  • Table of Contents –  • List of Figures –  • List of Tables -• Body text –  • References page (APA citation format) –

STYLE  – The paper should reflect a formal, scientific tone, avoiding the unnecessary use of first-person pronouns, colloquial expressions, metaphorical phrases, and be written to an audience of your peers .

In addition to the topic-related content presented in your paper, the collaborative research paper should also use the following questions to critically analyze your chosen product, process, or technology. The questions can be answered either implicitly or explicitly as appropriate and in any order in the paper. Each question need only be addressed once in the paper by any of the authors. For example, an implicit response could be the description of a process, whereby the environmental risks, safety concerns, or overall effects on society are obvious to the reader. In cases where these concerns may not be obvious to the reader, an explicit discussion and/or explanation of the associated concerns should be included.

Historical and Current Perspectives:

  1. How and where did this technology originate ?
  2. How did this technology evolve to its current state? 3. What societal needs are met with the application of this technology (e.g., safety, convenience)?
  3. How does the use of this technology affect society (positive and/or negative consequences)? Ethical Considerations: 1. How could this technology be misused?
  4. How could the misuse of this technology affect society (e.g., safety, security, economic. etc.)? 3. How could the misuse of this technology be prevented?

 

Is ACI simplified method of analysis for continuous beams applicable to this beam? Analyze and design the beam using Robot within Rivet or program of your choice and compare the results to your hand solution.

/in /by

Accompanying figure

Design a rectangular beam continuous over three spans as shown in the accompanying figure. The live load is 2.4 kips/ft, and the superimposed dead load is 1.6 kips/ft in addition to the beam weight. Supports are 16″ wide. Assume fic = 4,000 psi, and f1= 60,000 psi.

a) Is ACI simplified method of analysis for continuous beams applicable to this beam? In any case find the critical moments per ACI Approximate method.

b) Using an analysis software, draw influence lines for moment at the center of each span and at the interior support. Employing these influence lines, determine the maximum positive and negative moments at these sections for the factored load. Draw clear diagrams of the loading for each case (i.e., load pattern). Compare these moments (elastic analysis) to those of part (a).

c) Design a rectangular section for the entire beam using the moments from part (b).

d) Draw influence lines for shear at critical sections and determine the maximum shear at each section using only full-span loading. Design the shear reinforcements using U stirrups of #3 bars if possible.

e) Analyze and design the beam using Robot within Rivet (strongly recommended) or program of your choice and compare the results to your hand solution (e.g., moment envelop from your computer model vs. moments from part (b).

  2. A computer has a 32-bit instruction word broken into fields as follows: opcode, six bits; two register file address fields, five bits each; and one immediate operand/register file address field, 16 bits.
    (a) What is the maximum number of operations that can be specified?

    (c) What is the range of unsigned immediate operands that can be provided?
    (d) What is the range of signed immediate operands that can be provided, assuming that the operands are in 2s complement representation and that bit 15 is the sign bit?
  3. A digital computer has 32-bit instructions. There are a number of different instruction formats, and the number of bits in each format used for opcodes varies depending on the bits needed for other fields. If the first bit of the opcode is 0, then there are three opcode bits. If the first bit of the opcode is 1 and the second bit of the opcode is 0, then there are six opcode bits. If the first bit of the opcode is 1 and the second bit of the opcode is 1, then there are nine opcode bits. How many distinct opcodes are available for this computer?

Civil Engineering

Develop a construction estimate based on the following Items:

  1. Tunneling
  2. A TBM costs $15,000,000 to purchase and mobilize on site
  3. Each Tunneling Contract will require its own TBM
  4. A tunneling crew costs $965.50 per hour
  5. As the result of the varying geotechnical conditions the production

rates for the TBMs for each contract will be as follows:

Contract 1a – 30 feet per 8-hour shift

Contract 1b – 12 feet per 8-hour shift

Contract 1c – 20 feet per 8-hour shift

Contract 1d – 30 feet per 8-hour shift

Tunneling will be performed on a 24-hour basis. This is the only trade that will be performed on a 24-hour basis.

  1. There is a $300 an hour shift differential for working the third shift.
  2. The operating cost of a TBM is $825 per hour
  3. The cost of soil disposal is $5.25 per cubic yard
  4. Tunnel Liner
  5. A tunnel liner costs $1,500 per linear feet.
  6. The cost of installation is included in the tunneling
  7. Tunnel Ventilation
  8. Material $515 per linear feet
  9. Labor $600 per hour
  10. Installation of Railroad Tracks

 

  1. Material $154.5 per linear feet
  2. Labor $450 per linear feet
  3. Tunnel Electrical
  4. Material $550 per linear feet
  5. Labor $710 per linear feet
  6. Station Construction
  7. Each station is 40,000 square feet
  8. Cost of construction is $472.00 per square feet

The above listed costs do not include profit and overhead which will be calculated at 15% overhead and 10% profit.

Financial Analysis

Six (6) months following the NTPDE, you are informed that a TBM that is being used on another project will become available in five (5) months including delivery and installation. This TBM is $3,500,000 less expensive than a brand-new model. However, this used TBM will generate 7-percent more spoils (excavated material that must be disposed) than the newer model. It costs $7.25 per cubic yard to dispose and transport spoils. Additionally, this machine will have a higher operating cost ($10/hr). You must develop a financial analysis to determine if utilizing this additional TBM will be cost effective from a scheduling stand point and if this savings may or not be offset by the additional costs and purchase price savings.

You should also determine what adjustment in the tasks could be made to this TBM on site and working and what Tunnel Contract it should be used on to help the schedule the most. Scheduling Issues

  1. Nine months following NTPDE, you were informed that in order to begin the construction of Tunnel Reach No. 1, new power lines will have to be installed by the local utility company. This work will take 12 months to complete by the utility company, but you cannot begin until the permits for the tunneling have been obtained. Also, the cost for this work will be $3,000,000 and has to be added to the project estimate.
  1. An environmental group files a Federal Lawsuit that will delay the permits for Station Pluto by 7-months. Also, the Owner had to spend $250,000 in legal fees and the settlement agreement for lawsuit required the owner to spend $1,000,000 in wetland mitigation. These costs have to be added to the over cost of the project.

Deliverables

  1. Develop an overall program schedule utilizing Microsoft Project or another scheduling software. The schedule should include list each task, duration, lead, and lag. You should also identify the critical path. Your schedule should take into account the scheduling issues described above.
  1. Prepare and submit a construction cost estimate based upon the information provided in this summary.
  1. Provide a written narrative discussing the project schedule which will include the overall duration, the critical path, schedule float and two specific recommendations to speed up the schedule. Your summary should be a minimum of 1,500 words (double spaced).
  1. Provide calculations to support your recommendation to purchase the used TBM. Also, provide a written recommendation summarizing your analysis and what adjustment in the schedule and associated in school need to be made to get the used machine on site and working.
  1. Submit a single document in a PDF format with a cover sheet and table ofcontents
