Please select the reinforcement spacing for the entire span of a simply supported beam on a 22 ft span. Use the detailed method to calculate Vc. Do not use a shear envelope diagram use the regular shear force diagram. Use b = 16 in., d = 27 in., the main bending reinforcement consists of 4 #9 bars. The unfactored dead and live loads are 2.6 Kip/ft and 2.5 kip/ft, respectively, f’c = 4500 psi, and fy = 60,000 psi. Use #3 U stirrups. Also, locate in your beam the point beyond which no stirrups are required and find the distance from that point to the supports and to midspan. Use any allowable shear force reduction permitted by the ACI code. Provide a sketch of your final design.

Complete the bending design of a simply supported reinforced concrete beam with the following parameters: Service loads are W_D = 2.5 Kip/ft and W_L = 1.5 Kip/ft, Span = 16 ft, f'c = 6,000 psi, fy = 40,000 psi, b = 12 in., cover to the center of the steel = 3 in. Assume phi = 0.9, but make sure that phi is actually 0.9 at the end. Find h by doubling the recommended minimum height for this beam and provide it in whole inches rounded up to the nearest inch.

Design a rectangular footing for an 18-in square interior column with a dead load of 210 k and a live load of 180 k. Make the length of the long side equal to twice the width of the short side, fy = 60,000 psi, fc' = 4000 psi, normal weight, and qallowable= 3650 psf. Assume the base of the footing is 5 ft 0 in below-grade , γ concrete = 150 pcf and γ soil = 100 pcf. Also, assume h=24 in and cover = 4.5 in .

Answer the following questions :

a- Find the required area then the dimensions of the footing .

b- Check one way shear.

c- Check the punching shear.

d- Design the reinforcement in both directions .

For an edge flat panel, given that Vu=160 k , slab thickness = 10 in, d = 9 in, fc'= 3000 psi , fy = 60000 psi, column dimensions 24 x 24 in . Answer the following questions : a- Is shear reinforcement required ? (show your calculations) b- Will shear reinforcement solve the problem ? (show your calculations) c- Determine the parameter required to resist the given ultimate shear load then find a . d- Determine the stirrups spacing S . e- Determine the number of stirrups .

Explain how concrete cubes are manufactured on site under the following titles; sampling,

compaction, curing and traceability

The Mass Moment of Inertia of a body is a property that measures the resistance of the body to angular acceleration

The Parallel-Axis Theorem is I = I_G + md²

The resultant (summation) moment about the mass center due to all the external forces is equal to the moment of inertia about center of mass times the angular velocity of the body.

Mathematically, three equations with four unknowns cannot be solved.

The kinetic energy of a rigid body can be expressed as the sum of its translational and rotational kinetic energies.

To find the kinetic energy of a rigid body with Pure Translation, the rotational kinetic energy is not zero.

Reactions at fixed supports do no work because the displacement at their point of application is zero.

Why should project manager even if only involved in the financial aspects of a project be aware of codes, standards, acts regulations and building legislation

Design a constructed wetland that can effectively treat a domestic wastewater containing high content of BOD and ammonia N.

After drilling generally casing is done. Assume in one well the casing failure has taken place due which the operator has faced a problem in the well. Based on understanding how the selection of different types of casing is done (4marks). Support your answer with a neat diagram (1mark).

Suggest possible ways to significantly reduce the size of a common secondary sewage treatment plant (e.g. Shatin Sewage Treatment Plant) without lowering the treatment performance.

You are overseeing the plans for construction of a new highway. Someone proposes using cheaper,
substandard materials to control/treat water flowing off the construction site. The water on the
construction site contains measureable concentrations of sediments, oils from vehicles, heavy metals, and
components of asphalt. A recreational lake is nearby and downgradient from the construction site. This is
a substantial slope (10% grade) across the site.

pillar.
b) (5 points) Assuming you are a licensed engineer, what is your ethical obligation to the public
AND other licensed engineers working on this job? [Your response should cover ethical
obligations to both parties.]
c) (5 points) LIST and DESCRIBE at least two ways to control fluvial (water) erosion on this site.
