Q:What does the title of a steel structure mean?
A truss is a structure in which the bars are hinged with each other at both ends. The straight rod truss has a generally triangular unit plane or space truss structure, mainly bear axial tension or stress, which can make full use of the strength of materials, the span is large than the solid web beam to save materials, reduce the weight and increase the stiffness. In the membrane structure building, truss design is very important, or it can support the whole building.
Q:What are the methods of steel structure rust removal, which method is good?
Three kinds of rust removal methods are different, the first two kinds of rust thoroughly, the third methods used for small area, no rust removal equipment; fourth methods are used only, that is, there is no equipment, and the requirements are not high.
Q:What are the differences between steel structure design and reinforced concrete structure design?
When the ratio of the free length L1 of the compression flange to the width B1 of the cross section tubular support beam does not exceed the specified value.Structural measures shall be taken to prevent torsion at the end of the beam.For beams without lateral support points in the midspan, L1 is the span; for the beams with lateral supporting points in the midspan, L1 is the distance between the lateral supporting points of the compression flange (the lateral support of the beam is considered as lateral support).
Q:What is steel structure steel plate?
The penetration welding spot welding, welding should be prepared before the arc welding test pieces, adjust the welding current. Because the floor plate at the bottom of horizontal and vertical supporting formwork, pouring concrete material should not be too concentrated, the plate vibrator timely allocation of vibration.
Q:What does "HJ-1" mean in steel structures?
In steel structure, HJ-1 is truss number 1.
Q:How to consider the influence of base displacement on steel structure
When performing the structural search and acceptance, the steel structure is completed after installation. Often issued axis displacement, the vertical deviation is too large and the height of the column column below the design elevation. In the high-rise steel structure engineering, it is also found that the spacing of each column is too large or too small, and it is often found that the top elevation at both ends of the beam is inconsistent when searching the top of each layer.
Q:What does "fixation" mean in steel structures?
It is one of the connecting patterns between two components.
Q:What kind of building materials are used in steel structure engineering?
Secondary frame, shear key (column bottom), purlin (walls, roof), daughter column (the wall) and canopy (wall), gutter (walls, roof), steel tile (walls, roof and so on).
Q:Ratio of width to thickness in steel structure design,
Masonry column and wall mixed structure in a house, in addition to meet the capacity requirements, must also have sufficient stability, masonry column and wall height ratio calculation is to ensure the stability of important structural measures, to prevent the loss of masonry column and wall stability in construction and use process.The ratio of height to thickness refers to the calculated height of masonry column and wall and the thickness of the wall or column section length H. The ratio of height to thickness of masonry walls and columns is bigger, indicating components more slender, its stability is worse. Masonry column and wall thickness ratio calculation is to restrict the length of the component from the the structural dimensions of components, to ensure its stability.
Q:What is the life span of steel structure?
The life of steel is infinite (without corrosion). There are many factors affecting the life of steel structures, in which the reference period of live load is 50 years. So the design cycle is 50 years. The most important special projects in the country can be listed for 100 years.
