How to reduce the amount of steel in steel structure?

The  modern steel structure  platform has various forms and functions. Small but complete. The biggest feature of its structure is the fully assembled structure, which is flexible in design. It can be designed and manufactured according to the actual situation of different sites, which meets the requirements of the site, the development of useful functions, and the requirements of logistics technology. Widely used in  modern storage . Composition and classification of the platform structure 1. Composition: usually platform structure, usually supported by a platform structure is composed of primary and secondary beams, columns, and ladder primary and secondary beams, columns, support columns, and ladders, railings between the poles, etc. Components. 2. Classification: According to different technical requirements, it can be divided into indoor and indoor platforms, static and dynamic load platforms, production auxiliary platforms, and medium and heavy operating systems. Ac...

1. The standard value of the permanent load of the   steel structure   canopy is 0.8kN/㎡ (excluding the weight of the stressed member), and the standard value of the additional permanent load of the canopy is 0.3kN/㎡ when calculating the wind suction. 2. The standard value of the live load of steel frame canopy is 0.5kN/㎡.     3. Snow load of metal building canopy: the basic snow pressure is 0.4kN/㎡, 0.7kN/㎡ (standard value of snow load: Sk=μtSo,μt=2). In areas where extremely heavy snow loads may occur, the designer should Select after review.     4. Wind load: basic wind pressure: 0.55kN/㎡, 0.75kN/㎡; the standard value of wind load is calculated according to the enclosure structure. In areas where extreme wind loads are likely to occur, it should be selected by the designer after review. Standard values ​​of wind load: wk=βgzμsμzWo, βgz=1.0, μs (negative wind)=-2.0, μs (positive wind)=1.0, μz=1.14. 5. The standard value of several loads for constructio...

The calculation formula for  steel structure  stairs is 2h b = 600 plus or minus 20. This formula is based on ergonomic principles. Usually in adults, the step length is about 750. Through the influence of the height on the stairs, the step length becomes shorter and the height becomes higher. Higher, shorter step length. Therefore, the height influence factor can be multiplied by 2. Generally there are the following sizes: 300X150, 280X160, 260X170, 250X175, etc. The step height of the public stairs is 160-170mm. The ordinary cement base of the stairs in the house is at such a standard, and 160mm is a more comfortable height. The calculation rules for steel structure stairs of  steel structure building  are as follows: 1. The horizontal projection area of ​​the stairs: the cast-in-place concrete stairs are calculated based on the horizontal projection area according to the design diagram size. The stairwell with a width less than 500mm is not deducted, and the part ...

Should the foundation of a  multi-story steel structure factory  be built? This is a very professional question, and only the editor can help you find a professional answer. For the foundation of the same structural unit, part of the natural foundation and part of the artificial foundation should not be adopted. It is also not advisable to adopt two or more types of soil layers with large differences in properties as the supporting layer. When the end approaches or partially enters the inclined top surface of the underlying soil layer, it is advisable to deepen the foundation or increase the pile length so that the bottom of the foundation of the pile ends are all in the same underlying house to avoid possible uneven settlement. The  steel structure building  site cannot avoid the marginal sections of rivers, lakes, and old rivers that may cause slippage or ground cracks during earthquakes, and targeted foundation stabilization measures should be taken and the founda...

What problems should be paid attention to during gas cutting and demolition of  steel structural components ? A.  Process points that should be paid attention to during gas cutting of  steel structure components : 1. Before gas cutting, it is necessary to introspect to confirm that all the equipment and tools of the gas cutting system are operating normally and to ensure safety; 2. Before gas cutting, remove the dirt, oil, rust and other sundries on the surface of the steel, and leave a certain space on it to facilitate the blowing of slag; 3. When cutting, the shape of the oxygen jet should be adjusted to make it reach and maintain the clearness of the round, long wind line and high shooting power; 4. When gas cutting, tempering must be avoided; 5. In order to avoid gas cutting deformation, the operation should be stopped from the short side; the small pieces are cut first, and the big pieces are cut later; the complicated ones are cut first, and the complicated ones lat...

General cranes are widely used in indoor and outdoor  steel warehouses ,  steel workshops , docks, and open storage yards. The crane is mainly composed of cart operating mechanism, trolley operating mechanism, hoisting mechanism, and electrical equipment. The two ends of the frame are supported on the elevated track above the workshop or open-air cargo yard through the running device and run longitudinally along the track. And the crane trolley runs horizontally along the trolley track on the main beam frame. Technology engineers need to take features of the crane beam into consideration during the steel structure designing. Crane Beam Design Generally, crane beams are simply supported (simple structure, convenient construction, insensitive to support settlement) with common forms of  steel beams (1), combined I-beams(2), box beams(3), crane truss(4), etc. Crane Beam  Load Permanent load (vertical). The dynamic load has horizontal and horizontal direct...

Do you know what are the seismic layout requirements of steel structures? In this issue,  steel structure manufacturers  will introduce to you: 1. The floor should adopt a profiled steel plate cast-in-place reinforced concrete composite floor or non-combined floor. 2. The arrangement of the supporting frames in both directions should be basically symmetrical, and the aspect ratio of the floor between the supporting frames should not be greater than 3; Steel structure seismic engineering 3. When a basement is installed in a steel structure house, the frame column should extend to at least the first floor underground; 4. When the steel structure with more than 12 floors adopts an eccentric support frame, the top layer can adopt central support; 5. For the steel frame-tube structure with more than 12 stories, if necessary, a reinforcement layer composed of outriggers or outriggers outside the tube and surrounding frame can be provided; We all know tha...
