Q:What is the ultimate capacity of steel structures?
I. The ultimate bearing capacity of steel structure means failure due to fatigue.Two 、 the ultimate limit of bearing capacity is the state that has been destroyed and can not be used. The serviceability limit state is also barely usedThree, the structure or component to the maximum carrying capacity, or reach the limit state of deformation which is not suitable for continued load.
Q:What is the steel structure of portal frame and frame difference
The bent frame is the two row of columns, the roof trusses above, and a board placed between the roof trusses of the two rows of columns, forming a continuous structure.
Q:Why should we add air holes to the embedded parts of the steel structure?
The embedded parts is provided with a ventilating has two uses: one is that it can be used to insert concrete vibrator vibration rod.
Q:Why can't epoxy paint be used in outdoor steel structures?
Epoxy paint has the advantages of good adhesion, tough film, corrosion resistance, rust resistance and moisture resistance. It is widely used as antirust primer for steel structure and antirust coating for interior steel structure.However, epoxy paint should not be used as topcoat for outdoor applications, that is, epoxy paint can not be irradiated by sunlight for a long time.
Q:Definition of large steel structures
As a green environmental protection product, steel structure has the advantages of light weight, high strength and good seismic performance compared with the traditional concrete structure. The structure is suitable for the small proportion of the total load of the live load, and is more suitable for the construction of large span space structures and high-rise structures, and is suitable for construction on soft soil foundations. It also conforms to the national policy of environmental protection and conservation and intensive utilization of resources, and its comprehensive economic benefits are increasingly recognized by all investors, which will objectively urge designers and developers to choose the steel structure.
Q:Steel plate for steel structure, what kind of steel plate is it
To make a steel plate, such a phrase, I think, is a little worse.This word is a relatively large range, according to that there is no special requirements, can use general steel: carbon steel structure can be, such as Q235, Q345, Q235 belong to ordinary carbon steel structure, Q345 is the last name 16Mn, belongs to low alloy series.But if it's special, it can be bridge, steel plate, Q235q, etc.. Q345q and so on.
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 rib of steel structure?
Is in the beam web on both sides of configuration, perpendicular and beam flange and web (most so, some web and not vertical) two plates, there are unilateral configurations, but rarely, at the ends of the beam can be used in a sealed.
Q:What is the brittle fracture of steel or steel structure?
Brittle fracture of steel or steel structure means a sudden fracture under the nominal stress (tensile strength or yield strength of steel under tensile test). The fracture surface is usually a single and relatively flat, split surface with little or no shear lip.
Q:How much is the square metre of steel structure engineering cost now?
If only the frame, comprehensive cost at about 1500-1800 yuan / square meters, is a basic frame and a partition, an area of 100 square meters, two floors cost about 300 thousand yuan, and now the cost general steel frame structure cost is relatively close, with the to further optimize the industrial degree and the improvement of building materials, is expected to cost can also be reduced continuously.
