Q:Is the floor of the steel structure slab cast-in-place or steel?
Steel structure is mainly made of steel material, and it is one of the main types of building structure.
Q:How are the steel structures single, multi story and tall, super high-rise?
High rise: a building of 10 storeys or more with a height of less than 100 meters.
Q:What does LL represent in steel structures?
Common steel girders may be floor beams or other common beamsIn terms of frame beams
Q:How long is the expected corrosion resistance of the general steel structure paint? Is there a relevant specification?
As ordinary steel structure anticorrosion coating, the composite coating iron red epoxy primer / epoxy micaceous iron oxide intermediate paint / chlorinated rubber finish form, life expectancy is 10 years.
Q:In steel engineering, what is called rigid connection? What is articulated? What kind of nodes or structural parts are applicable to the two?
Steel structure, beam to column connections are usually used in 3 forms, flexible connection (also known as articulated) and semi rigid connection and rigid connection. In engineering practice, how to distinguish a node belonging to the rigid and semi rigid or hinged connection depends on the rotational stiffness, rigid connection should not have obvious connection with the angle of angle deformation, reduce deformation of the structural resistance should not exceed 5%.
Q:Who knows what HW, HN and HM mean in steel structures?
TM, TN, TW also refers to the middle flange, narrow flange, wide flange, T steel, in which the width of the wing refers to the flange width, B= section height H, mid wing refers to B= (1/2~2/3) H, narrow wing refers to B=1/3~1/2H
Q:What is an assembled steel structure?
Modular construction is the construction of the main components and parts in the factory to complete, and then transported to the scene, after the mechanical installation, to meet the requirements of the scheduled function of the building.
Q:Where are welded parts of steel structures to be subjected to nondestructive testing?
The appearance of the weld is smooth and beautiful, and there shall be no welding defects, such as blowhole, undercut, flowing, welding failure, incomplete sealing angle and non sealing.
Q:What is the fire-resistant time of steel column under steel structure?
The steel structure is generally 450 to 650 degrees Celsius in temperature will lose the bearing capacity, big deformation, resulting in steel column and beam bending, the results caused by excessive deformation can't continue to use, generally without steel structure fireproof limit protection for 15 minutes. The length of time is also related to the speed of heat absorption of the component.
Q:Steel structure workshop column and top beam how to use materials?
The column load is larger, and relatively high age, should choose the lattice column in materials under the same lattice column can increase the section moment of inertia and radius of gyration, improve the stiffness and stability of pillars.
