. A simply supported reinforced concrete beam needs to be designed with the following details: Size of Beam: 350 mm x 450 mm. Effective length of Beam: 8 m. Dead Load excluding self-weight of Beam: 30.5 kN/m Reinforcement: 25 mm bars and 8 mm stirrups Effective cover to compression reinforcement: 30 mm

i. Design the beam and find out the number of bars required.

ii. Design the beam for shear.

iii. Draw the detailing of beam.

Live load = 3KN/m square.
The missing values should be assume.
Extracts of BS8110

* Assume any data if missing.
* Consider fcu=40 N/mm2
, fy = fyv = 460 N/mm2
, moderate exposure condition and 1.5 hours of fire
resistance for all the questions.
* Use B.S 8110 for all your calculations and references.
* Draw the structural detailing after designing each member for all the questions.
*Unit weight of concrete as 25 kN/m3

A tangent section of highway has a -1.0% grade and ends at station 0+145 and
elevation 26 m. It must be connected to another section of highway that has a -1.0% grade and that
begins at station 1 + 350 and elevation 40 m. The connecting alignment should consist of a sag
curve, constant grade section, and crest curve, and be designed for a speed of 80 km/h. What is the
lowest grade possible for the constant grade section that will complete the alignment?

Task (1)

You work as a material engineer at an aircraft development, manufacturing and maintenance company in the MENA region. Recently, the manufactured airplanes have been experiencing crashes after a couple of years in service. You have been assigned as a member in the investigation team to identify the main cause of the crashes.

                           

  1. The shape of the designed windows of the manufactured planes is square. The investigation team suggested that this design might be the main cause of the crashes. You must provide a possible explanation of the investigation conclusion from an engineering point of view.

  1. Write the properties that should be considered when designing and manufacturing the coroners of the windows from an engineering point of view.
  1. You have been given a sample of a malfunctioned airplane wing, which is made of aluminium. The company offered you an access to a tensile testing equipment and magnetic particles inspection equipment to investigate the malfunctioning behaviour. The results of your experiment were as follows:

Table 1: Tensile Testing Results (Load Extension)

  1. Given that the length of the sample is 90 mm and the diameter of it is 7 mm.
    1. Draw the stress stain diagram.
    2. Find the yield stress (in KN/mm2).
    3. Find the ultimate tensile stress (in KN/mm2).
    4. At a point on the proportional section, calculate the modulus of Elasticity (Young’s modulus).

Hint: when calculating the Elasticity, use the stress strain numbers, not the force numbers
