A rectangular beam has a width of 300 mm and an effective depth of 510 mm. It carries Vu = 200 KN and Mu = 55 KN-m and is reinforced with 2650 mm². Use f’c = 21 MPa and fy = 345 MPa. Normal concrete. Express your answer in two decimal places.

a. Compute the shear strength in KN provided by concrete using the less conservative formula as shown. Express your answer in two decimal places.

b. Calculate the required area of compression reinforcement in mm² due to the factored moment, Mu.

c. Compute the shear force in KN to be carried by the transverse reinforcements.

d. What is the e spacing of stirrups in mm?

The concept of slab panels are designed as in a single unit, however each consisting of one or more slab items (slab panels). When it comes to design you then need to conceptualize the slab as a series of design panels. Each design panel will have its own results. Different reinforcement can be selected in different panels. More often than not, pattern loading (some panels loaded and others not). In reference to the afore mentioned; produce and explain five types panel used for slab construction. Annotated sketches can be made to support the answers.

1. A contractor is planning to use a crawler tractor with power shift transmission to push 1,500 LCY. The tractor must haul the loose material up a 12% slope where it will be stockpiled for later removal. The contractor has measured the tractor blade load measurement: the pile length 12.6 ft, the pile width 8.1 ft, and the pile height 4 ft. The tractor weighs 44,400 pounds, and the coefficient of traction is estimated to be 0.7. The average haul distance is estimated to be 300 ft. The job efficiency is 50 minutes per hour. Performance characteristics of the tractor are shown in the lecture slides. (Note: 1 mi/hr = 88 ft/min).

1) What is the estimated productivity of the tractor? (First gear for dozing; Third gear for return.)

2) Estimate the total hours to complete the work.

3) Determine if the tractor can perform the work in the given condition above.

A contractor must choose between buying or renting a crane for the duration of a 5 year construction project. The contractor uses an MARR of 8%. At the end of the project, the crane can be sold for 26% of its initial cost. The cost to operate and maintain the crane is $210,000 per year. Renting the crane costs $330,000 per year including all operating and maintenance costs. Determine the maximum amount the contractor should pay to purchase the crane (i.e. the breakeven initial cost of the crane). Express your answer in $ to the nearest $1,000
