The tensile strength of mild steel for bolts and nuts should not be less than

For steel members not exposed to weather, the thickness of steel should not be less than

If N is the number of rivets in the joint, the strength of a riveted joint against shearing of rivets, is given by

When a large value of radius of gyration is not required

When two plates are placed end to end and are joined by two cover plates, the joint is known as

Allowable working stress corresponding to the slenderness ratio of double angles placed back to back and connected to one side of a gusset plate, is reduced to

The ratio of the span L of the filler joists to the depth d from the under side of the joist to the top of the structural concrete, should not exceed

The main advantage of a steel member, is :

Long column is one

For a cantilever beam of length L continuous at the support and unrestrained against torsion at the support and free at the end, the effective length l is equal to

The minimum width B of a solid casing for a cased beam, is equal to

For a steel member of slenderness ratiothe allowable stress iskg/cm² if it is

Pick up the correct statement from the following:

The allowable stress in axial tension is generally kept less if thickness of the member is more than

A riveted joint many experience

In case horizontal stiffeners are not used, the distance between vertical legs of flange angles at the top and bottom of a plate girder, is known as

A riveted joint may experience

The minimum pitch of rivet holes of diameter d should not be less than

For steel members exposed to weather and not accessible for repainting, the thickness of steel should not be less than

The maximum axial load which is just sufficient to keep a column in a small deflected shape, is called

Bulb angles are used in

The maximum tensile and compressive bending stress in extreme fibres of rolled I-sections and channels on the effective section, is

Rolled steel beams are :

On steel structures the dead load is the weight of

Design of a riveted joint is based on the assumption:

The permissible stress to which a structural member can be subjected to, is known as

The thickness of the web of a mild steel plate girder is less than d/If only one horizontal stiffener is used, it is placed at

The ratio of hydrostatic stress to the volumetric strain within the elastic range, is called

The effective length of a double angle strut with angles placed back to back and connected to both the sides of a gusset plate, by not less than two rivets, is

According to I.S. :-lacing bars resist transverse shear equal to
