1. Select all the important properties of steel in its application as a structural member.

2. To weld two pieces of metal together that connect end to end, what type of weld do you utilize?

3. Which is not a method of leveling a column base plate? Select all that apply.

Solution

1.Answer.

A. Ductility of steel makes it fit to be used as a structural member. Ductile materials do not undergo abrupt/brittle failure. Ductile failure gives warning to evacuate the occupants of any structure.

E. steel when hot can be casted/moulded into desired shapes. That makes it suitable to make structural members of different shapes & sizes.

F. Steel unlike concrete is equally strong in tension and compression. That makes it ideal to be used as a structural member in situations where stress reversals can occur.

Steel has high thermal conductance, strength to weight ratio, and emissivity.

2.Butt weld is used for this purpose.

3 caulking means to seal leakage joints. This is not a method to level a column
