Week 4 Challenge

Solution.1)

Aim: To classify the given sections as Plastic, Compact, Semi- Compact or Slender.

Procedure:

Result: Hence, the Setions are classified as Plastic, Compact, Semi-Compact or Slender as per IS 800:2007.

Solution.2)

Aim: To find the effective length of the Rafter madeup of Built-up I section.

                                   

Procedure:

Result: Effective length of the rafter is determined and equal to 977.5 mm.

Solution.3)

Aim: To determine the deflection in the beam for the given conditions and find the flexure stiffness for the given value of deflection.

  

Procedure:

                          1.           

                        2.                

Result: Deflection and the flexure stifness for the given beam andloading conditions have been obtained as :

i) Deflection = 0.0639 mm

ii) Deflection = 0.6368 mm

iii) Flexural Stiffness = 26 x `10^7 Nm^2`

Solution.4)

Aim: To design a beam for given loading condition and determine its moment carrying capacity. 

Procedure:

Result: Hence, a ISWB 600 @ 133.7 kg/m can be choosen as it is safe in Shear, Moment, Deflection, Buckling and Bearing.

Solution.5)

Aim: To design channel purlin for the given conditions.

Procedure:

Result: Hence, we will use ISMC 200 as it is safe in shear, moment and deflection.
