Week 5 Challenge

ANSWER NO 1

AIM:

Design of Plate Girder

1. Shear resistance of web problem

Determine PG Web thickness for given load without stiffener

For a PG of size 1200 x 300 x 25x 10, Check if the web is adequate to carry a factored shear force of 1000 kN. Yield strength of plate fy is 250 Mpa.

PG size 1200x300x25x10
Factored shear force = 1000 KN
fy= 250 N/mm2

ANSWER NO 2

AIM:

2. Check whether intermediate stiffener required for given load

For a PG of size 1500 x 500 x 30 x 12,check if the intermediate web stiffener is required to carry a factored shear force of 2000 kN, if required, find the spacing of stiffener. Yield strength of plate fy is 250 Mpa.

ANSWER NO 3

AIM:

3. Check whether intermediate stiffener required for given load

For the above problem, determine the web thickness required to avoid the stiffeners.

ANSWER NO 4

AIM:

4. Proportioning problem

Calculate the minimum depth & web thickness requirement of a beam of span 15 m to carry a UDL of 100 kN/m. Also calculate the flange depth & thickness considering section to be plastic and check if the assumed size is adequate to carry the moment.
