Q:The meaning of UT in steel structure
Ultrasonic testing (ultrasonic, testing). The use of an object's own or defect's acoustic characteristics to detect the effects of ultrasonic propagation on object defects or certain physical characteristics. The ultrasonic frequency used in ultrasonic testing is between 0.5 and 5 MHz (MHz). The most commonly used ultrasonic test is pulse flaw detection
Q:What are the main structures and sub structures in the steel structure?
Main components: steel column, steel beam, crane beam and other large main componentsComponent: column bracing, horizontal support, tie bar, brace, casing etc.
Q:Is the floor of the steel structure slab cast-in-place or steel?
The steel floor of the steel structure building is steel.
Q:How are the steel structures single, multi story and tall, super high-rise?
Tall, super high-rise, mainly using steel mixed structure, such as cross column. Box shaped column and other structural forms.
Q:What does "PD140*4" and "PL12*150" mean in the steel structure drawing?
PD is a steel tube with a length of 140 and a diameter of 4.PL is a steel plate with a thickness of 12 and a width of 150.
Q:What does "pre assembled" of steel structure mean?
Structure of steel (pre-assembly)The block manufacturing of large span beam column, truss, supporting steel and steel frame structures, especially in connection with high strength bolt with large steel structure, block production and supply of steel shell structure, the whole process or separate temporary assembly operations in the factory. Pre assembly is an effective measure to control the quality and ensure the installation of components in the field.
Q:What does LL represent in steel structures?
LL means coupling beam.The coupling beam refers to the connection between the wall member and the wall member in the shear wall structure and the frame shear wall structure, and the coupling beam is the beam at both ends connected with the shear wall in the plane
Q:Large steel structure stress analysis, what software is good?
Landlord said SW, COSMOS, 3D3S, I have not used, do not comment. As for the PKPM software is the mainstream architectural design software, the rules of the structure is more applicable. The concept of a major feature of this software is "layer" is more obvious, is relatively rigid, through the "layer" bar calculation results often appear abnormal (such as crossing the floor column and brace etc.), so the industrial equipment no floor concept, to be especially careful when using. The panel you said could not be analyzed by finite element method.But PKPM also has the advantage, that is, get started quickly, for architectural design is relatively user-friendly, you just follow the prescribed steps step by step, you can basically complete modeling. In addition, he close to domestic norms, post-processing easier.Of course, some of the PKPM modules, I did not fully use, the evaluation of PKPM may not be accurate, comprehensive, please correct me downstairs.
Q:What is a light portal steel frame?
Plasticity and toughness are good. Steel has good plasticity. The steel structure will not happen sudden damage in general, but it will be marked by a larger deformation in advance. In addition, the steel has good toughness and can withstand the dynamic load well. All these provide a reliable guarantee for the safety of the application of steel structure.High degree of industrialization - steel structure is made of various kinds of materials (I-beam, channel steel, angle steel) and steel plate. Through the cutting, welding and other processes, the steel component is manufactured, and then the site is installed. The general steel structure can be used in the metal structure factory with a high degree of mechanization and specialized production. Therefore, it has high precision and short manufacturing cycle. Due to the assembly operation, the installation efficiency is high and the construction period is short.Demolition convenience - steel structure due to high strength, it is suitable for the construction of light weight, easy to connect structures can be removed.
Q:Can steel frames and channel steel be welded longer?
There is no special requirement for the splicing of steel in general steel structure, so long as the design size can be reached.Frame steel channel is a general steel structure, only requires strong welding, forming beautiful, no deformation.
