Analysis of Common Steel Structures in Industrial Buildings: The Outstanding Advantages of Space Frame Structures

-

In the construction of modern industrial buildings , steel structures have become the preferred choice for an increasing number of enterprises due to their unique advantages. Not only can they meet the demands for large spans and expansive spaces, but they also excel in construction efficiency, cost-effectiveness, and sustainability. Selecting the appropriate steel structure configuration is crucial to ensuring the functionality, safety, and economic viability of the building. 1. Portal Frame Structure Characteristics: A frame structure comprising solid or lattice steel columns and beams connected rigidly. Features a straightforward design with clear load transfer pathways. Advantages: Simple structure: Relatively straightforward to design and construct, facilitating standardisation. Rapid construction: Components are highly prefabricated in factories, enabling swift on-site assembly. Cost-effectiveness: Relatively low construction costs for medium-to-small span industrial buildings (t...

Disadvantages of prestressed concrete structures

  Concrete Steel Structure 1. The process is more complex, high quality requirements, thus requiring a more skilled professional team, and there are problems of interspersed types of work. 2. Sub-stress. Secondary stresses due to prestressing, creep and shrinkage effects, temperature variations, and bearing subsidence can be severe in continuous structures unless these are controlled or accounted for in the design. In prestressed continuous structures, it is interesting to note that these secondary stresses can often be exploited advantageously, and thus the secondary stresses will increase the economy of the structure. 3. Friction losses in continuous force bars. Friction losses can be significant if there are many reverse curves, if the curves have large deflection angles, or if the force bars are too long. In beams with corrugations or added axils, friction losses can be minimised by using straighter cables. The usual methods of over-tensioning and tensioning from both ends can ...
