Question

Design of Flexural Members:

Here you have learnt how to design simple steel beams of rolled steel sections subjected to transverse loading.

You have also known how to take care of elastic instability of flanges and web, so since they might not fail due to buckling under compressive stresses.

You have also learnt how to check for stresses within beams subjected to biaxial bending.

The last bending stress acting at any point within a section subjected to biaxial bending is given by

f =(M_v/I_uu )v+(M_v/I_vv)u

The inclination of α of the neutral axis along with the principal axis OU is given by

tan α =- I_uu/I_vv tan θ

where,            tan θ = M _v/M_u .
