Consider the headway data shown in the following table. Data was taken from the center lane a three-lane intersection approach for a total of ten signal cycles. For the purposes of the analysis, the data may be considered to have been collected under ideal conditions.

  1. Calculate the average headway per vehicle ID, and plot the average headways with respect to vehicle positions in the queue for the data shown below. Sketch an approximate best-fit curve through the data.
  2. Use the approximate best-fit curve constructed in Part (1), determine the saturation headway and the start-up lost time for the data.
  3. What is the saturation flow rate for this data?

A four-lane freeway (two lanes in each direction) operates at capacity during the peak hour. It has 11-ft lanes, 4-ft shoulders, and there are 3 ramps within 3 miles upstream of the segment midpoint and 4 ramps within 3 miles downstream of the segment midpoint. The freeway is on rolling terrain and has 8% heavy vehicles with a peak-hour factor of 0.85. It is know that 12% of the AADT occurs in the peak hour and that the directional factor is 0.6. What is the freeway’s AADT?

6. what is the benefit of coating steel bars with epoxy, is there any disadvantage to that?

7. why the code specify the critical section for shear in beams to be at d from the support?

8. why the code put a limit for maximum shear reinforcements in beams?

9. In beams, the concrete in tension is ignored in calculating the moment capacity, while in calculating the concrete shear capacity, the concrete in tension is included in the calculation of shear capacity, why?

10. In what mechanism the concrete shear capacity is developed?

CONCLUSION

APPENDICES

Scope:

Produce A Family Home;

Have Innovative Design;

Create A Welcoming Environment;

Have The Home Blend Into Its Surroundings;

Have Little To No Environmental Impact;

PROJECT TYPE
Home Build – Turnkey Project

Turnkey Solution To Client;

Engineering Solutions;

Engage Master Builder;

Liaise With Council Regulations;

Produce Architectural Design And Models;

Land Acquisition;

Land Development, I.E. Services To Property;

Supervision Of Construction;

Complete & Final Certification And Verification; and

Warranty Of Installed Services And Workmanship.

To test the project’s viability we have evaluated it against different factors. These factors are:

Cost, Time, Manpower and Quality.

Cost:

A project is not considered viable if its is not delivered within its budget. The cost viability of a project can change over the course of the project. However, due to the short timeframe and current trends in the market, we can assure you that project is viable from cost perspective.

Do we need to provide helicopter view of COST estimate?

Best to generate three alternatives

Top Tier: Provides all required functionality that has been requested for with top end fixtures (High-end alternatives).

Mid-Tier: Provides all required functionality that has requested, with mid-level quality fixtures:

Bottom-Tier: Provide most of the required functionality with base/entry level fixtures.

Sources of hardware;

Hardware stores: Existing agreements with hardware suppliers, and other friendly builders.

Time:

This project can be delivered on time by the requested date. A project schedule has been prepared for the project. We are confident that handover is expectedby 15-04-2019.

Project schedule provided, provides the complete timeline of the key deliverables and the final product.

To mitigate any time related issues, we have a backup team and another standby subcontractor to deliver the project on-time.

Manpower:

Manpower is important aspect in project’s viability, losing key member of a staff member can cause a project to lose its viability. In addition to our permanent staff, we have various agreements with other friendly firms, contractors, sub-contractors, and recruitment agencies.

Quality of the build is checked and tested at various stages of the projects. At the main milestones as shown on the schedule our quality assurance team shall inspect and works.

Our company is ISO certified and shall confirm with ISO 15928 standards for; Houses – Description of performance—part 5 Operating energy.

To keep the quality of the build (Whichever tier is chosen) shall be maintained by regular quality inspections.

Inspections shall be done to check the procured items, check against the specification, industry standards and regulations, it shall also whether it meets your chosen requirements (Chosen tier option).

Certificates are to be provided by the Electrician, plumbers, cablers (Data and Telephony) along with 10 years warranty and

  1. Consider a pair of 3/8 in welds that are each 10 in long. Determine the strength if these two welds if:
    1. They are loaded parallel to their length
    2. They are loaded perpendicular to their length

Do not consider simplifying assumptions

  1. Consider an L5x3x1/2 supporting 45 kip dead load and 30 kip live load. It is being welded to an ASTM A36 PL5/8x8. Design and proportion the weld to make this a simple welded connection. The leg of the weld should be the average of the minimum and maximum size.  the 5 in leg of the angle is connected to the plate.

Flexural strength design check of sections of a typical internal portal frame:

The load cases which you are expected to analyse for portal frame in this exercise, and from which the design bending moments and the coincident axial forces required for this section should be derived, are discussed in the ‘Supplementary Notes’. The moment capacities Msx and Mbx and the axial capacities Ns, Ncx and Ncy may be determined using the tables in the AISC ‘Design Capacity Tables for Structural Steel’ publication.

Rafters:
Check the flexural strength of the rafters in a typical internal portal frame, in the general vicinity of the ridge. Again, check for the two cases of maximum sagging B.M. at or near the ridge and maximum hogging B.M. at or near the ridge, and allow for the coincident axial force. Again, note that:
 The purlins in the roof are at 1250mm centres, generally.
 Assume there is fly bracing at the ridge and then at 4 spaces from the ridge (obtain value depending on frame geometry).
For the rafters assume Grade 300 steel.
