In the design of a multiple bay mill-type industrial building with a separate metal processing and finishing shops, what is the buildability criteria which you will use to base the structural lay-out and design of the building? Explain in details.

A rectangular concrete beam of width b= 600 mm, is limited by architectural considerations to a maximum total depth h= 400 mm. It = 542 kN.m. Design the umust carry a total factored load moment Mflexural reinforcement for this member, using compression steel if necessary. Allow 75 mm to the center of the bars from the compression or tension face of the beam. Material strengths are ??′=27.6 ??? ??? ??=413 ?? ?.
Select reinforcement to provide the needed areas, and show a sketch of your final design, including provision for No. 13 stirrups.

Sketch and explain the two components of primary and secondary moments. Explain how we use design and the material properties of rebar and concrete to counter the two moment types.

Capital Investments:

1.) Before you make a decision to acquire a large piece of equipment what tools would you use to determine if this investment is really worth the cost and how would you finance this large investment? (Please give a one paragraph brief detailed example.)

Budgets:

2.) Discuss the importance of budgeting. Then give an example of how you would control your budget as a construction manager. (Please give a one paragraph brief detailed example.)

You are conducting a geotechnical analysis on a 3-layer soil system. Layer 1 is a 5-ft sand with dry unit weight of 100 pcf. Layer 2 is a 6-ft silty sand with a saturated unit weight of 115 pcf. Layer 3 is a 15-ft low plasticity clay with a saturated unit weight of 117 pcf. There is an unknown granular soil below the clay layer. The ground water table is at a depth of 5 ft. A structural footing with dimension 5ft x 5ft is placed on top of the top sand layer. The footing must carry a load of 50,000 lbs. i. Draw a schematic diagram of the layered soil system. Show all details (6) ii. Draw the distribution of effective stresses in the soil (15) iii. Determine the effective stress in the middle of the clay layer (5) iv. At time T ≈0 (i.e. immediately after the structural load is applied), what would be the changes in total stress, pore water pressure and effective stress in the middle of the clay? Assume entire stress due to the footing is transmitted to the clay. (12) v. At time T ≈α, (i.e. long time after construction), what would be the changes in total stress, pore water pressure and effective stress in the middle of the clay? (12) vi. Laboratory consolidation test on the clay soil produced the following graph for the soil. Calculate the consolidation settlement of the clay layer when a foundation is placed on top of layer 1. Make any other necessary assumption. (50) 0.1 1 10 100
