List which soil strength parameters are needed to conduct a drained analysid and whoch strength parameters are needed to conduct undrained analysis

Choose the largest room in your house/apartment and measure the area.  

Let's say the room is (8*4)

Steel yield stress (fy = 60000 psi)

Concrete ultimate compressive strength (f’c = 4000 psi)

Reinforced concrete density = 150 lb/ft3.

Normal weight concrete is used.

The slab is treated as a one way slab and subjected to a dead load of 120 psf (excluding the self-weight of the slab) and a live load of 220 psf.

a.The slab is supported by beams on the edges.

b.There is a column at each corner of the slab supporting the beams.

c.Each beam is sitting on a non-load-bearing wall.

Design

- The slab

- The beams

- The columns

Carry out all ACI code checks and sketch your designs.

what is castigliano's theorem to calculate the deflection &slope of the beam Or frame.

Explain why the SMART principle often applied to objectives, is important when tendering for a project that will not get additional funds once approved.

question 1

If you were to choose on emphasizing on one of the three key dimensions to a project, which one would you choose to have more of and why?

. Explain role of the following project stakeholders i) Functional managers

ii) Project sponsor

If you were evaluating a project and only quantitative data was available for your inspection, what would you want to have more information about?

QUESTION 2: SPATIAL PLANNING AND LAND USE MANAGEMENT Discuss the logic of the four types of Spatial Development Frameworks provided for in the Spatial Planning and Land Use Management Act and indicate the scale and purpose of each of these plans.

Q.3) USE ONLY GRAPHICAL METHOD: A consolidated-drained triaxial test was conducted on a normally consolidated clay with a chamber pressure, σ3 = 172 kN/m2 . The deviator stress at failure, (Δσd)f = 227 kN/m2 . Determine (12 points): a. The angle of friction, φ' b. The angle θ that the failure plane makes with the major principal plane c. The normal stress, σf', and the shear stress, τf, on the failure plane

The bottom reinforcement in a 200mm × 500mm concrete beam is found to have corroded during its service life. Scans indicate that the effective diameter of the steel has reduced from 16?? ?? to 15?? ??. Determine the % reduction in the tensile capacity of the beam. The yield strength of the steel reinforcement is 500??Pa.

Please Answer Question Above

Please kindly answer the following question. It will be really kind if you answer all the question. Thank you.

1. Explain the importance of coefficient of curvature as you determine from the particle-size distribution curve.

2. A test group G1 compacts the soil in the compaction mould in 3 layers, giving 25 blows of rammer to each layer. Another test group G2 of your laboratory session uses 5 layers, giving 25 blows of rammer to each layer. How will the compaction test parameters (maximum dry unit weight and optimum water content) of the two groups vary?

3. Classify the soil according to USCS based on the following information:

Passing 75 µm = 10% ,Passing 4.75 mm = 70%, Uniformity coefficient = 8, Coefficient of curvature = 2.8 , Plasticity index = 4

4. Is it possible to get the specific gravity value using 3 weight measurements? Justify your answer.

5. Derive the analytical expression for the specific gravity of soil based on its basic definition.

6. Explain the importance of ZAV curve, and plot it for the soil as you see in your suburb.

7. In a liquid limit test, the crank of the Casagrande liquid limit device, as you see in the video demonstration of the test available at the BB unit site, is turned at the rate of 2 r/s so that the cup is lifted and dropped until the two parts of the soil come into contact along the bottom of the groove for a distance of 10 mm. A test group G1 followed this standard practice, but another test group G2 used 1 r/s. How do the liquid limit values vary? Explain briefly.

A negative 5% grade meets a positive 3% grade at vertex elevation 146.24m directly under an overpass bridge whose underside is at elevation 152.74 and carries another road across the grades at right angles.What is the longest parabolic curve that can be used to connect the two grades and at the same time provide at least 5 meter clearance under the bridge at its center line? If the underside of the bridge is level and is 12 meter wide, Find the actual clearance at the left and right of the bridge. Draw the diagram.

You have prepared the laboratory test report for all the tests as planned for this unit, and so you have now enough experience of conducting the tests. In future, you may establish your own geotechnical consultancy company. Write the proper order of tests as you may need to prepare for the clients. Also, provide the cost of each test as you would like to charge for these tests, including GST.

Briefly explain what are the project data and basic estimating data required in order for you to come up with your cost estimate.

Evaluate the effects of placing buildings (villages) on the slope for all 3 water table conditions(a normal water table scenario, a winter water table scenario and a drained slope scenario)
