arabia; examined the various performance as well as financial and non-financial criteria affecting the evaluation and selection of these systems; and subjected the identified different types of curtain wall systems to several filtering processes, namely feasibility ranking, evaluation by comparison and weighted evaluation to facilitate making a decision on the most suitable system to select. Findings – The analysis of the collected data indicated that the precast concrete curtain wall system is considered to be the first choice. The second choice is the prefabricated brick panel curtain wall system. Originality/value – Curtain walls are the most recognized elements of contemporary structures today. There exists ample variety of materials and designs that could be utilized for the development of these building elements. This paper is of practical value to project owners, architects and design professionals endeavoring on the process of selecting and specifying curtain wall systems in their projects.

Cfst Columns

Concrete-filled steel tube (CFST) columns are increasingly used in the construction of high-rise buildings which require high strength and large working space especially at lower stories. As compared to reinforced concrete columns, existence of the exterior steel tube not only bears a portion of axial load but also most importantly provides confinement to the infill concrete.with the confinement provided by the steel tube, axial strength of the infill concrete can be largely enhanced.this paper presents the investigation effect of impact load on concrete-filled steel tube columns under fire by numerical simulations using ABAQUS software.the results indicate that the CFST sections with larger confinement factor ξ=1.23 behaved in a very ductile manner under lateral impact. And the sections with smaller confinement factor ξ=0.44  generally behaved in a brittle mechanism.

High dropping non vibration concrete is widely used in high-rise steel tube concrete construction. In this paper, a high dropping non vibration self-compacting concrete with high mobility, low slump loss, and good anti-segregation ability is developed by mixing addition of PCA superplasticizer and SCC composite expansive admixture. The test results showed that the admixture and cement used in the test possess sound compatibility. The slump flow of self-compacting concrete prepared are more than 660mm, T500 of 2.8~7.5s, 1h slump flow loss of less than 10%, and the segregation rate of less than 7.5%. Through strictly control production and dropping construction, supplemented by field ultrasonic detection measures, the high dropping self-compacting concrete in steel tube achieved successful application for a high-rise building.

Steel-concrete composite structures are widely used in large-span spatial structures, high-rise building, super high-rise building and bridges and so on thanks to its advantages in terms of mechanical and construction properties. And the corresponding design codes on circular, square and polygonal concrete filled steel tube (CFST) have been formed at home and abroad. However, application of round-ended CFST is still very rare in the world and there is no corresponding theoretical research findings and design basis. There is an actual project that a round-ended CFST coupled tower column is applied in Houhu Bridge in Huangpi area, Wuhan city. Real-time stresses of the coupled tower column were monitored throughout construction phase to ensure that the force and linearity of Houhu Bridge can meet its design requirements. In the paper, the real-time stress monitoring data is analyzed so as to find force state and force characteristics of this new structure of round-ended CFST during construction phase. This study provides basic information for further formation of round-ended CFST design theory in future which plays an important role in engineering application of the round-ended CFST.
