<input id="uauy4"></input> Steel is currently included in the "Thirteen Five" construction planning, steel compared to other materials, has a big advantage, the steel structure is flawed.
Guangzhou Steel is manufactured by the factory and on site installation, processing stage, have an impact on the performance of steel, resulting in steel initial geometry defect that is defective. In the mechanical analysis, we idealize the structures and members, but in the actual project, this will result in geometric imperfections. Column mounting deviation caused by steel construction and acceptance of Guangzhou Steel factory. Currently geometry defect is effective to improve the accuracy of the construction.
Guangzhou Steel isotropic and homogeneous properties will result in mechanical defects, have a great impact on the steel structure. Steel limit state divided into the ultimate limit state and limit state. Ultimate limit state generally corresponds to the structural member or not suited to continue to carry the resulting write or appear drunk carrying capacity, including loss of stability, strength, destruction, tilt or excessive plastic deformation. Limit deformation occurring in this state is not reversed. Once the cause of structural failure that seriously.
It corresponds to the structure or components to normal use or to limit a provision on the line, including the normal appearance of deformation or vibration, deformation within the situation is still a certain elastic range. Reversible change.
