A simply supported reinforced concrete beam of span 6 m is supporting a concrete slab of thickness 125 mm. Assume the overall depth of the beam, h=650 mm and Width of the beam, b=300 mm
Details of the slab supported by the beam:
Slab thickness=200 mm
Finishes=Y.X kPa
Imposed load= (X.Y) kPa
Width of slab supported by the beam=3000 mm
A) Calculate the design forces using method of sections and graphical method (method of relationships between load, shear and bending) (Design load, Design shear, Design moment) at Ultimate Limit State.
B) Calculate the maximum deflection of the beam at Serviceability Limit State. Assume E = 30 Gpa.
C) The above beam is located inside a building, closed from the external environment.
Fire resistance is 1.0 hr is required by the client.
Assume that nominal maximum aggregate size is 20mm, main bar diameter is 20 mm, shear link diameter is 10 mm, and concrete grade is Gr 30.
Find the nominal cover and minimum dimensions of the beam.
Are the dimensions assumed during the task 1 sufficient?
Assuming the following material strengths, calculate the area of reinforcement required for bending resistance at ULS.
fcu = 30 MPa, fy = 500 MPa
Calculate the area of the shear reinforcement required for the beam using high yield steel fy = 500 N/mm2 at ULS
D) What are the alternative materials that you could use for the above case? Discuss the challenges and benefits.
E) Assess the most effective support method for a given scenario, in terms of ease and speed of construction, economics, safety and environmental factors
