  Guangzhou steel construction terminology
1 strength: the ability of components, sections, materials, or connections to resist damage. Strength calculation is the calculation to prevent structural members or connections from failure due to the strength of the material being exceeded.
2, capacity: the maximum internal force of structure or component will not be stable or strength, fatigue and other factors can withstand the damage; or plastic analysis of failure mechanism of the formation of maximum internal force; force or reach to continue when the bearing deformation.
3, brittle fracture: generally refers to the steel structure in tension stress state, there is no warning plastic deformation and sudden brittle fracture.
4. Strength standard value: the steel yield point (yield strength) or tensile strength stipulated by the national standard.
5, strength design value: steel or connection strength standard value divided by the corresponding resistance coefficient after the numerical value.
6 、 first order elastic analysis: without considering the influence of structural two order deformation on internal force, the equilibrium condition is established according to the undeformed structure, and the internal force and displacement of structure are analyzed according to the elastic stage.
7 and two order elastic analysis: considering the influence of the two order deformation of structure on the internal force, the equilibrium condition is established according to the structure after displacement, and the internal force and displacement of structure are analyzed according to the elastic stage.
In addition to these technical terms, the Guangzhou steel structure has the following specialized terms.
8, buckling: rod or plate in the axial pressure, bending moment, shear force alone or under the joint action, suddenly occur and the original state of force does not match the larger deformation and lose stability.
9. Post buckling strength of Web: the capacity of the web to continue bearing load after buckling.
10 general high aspect ratio: parameter whose value is equal to the square root of the bending, shear or compressive yield strength of the steel, divided by the corresponding web bending, shear or local pressure elastic buckling stress.
11. Overall stability: the evaluation of buckling or buckling of the whole structure or component under external loads.
12. Effective width: width when calculating sectional strength and stability. Suppose the plate is valid
13, the effective width coefficient: the effective width of the plate and the actual width of the plate ratio.
14. Calculate the length: the geometric length of the component at its effective constraint point is multiplied by the equivalent length of the coefficient considering the deformation of the end of the rod and the load condition to calculate the slenderness ratio of the member. The length of welds to be used to calculate the strength of weld joints.
15 slenderness ratio: the ratio of length of member to gyration radius of component section.
16, slenderness ratio calculation in the overall stability of axial compression members, according to the principle of equal critical force, the corresponding lattice construction component conversion to the solid component when calculating the slenderness ratio or torsional flexural and torsional instability by bending conversion for the instability of slenderness ratio.
Guangzhou steel structure is a set of marketing, design, research and development, manufacturing, construction as one, professional construction of steel structure development enterprises. And through the international ISO9001:2008 quality management system certification and SGS factory system certification. The rapid development in recent years, has cultivated a large number of high-quality technical personnel and marketing, on-site construction team, katsukuni to customer demand, to provide effective solutions for the rational and scientific, for customers with innovative, pragmatic and enterprising spirit of solidarity to provide a full range of customer service.
