Tekla Interview Questions-TEST PAPER-1

 1. Write Types of Anchor Rod’s and its material Grade with sketches.

A. Types of anchor rod:-

1.Threaded anchor rod.

2. Hooked anchor rod.

3. Metal sleeve anchor rod.

4. Bolted anchor rod.

Material specification for anchor rods is ASTM1554 which is available in grades 36,55

and 105

2.Caliculate Minimum embedded Length for ¾ dia anchor Rod as per AISC?

A. Embedded Length for anchor Rod

=12 x diameter of anchor rod

Minimum embedded Length for ¾ dia anchor Rod

= 12 x ¾

= 9”

3. Explain ‘k’ Value.

A. k= vertical distance from outer face of flange to web toe of fillet

4. Explain about Joist.

A. joist is a structural load carrying member with an open web system which supports floor

and roof utilizing hot-rolled (or) cold-formed steel and is designed as a simple span

member.

Ex:-

16K5

where

16-nominal joist depth at mid span.

k- series or type of joist.

5- chord size of the joist.

5. Write Abbreviations for below mentioned.

a. ASCE- AMERICAN SOCIETY OF CIVIL ENGINEERS.

b. ASTM-AMERICAN SOCIETY FOR TESTING AND MATERIALS.

c. AESS -ARCHITECTURALLY EXPOSED STRUCTURAL STEEL.

d. MBMA -METAL BULIDING MANFACTURE ASSOCATIE.

e. RCSC -RESEARCH COUNCIL FOR STRUCTURAL CONNECTIONS.

f. LRFD-LOAD AND RESISTANCE FACTOR DESIGN.

g. SSPC -STRUCTURAL STEEL PAINTING COUNSIL.

h. AWS -AMERICAN WELDING SOCIETY.

i. PJP -PART JOINT PENETRATION.

j. CJP -COMPLETE JOINT PENETRATION.

6. Draw Field Weld Symbol.

7. Explain about Mill Tolerence.

A. “Mill tolerances are those variations that could be present in the product as-delivered from the

rolling mill. These tolerances are given as follows:

1. For structural shapes and plates, see ASTM A6.

2. For HSS, see ASTM 500 (or other applicable ASTM specification for HSS).

3. For steel pipe, see ASTM A53.” It is very important to consider mill tolerances during

detailing and fabrication. In some cases of complicated connections it is even advisable to

check actual shapes prior to fabrication

8. Write minimum Hole to Hole Dimension.

A. Minimum hole to hole dimension is 3d.

9. Explain About Backing bar.

A. A welding aid used to prevent melting through of a joint when preforming

ex:- complete-joint penetration groove weld.

Backing bar are used in the shop if back side of the groove is not accessiable. Field weld

will usually requires a backing bar at full penetration weld as they do not always have AIR

ARC equipment, and they are also used to prevent overhead welding to make the back

weld.

10. Write Different Types of Bolt Grades.

A. Bolts Grades:-

1. High-strength, convential bolts - A325

A490.

2. High- strength, twist-off type

tension-control bolts - F1852

F2280.

3. Common bolts - A307 .

11. Explain Difference between X and N Type Bolts.

A. X-type bolts:-

Threads excluded in the shear plane.

N-type bolts:-

Threads included in the shear plane

12. Explain About DTI’s.

A. DTI means Direct tension indicator a deformation calibrated washer used for the installation

of high strength bolts.
