The steel structure is widely used in industrial buildings. Steel structure warehouse means that the main load-bearing components are composed of steel. Including steel columns, steel beams, steel structure foundations, steel roof trusses, and steel roofs, note that the walls of steel structures can also be maintained with brick walls. Due to the increase in steel production, many have begun to use steel structure warehouses, which can be divided into light and heavy steel structure workshops. Industrial and civil buildings constructed with steel are called steel structures.
The advantages of steel warehouse construction are as follows:
1. Wide range of uses, suitable for factories, warehouses, office buildings, gymnasiums, hangars, etc. It is not only suitable for single-story long-span buildings, but also for the construction of multi-story or high-rise buildings.
2. The building is simple and the construction period is short. All components are prefabricated in the factory, and the site only needs to be assembled easily, which greatly shortens the construction period. A building of 6,000 square meters can be basically installed in just 40 days.
3. Durable and easy to maintain, steel structure buildings can resist harsh weather and only need simple maintenance.
4. Beautiful and practical, the lines of the steel structure building are simple and smooth, with a modern sense. Colored wall panels are available in a variety of colours, and other materials are also available for the walls, allowing for greater flexibility.5. The construction cost is reasonable, the steel structure building is light in weight, reduces the basic cost, the construction speed is fast, and it can be completed and put into production as soon as possible, and the comprehensive economic benefit is much better than that of the concrete structure building.
Disadvantages of steel structure workshop construction:
First, the foundation of the steel structure workshop is easy to instability
Because the characteristics of the steel structure itself will be overall instability or local instability, which is related to the whole process of the foundation and the bolt, and the two are also interrelated, most of the steel structure plant instability is caused by steel, once the compression part or the flexion part of the slenderness ratio exceeds the standard value, it will lose stability. There are more objective factors leading to instability than efficiencies, such as load change, initial defects of steel, and different support conditions that will lead to instability. Foundation problems can be divided into three types: foundation strength, foundation deformation, and foundation destruction.
1. The strength of the foundation is generally manifested in the insufficient bearing capacity of the foundation and the instability of the foundation or slope.
2. The problem of foundation deformation is concentrated in soft soil, wet loess, expansive soil and seasonally frozen soil, etc. In these areas, excessive deformation and uneven settlement of foundation occur due to loading.
3. There are three forms of foundation failure: local shear failure, overall shear failure, and punching failure.
Two, steel structure warehouse steel roof damage
1. The vast majority of steel roof-bearing members are composed of thin-walled C-shaped steel and slender rods. The section shape is complex, and the node stress is concentrated and there is eccentric gravity.
2. when the steel roof design, diagram calculation load, and calculation is correct, almost close to the calculation of limit state, the bearing capacity of the structure safety reserve minimum, sensitivity to humidity, corrosion, and overload is extremely high, is easy to cause the failure accident factors, if they appeared in the process of manufacture, installation and use of various negative effects added, Steel structure roof is the most serious part of steel structure workshop.
3. The main damage is rod bending, roof collapse, node plate bending or cracking, frame rod fracture, roof deflection beyond the standard roof support buckling, water leakage, etc.
Three, steel corrosion of steel structure workshop
Steel structure warehouse exposed to the outside, the corrosion resistance of ordinary steel is not strong, especially in the external environment with large humidity and corrosive media, steel structure is easy to rust corrosion, greatly weakening the bearing capacity of components. A large number of statistics show that the collapse of steel roof truss caused by corrosion and lack of maintenance accounts for a large proportion of the total.
