Precautions for high-rise steel structure construction

Precautions for high-rise steel structure construction
Issue Time:2020-01-13
In the field of construction, the steel structure system has the comprehensive advantages of light weight, fast and convenient installation, short construction cycle, good seismic performance, fast investment recovery, and less environmental pollution. It has a "high, large, light" ratio compared with reinforced concrete structures. Unique advantages in three areas of development. A very large project for the construction of steel structures must be prepared in advance. The following will introduce the precautions for the construction of high-rise steel structures in detail.

(1) The principle of steel selection: not only can the structure be safe and reliable and meet the requirements for use, but also it can save steel and reduce the cost to the greatest extent possible. Different use conditions should have different quality requirements. As far as the mechanical properties of steel are concerned, various indicators such as yield point, tensile strength, elongation, cold bending performance, and impact toughness are indicators for measuring the quality of steel from various aspects. When designing steel structures, According to the characteristics of the structure, suitable steel is selected. The choice of steel is not only an economic issue, but also related to the safety and service life of the structure. The type of steel should be selected in consideration of the type of structure. Due to the different conditions of use, the location of the structure, etc., the steel grade should be selected differently according to different situations.
(2) The nature of the load: According to the nature of the load, the structure can be divided into two types: static load and dynamic load. Therefore, different grades should be selected for different load properties.
(3) Connection method: Different connection methods have different requirements for steel quality.
(4) When the bearing structure is exposed and exposed to low temperature, the steel should also consider the requirements of corrosion resistance and avoiding cold brittleness at low temperature.
(5) The concrete designations, steel bars and design strengths of light steel aggregate concrete materials used in the combined floor slabs and composite members of steel structures of high-rise buildings shall comply with the requirements of the current national regulations.
