TEKLA INTERVIEW questions test paper-2

 1.What is the difference between steel bar and steel plate

The difference between plate and bar is based upon size and production procedure. Flat stock has

historically been classified as a bar if it is less than or equal to 8 in. wide, and as a plate if it is

greater than 8 in. wide. See the AISC LRFD Manual of Steel Construction, third ed., page 1-9 for

discussion

3.Explain About DTI Washer?

DTI means “direct tension indicator,”a deformation-calibrated washer used for the installation

of high-strength bolts.

4.Explain About Beveled Washer & It’s condition ?

Beveled washers are used to compensate for a lack of parallelism between the outer faces of a

bolted joint as is found in such cases as a joint involving the flange of an American standard beam

(S-shape). To do so, the beveled washer must be properly oriented in the assembled joint. The

square or rectangular shape simplifies proper orientation during installation.

5.Name three methods for setting a column base to proper elevation

The use of a leveling plate, leveling nuts, and shim stacks are three alternatives. These and other

methods are discussed in greater detail in the AISC LRFD Manual of Steel Construction, beginning

on page 11-54

6.What is the definition of “backgouging”?

According to AWS D1.1.-2000, backgouging is “the removal of weld metal and base metal from

the weld root side of a welded joint to facilitate complete fusion and complete joint penetration

upon subsequent welding from that side

7.What is a “batten plate”?

A batten plate is a plate element used to rigidly join two parallel components of a built-up

the roof..

9.Explain about girt?

A horizontal member in the side or end of a building used to support side covering.

10.Explain about sweep & Camber with sketches?

Camber: A comparatively flat vertical curve placed in a truss,beam or girder to counter act a part

of deflection.

Sweep: A comparatively flat vertical curve placed in a truss,beam or girder induced through

cold bending or by the application of heat.

11.Explain about E-Plans?

A drawing consisting of line diagrams representing framing in plan,elevation,section etc to

which are added principal dimensions,erection marks,notes and, when required,enlarged details,thus

providing the erector with sufficient information to place the members in the structure.These

drawings donot normally show the erection scheme,schedule,rigging devices,temporary

supports,safety devices etc.

length of anchor rod = embed+projection

= (12d)+(Gt+BPt+2d+1/2)

= 12(3/4) + 2 + 1 ¾ + 2(3/4) + ½

= 4'-2"3/4.

14. What diameter hole is currently recommended in a base plate for a 1” diameter anchor

rod?

or the full effort of an ironworker using an ordinary spud wrench to bring the plies

into firm contact.
