Week 5 Challenge

1)

AIM:

To check the adequacy of plate girder so that it can carry a factored shear force of 1000 KN

PROCEDURE:

RESULT:

Since, the web shear force carrying capacity corresponding to web buckling is less than maximum factored shear force , hence the given plate girder is not safe to carry a load of 1000 KN

2)

AIM:

To check whether intermediate stiffener is required or not to carry a factored load of 2000 KN

PROCEDURE:

RESULT:

Since the plate girder is not adequate to carry a load of 2000 KN, a intermediate stiffener is needed with center to center spacing of 2000 mm

3)

AIM:

To determine the web thickness required to avoid the stiffeners for carrying a factored shear force of 2000 KN

PROCEDURE:

RESULT:

Intermediate stiffeners can be avoided by increasing the web thickness of the plate girder from 12 mm to 16 mm'

4)

AIM:

To design the plate girder, determine the dimension of web and flanges without using any stiffeners and check whether the plate girder is safe to carry the maximum moment developed

PROCEDURE:

RESULT:

Web size of 1500 x 16 mm flange of 500 x 30 mm should be used to built up plate girder to carry the load of 100 kN/m and the beam is safe to resist the maximum moment developed.
