all quantities or liquidation of inventory) nswer the following questions: A. For A36 and A992, list major advantages and disadvantages of these materials with regards to design, availability, constructability. Which of the grades of steel results had the lowest average price per pound? If cost of a member is generally directly proportional to section properties, cross- sectional area and moment of inertia, comment on the implications of steel grade on the total cost of a project. (Hint: Resistance Load-Cross Section x Yield Strength) B. C. (Please cnecn uuuu policy on the new grade and its availability.)

Solution

For A36,

Advantages and disadvantages -

For A992, Advantages and disadvantages –

b) A36 steel has the lowest average price per pound, because in the market the cost of A36 is 350-400 USD/Ton whereas the market cost of A992 steel ranges from 450-550USD/Ton.

c) Implications of steel grade on the total cost of a project

We know that, Resistance load = Cross section*yield strength

The yield strength of A36 is 36ksi and of A992 is 50ksi.

Therefore the use of A992 steel over the A32 steel in the project increases the total cost of the project.
