In the construction field,
the steel structure system
has comprehensive advantages such as light weight, fast and convenient
installation, short construction period, good seismic performance, fast investment recovery, and low environmental pollution. Unique advantage
s in all aspects. Steel structure construction is a very large project, and some preparations must be made in advance. The following will introduce the precautions of high-rise steel structure construction
(1) The principle of steel selection: not only can the structure be safe and reliable and to meet the requirements of use, but also the greatest possible saving of steel and lower cost. Different conditions of use should have different quality requirements. As far as the mechanical properties of steel are concerned, the yield point, tensile strength, elongation, cold bending performance, impact toughness and other indicators are all indicators to measure the quality of steel from various aspects. According to the characteristics of the structure, select the appropriate steel. Whether the choice of steel is appropriate is not only an economic issue, but also related to the safety and service life of the structure. When selecting steel, the type of structure should be considered. 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, if the load properties are different, different grades should be used.
(3) Connection method: Different connection methods have different requirements on steel quality.
(4) When the load-bearing structure is exposed and in a low-temperature environment, its steel should also consider the requirements of corrosion resistance and avoiding cold and brittle at low temperatures.
(5) The concrete designation, reinforcement and design strength of the composite floor and composite members of the steel structure of high-rise buildings, as well as the lightweight aggregate concrete materials, etc., shall meet the requirements of the current national regulations.
