1 Glossary

1 strength

The capacity of resisting failure in member cross-section material or connection. Strength checking aims at preventing failure of structural members or connections from exceeding the material strength.

2 load-carrying capacity

The largest internal force that a structure or member can bear without failure from strength, stability or fatigue, etc., or the largest internal force at the onset of failure mechanism in plastically analyzed structures; or the internal force generating a deformation that hinders further loading.

3 brittle fracture

In general, the suddenly occurred brittle fracture of a steel structure subject to tensile stress without warning by plastic deformation.

4 characteristic value of strength

5 design value of strength

The value obtained from division of the characteristic value of strength of steel or connection by corresponding partial factor of resistance.

6 first order elastic analysis

The elastic analysis of structure internal forces and deformation, based on the equilibrium condition of undeformed structure, taking no account of the effect of the second order deformation on infernal forces.

7 second order elastic analysis

The elastic analysis of structure internal forces and deformation, based on the equilibrium condition of deformed structure, taking account of the effect of the second order deformation on internal forces.

8 buckling

An abrupt large deformation, not conforming to the original configuration of members or plates subject to axial force, bending moment or shear force, and thereby causing loss of stability.

9 post-buckling strength of web plate

The capacity of web plates to bear further loading after buckling.

10 normalized web slenderness

Parameter, equal to the square root of the quotient of steel yield strength in flexion, shear or compression by corresponding elastic buckling stress of web plates in flexion, shear or local compression.

11 overall stability

Assessment of the possibility of buckling or loss of stability of structures or structural numbers as a whole under the action of external loading.

12 effective width

That part of plate width assumed effective in checking the section strength and the stability.

13 effective width factor

Ratio of the effective width to the actual width of a plate element.

14 effective length

The equivalent length of a member obtained by multiplying its geometrical length within adjacent effective restraining points by a coefficient taking account of end deformation condition and loading condition. The length of welds assumed in calculation of the strength of welded connections.

15 slenderness ratio

The ratio of member effective length to the radius of gyration of its cross-section.

6 equivalent slenderness ratio
