Floor System

There is a high-rise building whose main structure is framework - core tube. In order to meet the requirements for architectural features, the distance between the outer frame and the exterior wall of core tube is relatively small, therefore the floor structure program adopts a thick plate and wide flat beam floor system, and part floors of the upper structure adopt a thick plate and dark beam system. As wide flat beams (dark beams) have a small height and cannot form effective support for the floor, special analysis has been made on floors from the security point of view without considering the role of wide flat beams (dark beams). The floor system of this high-rise building has been analyzed and discussed with regard to bearing capacity, deformation, comfort and other aspects.

The number of high-rise buildings has greatly increased in Korea, and storey height is a significant component of tall residential buildings due to the limited city area. To reduce storey height, the wide beam has been adopted in some projects in Seoul such as Trump World, Galleria Palace, and Richencia. The joints between the wide beam and the core wall were too narrow to place the reinforcement, however. This paper investigates a newly developed structural system called the innovative, technical, economical, and convenient hybrid system (iTECH system). The iTECH system has an asymmetric steel assembly with web openings, where the top plate is welded on top of inverted structural "tees" whose cut is referred to as a "honeycomb" type. Both sides of the web and the slab are filled with cast-in-place concrete. The shear capacity was experimentally evaluated and verified, with parameters determined by factors that shared the shear strength of the iTECH beam. The steel web, inner concrete panel, and outer concrete panel contributed to the shear strength of the iTECH beam. The shear stirrup did not contribute much to the shear strength, however, and therefore a design equation using the steel web and inner concrete panel was suggested.Key words: composite beam, shear capacity, monotonic test, high-rise building.

<p>With the speeding up of urbanization and increasing of urban population, the urban land resources are increasingly scarce. Emergence of ultra high-rise building is an inevitable trend. At present, our construction industry is in the rapid development period, where the proportion of ultra high-rise buildings in urban architecture of many big cities constantly increases. The improving ultra high-rise engineering technology is an important part of the construction industry in our country. This paper will analyze the ultra high-rise construction technology of building work in detail.</p>

Concrete-encased CFST (concrete-filled steel tube) is a kind of composite structure comprised of a CFST component and a reinforced concrete (RC) component. The concrete encased CFST possesses superior ductility and higher stiffness. They are gaining popularity in high-rise buildings, large-span structures, bridges, subway stations and workshops. This paper initially reviews the recent research on concrete-encased CFST structures. The major research findings on bond performance, static performance, dynamic performance and fire resistance are presented. This paper also outlines some construction considerations, such as the utilization of materials, the fabrication of the steel tube, and the methods of casting the inner and outer concrete. Finally, some typical practical projects utilizing concrete-encased CFST members are presented and reviewed.

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.
