In engineering design, there is often a demand for large space, and steel joist is often used to meet this demand. In the design of planar steel joist roof, the design and arrangement of bracing system is the most important, which is directly related to the stability of the roof.
In conclusion, when choosing fireproof coating, it is necessary to consider the actual situation of the plant, fire prevention requirements, coating performance and economy and other factors.
Although steel structure material is widely used in construction projects, it also has certain defects and needs to be appraised for its safety in order to ensure the safety of people's lives and properties.
When choosing fireproof coatings, in addition to considering the thickness of the coating, it is also necessary to make comprehensive considerations based on the actual situation of the steel structure, fire resistance requirements, decorative effect, and economy and other factors.
both space frame structures and reinforced concrete structures have their own advantages and limitations in terms of earthquake resistance. The specific choice of which structural form needs to be considered comprehensively according to engineering requirements, geological conditions, environmental factors, and economic and technical feasibility.
Load analysis is a crucial step when designing steel structures.
flexible nodes allow a certain degree of relative displacement and rotation of the rods, this node is usually realized through the structure of the ball or bearing, can reduce the stress concentration at the node, increase the overall flexibility of the structure.
Thin, thick and ultra-thin fireproof coatings are categorized according to coating thickness and fire resistance limit.
The design of steel buildings should be as regular as possible, avoiding complex structural forms.
steel structure has the advantages of uniform material and high strength, good plasticity and toughness, fast construction speed, energy saving and environmental protection as well as high space utilization rate in construction projects, which make steel structure widely used in construction projects.
In steel structure engineering, the choice of connection form is directly related to the overall performance and safety of the structure. Among many connection methods, high-strength bolt connection occupies a place in the field of steel structure with its unique advantages.
Membrane structures are variable in shape and there may be more than one most unfavorable wind angle.
