Analysis Of Structural System And Joint Selectiveness In High-rise Steel Residence And Its Apply

As everyone knows, the section dimension of structural member is dominated by lateral applied force (wind and earthquake are essential) in high-rise building, so selecting an appropriate structural system is very important in high-rise steel residence. It not only affects function of the whole construction and realizement of structural employment, but also affects cost of the project. In our country, high-rise steel residence has some frequently used structural system, such as (1) the steel frame system. (2) the brace-steel frame system. (3) the shear wall-steel frame system.The joint of structural member is hinge for guaranteeing safety of high-rise steel residence, and affects the function of load very much. The joint's design is very important in the design of building. Whether or not the joint' s design is appropriate, it not only influences quality of manufacture and install, but also affects the period of construction and the cost of building. Consequently, the joint' s design must be taken seriously in the design process.This paper presents a structural design of a 18-story high-rise steel residence, from the conceptual design to the detailed design. The design start from analyzing structural system for this building, and the appropriate structural system is investigated. The shear wall-steel frame system is selected, with concentrically braced frames in both sides. The design satisfies the story drift requirement prescribed in the code, and it is secure, reliable, economical, etc. This paper can be referenced to design high-rise steel residence.
