Single span is large, multi layer Steel Structure can also be adopted. Diversified shapes, beautiful and practical. Strength
The strength index of steel by elastic stress e, yielding stress y, and tensile stress u, the design of the steel yield strength as the foundation, the high yield strength can reduce the weight of structure, save steel, reduce cost. The ultimate tensile strength is the maximum stress of U steel can withstand before failure, the structure due to plastic deformation and loss of performance, but the structure and deformation of structure does not collapse, meet the requirements of earthquake resistance. The size of the sigma u/ sigma y can be considered as a parameter for the strength reserve of steel.
2, plasticity
The plasticity of steel generally refers to the fact that the stress exceeds the yield point and has a remarkable plastic deformation without breaking. The main measure of steel plastic deformation ability is elongation and contraction rate of psi.
3, cold bending property
The cold bending property of steel is to measure the resistance of steel to crack when it is bent at normal temperature and produces plastic deformation. The cold bending property of steel is tested by cold bending test to ensure the bending deformation of steel under specified bending degree.
4, impact toughness
The impact toughness of steel material are subjected to impact load, a kind of ability in the fracture process of mechanical energy absorption, is a measure of the impact resistance of steel load effects may be due to stress concentration, temperature, and mechanical properties lead to a brittle fracture. Generally, the impact toughness index of steel is obtained by impact test of standard specimen.
5. Welding performance
The weldability of steel is a welding joint with good performance under certain welding conditions. Welding performance can be divided into two types: welding performance and welding performance. Welding performance in the process of welding refers to the welding process and the welding seam near the metal does not produce thermal crack or cooling, does not produce cooling shrinkage crack sensitivity. Welding performance is good, refers to the welding process under certain conditions, weld metal and nearby parent material does not produce cracks. The welding performance on service performance refers to the impact toughness at the weld and the ductility in the heat affected zone. The mechanical properties of the steel in the weld and the heat affected zone are not less than the mechanical properties of the base metal. China adopts the welding property test method of welding process, and also adopts the welding property test method of usability and property.
6, durability
There are many factors that affect the durability of steel. First of all, the poor corrosion resistance of steel, and must take protective measures to prevent corrosion of steel corrosion. Protective measures are: to maintain regular steel paint, galvanized steel, with acid, alkali, salt and other corrosive medium conditions, with special protective measures, such as offshore platform structure using "anode protection" measures to prevent the corrosion of the jacket, the jacket is fixed on the zinc ingots, seawater electrolytes will automatically first corrosion of zinc ingots, in order to protect the function of steel jacket. Second, because of the high temperature and long-term load, the damage strength of steel is lower than the short-term strength, so the long-term strength of steel must be measured. The steel will automatically harden and become brittle over time, i.e. "aging". The impact toughness of steel under low temperature load shall be examined
