Complicated Steel Structere
Light steel structures are not strictly defined and can be distinguished by the cross section of the main structural members. Therefore, the following structure can be called a Light Steel Structure : (1) a structure made of cold-formed thin-walled steel;
(2) a structure made of hot-rolled lightweight steel; (3) a structure consisting of welded and high frequency welded lightweight steel;
(4) a structure made of round tubes, square tubes, rectangular tubes, etc.;
(5) a structure made of welded steel plates;
(6) a structure made up of various components.
1, workshop crane lifting weight: greater than or equal to 25 tons, can be considered for steel structure. 2 per square meter, the amount of steel: greater than or equal to 50KG/M2, is considered to be a steel structure. 3, the main component plate thickness: greater than or equal to 10MM, light steel structure with less. In addition, there are some reference values, such as the cost per square meter and the weight of the largest component
Light steel structure design code (Shanghai standard) is to distinguish between light steel and general steel; light steel structure housing is not strictly defined, usually can be used to distinguish the main force components of the cross section. Therefore, the following structure can be called the light steel structure: (1) structure made of cold-formed steel; (2) made of hot-rolled steel structure light; (3) the welding structure of the light type steel by welding and high frequency; (4) the structure of round tube, square tube, rectangular tube etc. made; (5) structural components made of thin steel plate welded made; (6) the structure made of all component composition. Determination of the structure of steel and steel structure does not have a unified standard, many experienced designers or project managers are often not completely clear, but we can take some data into account and judge: 1, workshop crane lifting weight: greater than or equal to 25 tons, can be considered for steel structure. 2 per square meter, the amount of steel: greater than or equal to 50KG/M2, is considered to be a steel structure. 3, the main component plate thickness: greater than or equal to 10MM, light steel structure with less. In addition, there are some reference values, such as the cost per square meter and the weight of the largest component
