Buckling Load

The load at which a member or a structure as a whole collapses in service or buckles in a load test.

Dead Loads

The self weights of all permanent constructions and installations including the self weights of all walls, partitions, floors, and roofs.

Effective Lateral Restraint

The restraint which reduces sufficient resistance in a plane perpendicular to the plane of bending to restrain the compression flange of a loaded strut, beam or girder from buckling to either side at the point of application of the restraint.

Elastic Critical Moment

The elastic moment which will initiate yielding or cause buckling.

Factor of Safety

The factor by which the yield stress of the material of a member is divided to arrive at the permissible stress in the material.

Gauge

The transverse spacing between parallel adjacent lines of fasteners.

Imposed (Live) Load

The load assumed to be produced by the intended use of occupancy including distributed, concentrated, impact and vibration and snow loads but excluding, wind and earthquake loads.

Load Factor

The numerical factor by which the working load is to be multiplied to obtain an appropriate design ultimate load.

Main Member

A structural member which is primarily responsible for carrying and distributing the applied load.

Pitch

The center to center distance- between individual fasteners in a line of the fastener.

Secondary Member

Secondary members is that which is provided for stability and or restraining the main members from buckling or similar modes of failure.

Welding Terms

Unless otherwise defined in this standard the welding terms used shall have the meaning given in IS: 8121957.

Yield Stress

The minimum yield stress of the material in tension.
