Steel - structured buildings are fully constructed using steel.
They primarily consist of components like steel beams, columns, and
trusses, which are fabricated from section steel and steel plates.
These components are joined together through welding, bolting, and
riveting. In comparison with traditional buildings, they are
characterized by their light weight and simple structure, and thus
are extensively applied in numerous fields.Features and
Applications of Different Types of Steel Building Structures
Portal Frame Structure
Features: The load - bearing mechanism is straightforward, the load
- transmission path is clear, and the construction process is
rapid.
Applications: It is widely utilized in both industrial and civil
construction projects. Examples include industrial factories,
commercial facilities, and cultural and entertainment public
venues. For example, some small - to - medium - sized factories and
community activity centers often employ the portal frame structure.
Frame Structure
Features: It offers flexibility and can create relatively large
interior spaces.
Applications: It is well - suited for multi - story and high - rise
buildings, such as commercial office buildings, shopping malls, and
conference centers. For instance, many urban office towers and
large - scale shopping complexes are commonly built with steel
frame structures.
Truss Structure
Features: It utilizes tubes with small cross - sections to form
components with larger cross - sections.
Applications: It is frequently used in industrial and civil
buildings with large spans or great heights, such as large - span
roofs, bridges, towers, and offshore oil production platforms. Well
- known examples are the roofs of some large stadiums and long -
span suspension bridges.Grid Structure
Features: It is a high - order statically indeterminate space
structure formed by numerous rods arranged according to specific
rules. It features low space stress, light weight, high rigidity,
and excellent seismic performance.Applications: It can be mployed in gymnasiums, exhibition halls, gas stations, and hangars.
For example, the roofs of many large - scale gymnasiums and
exhibition centers typically adopt grid structures.
