1. Strength: member section data against damage or convergence of talent. Strength calculation is to prevent structural member or adapter due to the strength of the information to be damaged beyond accounting.
2, carrying capacity: the maximum internal force structure or component is not due to the strength, stability or fatigue and other factors can withstand damage; or plastic internal forces constitute the largest analysis of damaged tissue; or not suited to achieve sustained hosted deformation of the internal forces.
3, brittle fracture: Usually refers to the steel structure is no warning of the sudden onset of plastic deformation and brittle fracture occurs under tensile stress.
4, the intensity value specification: Country specification steel yield point (yield strength) or tensile strength. 5, the intensity value planning: specification of strength steel or convergence value is divided by the corresponding Resistance Factor after.
6, a first-order elastic analysis: not thinking of second order tectonic deformation on internal force, the establishment of equilibrium conditions in accordance with the non-deformed configuration, according to the elastic analysis during the construction of internal force and displacement.
7, second order elastic analysis: Consideration of second order tectonic deformation on internal force, the establishment of equilibrium conditions according to the configuration after the displacement, according to analysis during the elastic structure internal force and displacement.
8, reluctantly: rod or plate under axial pressure, bending moment, shear effect, alone or together with a sudden onset of stress state does not match the original large deformation and loss of stability.
9, after the web perverting strength: after barely been able to continue to maintain the web in order to carry the load.
10, GM thickness ratio: parameter whose value is equal to steel in bending, shear or compressive yield strength divided by the corresponding web flexural, shear stress or local bearing elastic perverting the square root of the quotient.
11, all the stable: under the effect of external loads on the entire structure or member or assess whether the attack perverting instability.
12 useful width: carrying out a cross-sectional strength and stability calculation width.
13 useful width factor: board member with a useful width ratio of the actual width of the plate.
14, accounting length: among its members a useful restraint points multiplied by the length of the dash Thinking equivalent length deformation and load factor suffered rod end situation obtained for slenderness ratio calculation member. When the length of the weld seam accounting convergence intensity employed.
15, slenderness ratio: the ratio of the length of the member and member accounts sectional radius of gyration.
16, conversion slenderness ratio: stable in all accounting axial compressive member, according to the principle of balanced critical force, the lattice member in terms of real time accounting web member corresponding slenderness ratio or the bend and twist torsional buckling slenderness ratio in terms of instability when winding used.
17, supportive: To reduce the lateral support of the compression member (or compression flange member) of the free length of the set, the supported member (or members compression flange) of perverting the direction of the desired applied to the member (or members subjected Ji edge) lateral force-sectional cut of the heart.
18, no support pure structure: nodes and relies on member bending to convergence, constructed to resist lateral loads.
19, strong support structure: the support structure, the support structure (support truss, shear walls, elevator shafts, etc.) greater lateral stiffness, the structure can be considered as non-sway configuration.
20, weak support structure: the support structure, the support structure lateral stiffness is weak, the structure can not be considered as non-sway configuration.
21, shaking Column: inner ends of the hinge structure can not resist lateral loads column.
22, column web node domain: RIGID node, column web area construction beams in the beam height range.
23, steel ball bearings: making structure at the supports can be rotated in the direction of the ball faces as arbitrary power transmission hinged or movable seat support.
24, rubber bearings: meet rubber and steel sheet bearing displacement and other requirements as the delivery of finished composite materials bearing reaction force support.
25, in charge of: steel construction elements, the tube member through a series of nodes, such as truss chords
26, branch pipe: steel construction, disconnected and connected at a node in charge of pipe fittings, such as truss with the competent connected webs.
27, the gap nodes: two toe tube a certain distance away from the managed node.
28 lap node: a node in the steel, two tubes of overlapping nodes.
29, the plane managed node: branch supervisor in the same plane and interrelated nodes.
30, the space managed node: branch with the competent contact in different planes constituted managed nodes.
31. The composition member: the one or more steel (or steel) consisting of interrelated components, such as I-shaped cross section or a combination of box-section beam or column.
32, steel and concrete composite beam: made of concrete and steel beams wing combination of energy all through the shear force of the beam convergence member.
