Write to defend the view that it is engineering advisable or not to use different detailing of reinforcement for rehabilitated structures

A major road with a design speed of 90km/h intersects a minor road whose design speed is 50km/h. If the right of way of the main road is 20m while that of the minor road is 10m and that the two roads are perpendicular to each other, calculate the size of the sight triangle.

NOTE: The right of way is measured from the centre of the road. (According to TRH170

Undisturbed soil sample was collected from the field in steel Shelby tubes for
laboratory evaluation. The tube sample has a diameter of 71 mm, length of
558 mm, and a moist weight of 42.5 103 kN. If the oven-dried weight was
37.85 103 kN, and Gs 2.69, calculate the following:
a. Moist unit weight
b. Field moisture content
c. Dry unit weight
d. Void ratio
e. Degree of saturation

Classify the types of porosity that occur in ingots and cast parts and list the important factors that determine their occurrence. List the practical steps which must be taken if porosity is to be kept to a minimum in aluminium alloy with a wide freezing range cast in a sand mould.

Derive the elastic lateral torsional buckling formula of a cantilever I-beam subject to a concentrated load at the end. The load is applied at the top of the flange.

For each of the following civil engineering systems, identify one or more of the following: physical component, abstract component, rules or procedures for operation, the environment, goals or objectives, and measure of condition or performance:

a. a rail transit system

b. a hydroelectric power generation system

c. your university’s sport stadium

d. a pedestrian timber bridge spanning a large creek

Part A – Organizational Management (Functional, Project, Matrix Organizations)
A company is undertaking several complex large-scale high-technology design-build projects, requiring many high skilled engineers (structural, electrical, mechanical, piping, other). Most of the engineers are in such high-demand that they are working on more than one project concurrently.
As the project manager in charge of one such project, which form of organization (of the 3 discussed in “Organization Structures for PM”) do you recommend implementing?
Explain why the 2 other forms would be inefficient or ineffective.
Which organization structure (Project, Functional and Matrix) is most representative of the “CM at Risk” project delivery system described in the recent course materials on Contracts and Project Delivery Systems?

A coal-fired power plant proposes to burn 3% sulfur coal with a heating value of 11,000 Btu/lb. If the plant is to meet the standard of performance given by EPA New Source Performance Standards (NSPS), what percent cleanup is required for SO₂? What percent sulfur could the coal contain if the standards are to be met with no clean-up devices?

f) Discuss the following design criteria “the member must be designed adequately and safely to sustain the load i.e. ᵠR≥ᵞQ”

g) What are the difference between design and analysis of the rc section?

h) Explain the behavior of rc beam (load-deflection or Moment-curvature) under the flexural loading highlighting different stages of loading till failure; i.e. un-cracked section, cracked section, service condition, yielding and ultimate loading condition.

From load analysis, the following are the factored design forces result: Mu = 440 KN-m, Vu = 280 KN. The beam has a width of 400 mm and a total depth of 500 mm. Use f’c = 20.7 MPa, fy for shear reinforcement is 275 MPa, fy for main bars is 415 MPa, concrete cover to the centroid of the bars both in tension and compression is 65 mm, steel ratio at balanced condition is 0.02, lateral ties are 12 mm diameter. Normal weight concrete. Determine the required spacing of transverse reinforcement due to the factored shear in mm. Express your answer in two decimal places.

Calculate the required area of tension reinforcement in mm² due to the factored moment, Mu. Express your answer in two decimal places.

A Power-shift crawler tractor is excavating tough clay and pushing it a distance of 21 m. The rated blade capacity is 7.0 LCM. Maximum reverse speeds are as follows: first range, 4.8 Km/h; second range, 9.0 Km/h, third range, 12.2 Km/h. Estimate the dozer production if management conditions and job conditions are excellent and good respectively.
