Development trend of anti-seismic technology of steel structure
As the construction of steel structure warehouses and steel structure workshops continues to increase, the earthquake prevention technology of steel structure workshops and steel structure warehouses has also received increasing attention. The steel structure finds the characteristics of the earthquake damage between the steel structures, which helps the steel structure to better prevent earthquakes, find the characteristics of the damage of the steel structure, and then prevent it, you can reduce the casualties of people in the event of a major natural disaster. To reduce building damage.
The general situation of the destruction of steel structure workshops and steel structure warehouses is not due to the insufficient strength of the rods and often caused by the instability of the rods. Therefore, the reasonable arrangement of the support system and the overall stability of the plant structure are particularly important for the steel structure workshops and steel structure warehouses. In terms of the overall layout, it is required that the quality and rigidity of the factory building and warehouse structure are evenly distributed, so that the factory building and grain storehouse are under uniform stress and coordinated deformation, and try to avoid the adverse impact caused by the uneven structural rigidity against earthquake.
The center support frame of seismic fortification should adopt a cross-crossing diagonal rod, single diagonal rod herringbone diagonal rod or V-shaped diagonal rod system, and K-shaped diagonal rod system is not allowed. When using a single inclined rod system that can only be tensioned, two sets of single inclined rods in different tilt directions should be set at the same time, and the difference in the projected area of the horizontal section of the single inclined rod in different directions in each layer should not be greater than 10%.
Judging from the market trends in recent years, the raw materials of steel structures are of a rising curve type. From the overall development trend, this annual bullish situation will not change for a while. And this year, under the situation of soaring materials and rising wages of employees, the price of steel structure raw materials has increased more than in previous years. When the raw materials of Qingdao Yili Steel Structure will definitely rise, the market response is rapid, and capable steel structure enterprises decisively start to hoard raw materials, such as various types of steel, color steel plates and so on. Many steel structure companies are aware that the current stock of steel in China is not a lot, but the wind of price increases is spreading. Many companies have also joined the ranks of hoarding raw materials and pushing up prices because of the burden on the future.
